The present disclosure relates generally to the field of electronic device testing systems and more specifically to the field of electronic device testing equipment for testing smart phones and tablets.
Automated System Level Testing (ASLT) can be used to execute automated tests that quickly perform measurements and generate test results that can then be analyzed. An ASLT assembly may be anything from a computer system coupled to a meter, to a complicated automated test assembly that may include a custom, dedicated computer control system and many different test instruments that are capable of automatically testing electronics parts or testing devices such as smart phones. ASLT systems both reduce the amount of time spent on testing devices to ensure that the device functions as designed and serve as a diagnostic tool to determine the presence of faulty components within a given device before it reaches the consumer.
ASLT systems to test smart phones, for example, are required at both the point of sale and at the production facilities. Currently, if a user experiences a problem with their phone and brings it into a retail facility, there are no systems in place to exhaustively test the hardware and software on the phone to determine the source of the problem with a high degree of accuracy. Some retail facilities have the capability of performing some basic software testing of the phone, however, no retail facility has the ability to perform a complete hardware and software test on the phone and to test all the functions on the phone automatically. Accordingly, the phone either needs to be returned and replaced, which over time can result in substantial costs to the manufacturer. Alternatively, if the phone cannot be returned or replaced for any reason, the customer ends up dissatisfied if the problems with the phone are not easily diagnosed and fixed.
In some cases, the problem with the phone cannot be diagnosed at the retail facility. This is referred to as a No Trouble Found (NTF) or No Fault Found (NFF) condition. In such cases, the phone is sent to a repair center where a battery of tests are performed to determine if there is any issue. Currently, even the repair centers do not have a satisfactory solution to automatically test all the hardware and software functions on a smart phone.
While some software testing methodologies are in place, typically, a human has to manually test many of the device's hardware and software functions to ensure that the device is working adequately. Further, even if the device is repaired, there is no traceability for the repair work performed or any fully automated method for verifying that the repair work was performed satisfactorily. A person has to manually test the device to ensure that the device is working properly. Accordingly, the repair and test methodologies currently in place are subjective and not foolproof. Any errors in the repair or verification process will cost the manufacturers more money and result in customer dissatisfaction. Further, sending the phone to a repair center will almost always leave a customer dissatisfied as most customers cannot afford to be without their smart device for an extended period of time.
Additionally, the production facilities at which the phones are manufactured also do not currently have any mechanisms in place for complete hardware and software automated testing of the phone devices. Most of the functional testing that takes place before the phones are packaged is manual and, accordingly, it is error-prone and expensive. Further, the cost and susceptibility to error of the manual test processes currently in place is increasing as the feature-set on the devices increases.
Accordingly, a need exists for an automated tester system that can address the problem of testing phones, e.g., smart phones at retail facilities, repair centers, and production facilities. What is needed is an automated tester system that can automatically perform a wide range of hardware and software functional tests on a smart phone.
Embodiments of the present invention provide a tester system (hereinafter referred to as the “Smart Box”) that allows a user to perform a series of hardware and software tests in a closed and controlled environment, thus eliminating subjectivity of manual testing. Embodiments of the present invention are also optimized for speed and configured to test the major features of the phone in a short duration of time. Further, embodiments of the present invention transmit all test data to a centralized server enabling mobile operators to track feature issues, model issues, geographic and/or store issues. Accordingly, embodiments of the present invention are enabled for global analytics.
In one embodiment, the Smart Box is a box-shaped apparatus comprising robotics that allows the smart device to be moved in the x, y and z directions.

In one embodiment, a user can place the smart device inside the Smart Box and use a computer connected to the Smart Box to select one or more tests to be applied to the device. The test software on the computer interacts with Smart Box to engage the smart device under test and the robotics of the Smart Box to exercise the various functions of the smart device. Each test is performed and compared against pass/fail criteria. A pass/fail determination is made and the following test is performed. In one embodiment, reports are automatically generated reporting the results of the various tests and sent to the cloud server.

Smart Box for Automatic Feature Testing of Smart Phones and Other Devices
Embodiments of the present invention provide a tester system (hereinafter referred to as the “Smart Box”) that allows a user to perform a series of hardware and software tests in a closed and controlled environment, thus eliminating subjectivity of human testing. Embodiments of the present invention can be optimized for speed configured to test the major features of the phone (or tablet) in a short duration of time. Further, embodiments of the present invention transmit all test data to a centralized server enabling mobile operators to track feature issues, model issues, geographic and/or store issues. Accordingly, embodiments of the present invention are enabled for global analytics.
In one embodiment, the Smart Box is a box-shaped apparatus comprising a robotic arm that allows the smart device to be moved in the x, y and z directions. Further, the apparatus comprises a stylus attached to the robotic arm that can also move in the x, y and z directions and be used to actuate buttons on the smart device. In one embodiment of the present invention the smart device moves in the x and y direction while the stylus moves in the z direction. Accordingly, embodiments of the present invention are configured to allow the stylus and mobile device the mobility so that the stylus can make contact with the device at any location on the device.
In one embodiment, a user can place the smart device inside the Smart Box and use a computer connected to the Smart Box to select one or more tests to be applied to the device. The test software on the computer interacts with Smart Box to engage the smart device under test and the robotics of the Smart Box to exercise the various functions of the smart device. Each test is performed and compared against pass/fail criteria. A pass/fail determination is made and the subsequent test is performed. In one embodiment, reports are automatically generated reporting the results of the various tests and sent to the cloud server.
Embodiments of the present invention are advantageous because they help reduce No Trouble Found (NTF)/No Fault Found (NFF) occurrences at both point of sale, repair center and production facilities by executing simple automated functional and specification tests on devices. Embodiments of the present invention leverage digital and physical robotics automation to test for problem scenarios in a controlled environment. Further, embodiments of the present invention implement test automation platforms to orchestrate problem scenarios, thereby leveraging the Smart Box's robotic test enclosure combined with robust test emulators. The Smart Box platform further targets a low-cost scalable profile with a simple and easy to use experience targeted at point of sale and repair center end users.
Embodiments of the present invention also help to isolate quality issues and classify true failures. By automating the testing process, human subjectivity is eliminated, thereby, standardizing the test process. Further, embodiments of the present invention provide a mechanism to verify and validate repairs, thereby, ensuring consistency and accuracy. Accordingly, the cost to manufacturers is decreased, device returns are decreased and customer satisfaction is increased. Further, embodiments of the present invention capture end-user experience metrics allowing performance to be tracked over time.
Devices that have no detectable faults can readily be determined using the Smart Box technology thereby avoiding costly repair/diagnostic outsourcing. Also, if a device is faulty, the fault or defect can efficiently and automatically be determined using the Smart Box technology versus time consuming and error prone manual testing techniques. Also, intermittent faults can more accurately be detected. By removing manual testing steps, device testing can be made more efficient, more effective and more reproducible. Also, test results over many devices can more easily be compiled for archiving and analysis purposes.
The test automation software running on computer 130 can be, for example, the QUICKSTRESS testing platform for lab and live testing which, among other things, allows testers of smart devices to easily record macros and have them playback across different models and manufacturers. As will be explained below, the test automation software, e.g., QUIKSTRESS, etc. can be designed to identify and troubleshoot customer-experience issues at the point of sale, and to reduce the No Fault Found (NFF) devices at the repair centers to save costs for both OEMs and operators.
In one embodiment, when an end user connects to the Smart Box 110 using computer system 130 after placing the device to be tested in the Smart Box 110, user interface 120 will begin to guide the user through a series of options for conducting the requisite tests. In one embodiment, the various tests can be grouped into different categories, e.g., tests associated with the display, the audio, the battery, sensors, camera, and keypad, etc., as shown in user interface 120. Other exemplary categories may also test the touch screen, physical buttons, gyro and accelerometer.
The user can select either one or all of the tests to execute within a certain category. Alternatively, the user can select all the tests within all categories to execute at the same time. The test automation software running on computer 130 will determine the tests that can be executed simultaneously versus the tests that are to be executed serially. Upon user selection, the tests will then execute and provide conclusive and actionable results.
Embodiments of the present invention allow information to be communicated from the smart device and components within Smart Box 240 to system controller 230 while the smart device is being tested and for commands to flow from the system controller back to the smart device. For example, the smart device being tested may be used to take a picture of a physical reference image and the information could be communicated to system controller 230 to determine if it matches the reference image stored in memory to determine if the camera on the smart device is functioning properly. Embodiments of the present invention are, therefore, capable of manipulating the smart device both physically and through software, and are also able to collect diagnostic information in real-time using the system controller to determine if the smart device is functioning normally.
In one embodiment, the physical features/instrumentation of the Smart Box include the enclosure 315, the robotic elements, the sensors and instruments, the plate that holds the smart device DUT and the electronics to interface with and drive testing of the DUT. This case includes the robotic mechanisms for holding and automatically moving the DUT and for automatically physically interfacing with the touch screen and other physical buttons of the DUT to simulate human interaction therewith.
As will be explained in further detail below, this case includes the various Smart Box sensors that detect output from the DUT such as a camera, a microphone, a flash detector, wireless signal detectors, interfaces to read the contents of the DUT memory, and interfaces to pick up signals from the audio jack, etc. The case also includes the various instruments that can stimulate the DUT, such as a speaker, a wireless signal broadcaster, external speaker, motion devices on the plate that holds the DUT, a robotic stylus, a USB charger interconnect, a wireless charger device, etc. This case also includes the logic, that can be integrated with the Smart Box, or external thereto, for performing the actual testing and automated control of the physical elements/robotic elements/instruments of the Smart Box, e.g., using the QUIKSTRESS software.
In one embodiment, the Smart Box 300 comprises an image plate 350. The image plate comprises a physical reference image that is fixed inside of the Smart Box and can be used to test the front and rear camera functionality of the smart device. In one embodiment, the physical reference image can comprise a color chart. In one embodiment, a separate image plate can be used for each of the front and rear cameras. Reference images identical to the physical reference image 350 can be stored in an image library within the automated tester software running on terminal 130.
The smart device 355 and the Smart Box 300 can be controlled via an appropriate communication protocol (e.g., USB, Wi-Fi etc.) using the tester software running on terminal 130. The software launches and controls the camera application on smart device 355. The software also controls the smart device 355 and the robotics (e.g. stylus 385, smart plate or platform 345) to move and position the smart device 355 in an appropriate location relative to the image plate 350. The software also activates the camera on the smart device to capture an image (using either the front or the back camera or both simultaneously if the Smart Box is equipped with multiple image plates). The software can also be configured to retrieve the image from the smart device camera and compare the retrieved image with the reference image stored on terminal 130 to determine if the camera passes or fails the test. In one embodiment, the comparison threshold for determining a pass or fail is user configurable.
In one embodiment, Smart Box 300 comprises a custom phone holder 310. The custom phone holder is customizable and can be customized for all the different models of smart devices. Because each smart device has a different form factor, a customizable phone holder is required to accommodate the various form factors. In order to test a different smart device (e.g., switching from testing an iPhone to a Samsung phone), the custom phone holder 310 in Smart Box 300 would need to be swapped out. In one embodiment, the custom phone holder 310 may be affixed to the plate or platform 345 using one of several means (e.g., clamps, screws, dowels, etc.)
In a different embodiment, the smart plate 345 and custom holder 310 are designed and manufactured as a single unit with each model of smart device requiring a different plate unit. Accordingly, in one embodiment, the entire plate 345 is swapped out in order to test a different model phone. In one embodiment, the Smart Box can comprise a robotic arm that can automatically swap out a smart plate if a user sends a command from terminal 130 to test a different model phone.
In one embodiment, the plate 345 is configured to move in the x-y direction while the stylus 385 (and the robotic arm attached thereto) moves in the z direction. Also the smart plate 345 can be configured to rotate so as to alternate the phone 355 between a portrait and landscape orientation. In one embodiment, the smart plate 345 may also be configured to tilt in the theta-x and theta-y directions as well.
In one embodiment, Smart Box 300 comprises a stylus 385. The stylus 385 can be a capacitive stylus with a soft tip similar to those used by hand on touch-screen devices as an alternative to finger touch. The stylus 385 can be controlled by the robotics within Smart Box 300. For example, the stylus 385 can be attached to a robotic arm that allows movement in the z plane. As mentioned previously, the Smart Box 300 has a mechanism to allow at least three-dimensional movement of the smart device under test and sensors relative to each other. In one embodiment, the smart device is placed a stage (or smart plate 345) that can move in the X-Y dimensions while the stylus 385 and other sensors are mounted on an arm moving in the Z dimension. In a different embodiment, the robotic arm and the stylus attached thereto can move in all three x, y and z planes.
In one embodiment, Smart Box comprises an external camera 360. It should be noted that in different embodiments, the Smart Box can also comprise multiple cameras. External camera 360 can be a high resolution camera operable to take high resolution pictures of any sized smart device. The camera 360 can be mounted in a fixed position within the Smart Box and is connected to and controlled by the tester software on terminal 130. The camera 360 can be used to take pictures of the DUT display during one of the several tests using the camera, e.g., a touch-screen test implementation. Alternatively, the camera 360 can be used to take pictures of calibration-related images as part of a robotic calibration process run by the Smart Box and test automation software. In a different embodiment, the camera 360 can move in the z direction and be adjusted to accommodate different sized smart device screens.
In one embodiment, the Smart Box 300 comprises two audio capture devices 380 and 395, an external microphone 330, an audio dampening module 340, and an external speaker 390 that are used to test the various audio features of the smart device. In different embodiments, either more or less audio capture devices or speakers may be available. The audio capture devices 380 and 395, in one embodiment, may be connected to the tester automation software through a USB or Wi-Fi connection (or any other appropriate protocol). The audio capture devices may be able to both source and capture high quality stereo audio. Sourcing can be done through a 3.5 mm stereo output, while capture is done through a 3.5 mm stereo input or ¼″ microphone input for instance. The audio capture devices can be used, for example, to test the speaker phone capability on the smart device and to test the sound quality through the microphone jack on the smart device.
In one embodiment, the speaker 390 and microphone 330 connect to the audio capture devices and are positioned in a relatively close position to the speakers and microphones on the smart device. The speakers and microphone are used to test the receiver and headset/microphone jack on the smart device respectively. In one embodiment, the Smart Box also comprises a 3.5 mm audio signal splitter to split the headphone and microphone inputs. The splitter splits a 4-connector plug that is plugged into the jack on the smart device into a 3-connector jack for stereo device output and a 2-connector jack for mono device input.
In one embodiment, the automation test software integrates mobile voice quality testing modules. For example, the test software can integrate POLQA, a software library includes perceptual measurement software that calculates audio quality by comparing a degraded file to a reference file. POLQA is standardized by the International Telecommunication Union (ITU-T) and using the POLQA library allows the test automation software to determine the quality of the audio files received from the smart device in accordance with an industry standard.
In one embodiment, the Smart Box can also include an audio dampening module 340 to mitigate any noise issues and provide audio insulation for the Smart Box enclosure 315. In most embodiments, the enclosure encloses the Smart Box on all sides in order to minimize noise. The front door, however, can be removable as shown in
In one embodiment, the Smart Box 300 also comprises an external accelerometer 320. The accelerometer can be mounted on the smart plate 345 and connected to the system controller (e.g., automation software running on terminal 130) to be used for monitoring vibrations.
In one embodiment, the Smart Box comprises an external programmable light source (not shown in
In one embodiment, the Smart Box can also comprise an external light sensor or meter (not shown in
In one embodiment, the Smart Box may include a capacitive object (not shown in
In one embodiment, the Smart Box may also include a fingerprint device (not shown in
In one embodiment, Smart Box 300 can also comprise a powered USB hub 370. The USB hub 370 can provide power to the various components of the Smart Box, e.g., microphone, audio capture devices, etc. However, the present invention is not limited to simply USB powered devices but also encompasses other methods of providing power and communicating with the various components of the Smart Box.
The Smart Box 420 comprises integrated robotics for x and y direction movements of the smart plate 345. It also includes integrated stylus finger 385 that can move in the z direction. The Smart Box may also comprise fixed reference images, e.g., images on image plate 350.
The Smart Box can also comprise a powered USB that is used to power an external camera, external audio capture and generator devices (e.g., speakers and microphones), external light sensor, external light source, external proximity device, and an external finger print device.
As also shown in
The USB hub 541 is used to supply power to the various external components within the Smart Box and the smart devices 510A-510C. For example, the USB hub powers the lights 551, the dual audio capture and generator devices 552 and 555, the accelerometer 554, the microphone 553, the Bluetooth dongle 520, and the speaker 556 can all be powered using the USB hub 541. Further, the USB hub 541 is also operable to communicate information between the various components and the test automation software on system controller 540. This configuration is advantageous because it allows embodiments of the present invention to stress the phone physically while being in communication with the automation software on system controller 540 at the same time. For example, the stylus and the smart device 510A may be interacting physically at the same time as an application package is being downloaded to smart device 510A from the test software to stress the memory or CPU.
In one embodiment, each custom phone holder 765 will have its own device code and this information will be communicated to the system controller in order to determine what type of device 770 is placed into the custom phone holder. For example, the custom phone holder can be equipped with a QR code, which is communicated to the system controller.
As mentioned previously, in one embodiment, the smart plate 715 and the custom holder 765 constitute a single unit having a unique QR code. This QR code can be communicated to the system controller via USB or Wi-Fi. In another embodiment, the smart plate (or base plate) 715 can comprise dowels for affixing the custom holder 765 onto the smart plate.
The system controller can use the QR code to determine device specifications, e.g., thickness of device, diagonal length of screen, etc. and to calibrate the phone. For example, the robotics may be used to touch a single point on the screen using the stylus and use the information from the contact to determine where the smart device is positioned relative to the stylus and other components. In other words, the QR code and robotics in combination with the system controller can be used to perform an x-y calibration on the phone to determine its precise location. Once the x-y calibration is performed and the corners of the device are located, the system controller can determine where the various physical and soft buttons, e.g., Home button are on the device. Once a device is calibrated, its information can be saved in a calibration file on system controller and retrieved the next time the same device is tested.
In one embodiment, the calibration information can be communicated to other components within the Smart Box that interface with the smart device. For example, once the diagonal length of the screen is determined through the calibration process, the stylus can be programmed by the system controller to adjust to the screen size of the smart device.
The calibration information and device specifications can then be used by the robotics within the Smart Box to actuate either on or off-screen buttons on the smart device. For example, when the device specifics are known, the stylus can be programmed to actuate the Home button on the smart device.
Accordingly, embodiments of the present invention can drive the smart device from the system controller through the USB or Wi-Fi connection. In one embodiment, the system controller draws information from the smart device, e.g., metadata regarding information being displayed on the smart device screen. Subsequently, using the calibration information, the metadata, and device specifications, the system controller can determine the location for active regions on the touch screen panel, soft buttons and physical buttons on the smart device screen. This information can be translated to an X-Y coordinate or location for the robotics to interact physically with the smart device.
In one embodiment, the Smart Box can comprise actuators 780 (also controlled by the system controller) or servos used to activate buttons on the smart device. For example, actuators can be used to activate the volume buttons, ring silent switch, and/or the wake/sleep button. The actuators can either be moulded into the smart plate itself or they can be outside the plate and configurable. In one embodiment, the stylus 385 itself can also be programmed by the system controller to activate the buttons.
In one embodiment, actuators or servos may be used to insert the power cable into the phone. Accordingly, the custom phone holder should be able to hold the device physically secure so that the power cable into the smart device. The actuators may either be built into the custom phone holder itself or be external. Similarly, with the audio connections, e.g., headphones, microphone, etc., actuators may be built into the phone holder in order to plug in the various connections.
In one embodiment, in order to reduce human intervention and further automate the testing process, the Smart Box 300 can be equipped with a robotic arm that places the smart device into the custom phone holder.
In one embodiment, the smart plate underneath the custom holder can rotate in order to switch the device from portrait to landscape mode. Also, in one embodiment, the smart plate can comprise hinges that allow it to rotate around the x or y-axes in order to test the gravity sensors and gyro functionality of the smart device.
In one embodiment, the smart plate can have a temperature sensor built into it. The temperature sensor can, for example, measure the heat emanating from the device using infrared technology. Also, the smart plate can have a heating or cooling element built into it to artificially raise or lower the temperature of the smart device to determine its operating specifications.
In one embodiment, the smart plate can also have a vibration sensor built into it. The vibration sensor allows the vibrate feature of the smart device to be tested.
As explained above, embodiments of the present invention are advantageous because they allow: a) physical interaction with the phone using (e.g. using a stylus, sound, light, etc.; b) automated control of the phone using a system controller and an appropriate communication protocol (e.g., USB or WiFi); c) application packages installed in the system controller that stress the phone; and d) comprise external sensors that monitor the phone, e.g., audio, camera, accelerometer, etc. The below series of figures and flowcharts provide an illustration of the manner in which embodiments of the present invention perform the various tests on a smart device.
Testing the Smart Device Touch Screen
At step 902, a reference image is stored in the memory of system controller 820. At step 904, communication is established between the system controller 820 and the smart device 830, and also between the system controller 820 and the robotics 850 within the Smart Box. In one embodiment, this communication is performed using USB, Wi-Fi or any other suitable protocol. The communication, in one embodiment, can flow through USB hub 810.
At step 906, a sketchpad application is launched on the smart device. In other embodiments, different applications may be used for testing the touch screen.
At step 908, the robotics 850 (e.g., stylus 840, smart plate etc.) and the smart device are controlled to draw test images on the smart device touch screen.
At step 910, the sketched image is retrieved from the smart device.
Finally, at step 912, the retrieved image is compared with the reference image stored in the system controller memory to determine if the device passed or failed the test.
As mentioned above, embodiments of the present invention advantageously allow robotic components within the Smart Box to physically interact with the phone while the smart device is being manipulated through software and information is being retrieved from the smart device for analysis using a system controller.
Further, embodiments of the present invention can advantageously test the entire screen by making contact with all areas of the screen using the stylus to ensure that all the pixels on the screen are functioning properly. This eliminates human error and is more efficient that prior methods of testing screens on smart devices that required active human interaction and contact.
Also, in one embodiment, the stylus can be used to draw various shapes on the device screen to test for on-screen lineation and multi-spot touching. For example, the stylus can be used to trace a circle or draw a square and the information can be captured by the system controller to determine if the touch screen is functioning properly. The stylus can also be used to test gesture recognition functionality on the touch screen.
