Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The disclosure relates generally to methods and systems for displaying data, and, more particularly to methods and systems that can determine how to display different data according to at least one image captured by an image capture unit.

2. Description of the Related Art

Recently, electronic devices, such as smart phones, notebooks, wearable devices or other portable devices, have become more and more technically advanced and multifunctional. For example, portable devices have network connectivity capabilities. Users can use their portable devices to connect to networks at anytime and anywhere. The convenience and new functionalities advanced by modern technology have made these devices into necessities of life.

On the other hand, an AR (Augmented Reality) technology has been widely used in applications for environment navigation, commercial purposes, as well as other fields. AR is a way to observe the real environment by integrating environment entities and a VR (Virtual Reality) technology. AR technology can use an image recognition technology to detect and track physical objects within images, and use a 3D technology to combine and display physical objects with preset virtual objects via a screen.

Generally, users can obtain information, such as additional data corresponding to physical objects which is not provided in the real environment via AR technology. Currently, the information displayed in a virtual object is typically fixed. In other words, no matter how users observe the virtual object, only the information which has been preset for the virtual object can be provided to the users. Consequently, there exists an opportunity to enrich the AR experience by providing various and flexible information by virtual objects. This can greatly expand the applicability of AR technology.

DETAILED DESCRIPTION OF THE INVENTION

Systems and methods for displaying data are provided.

FIG. 1 is a schematic diagram illustrating an embodiment of a system for displaying data of the invention. The system for displaying data can be used in an electronic device, such as a computer, or a portable device, such as a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a GPS (Global Positioning System), a camera or a tablet.

The system for displaying data 100 comprises an image capture unit 110, a display unit 120, a storage unit 130, and a processing unit 140. The image capture unit 110 can perform an image capture process to obtain at least one image. The display unit 120 can display related information, such as the image captured by the image capture unit 110, interfaces, and/or data. The storage unit 130 stores the image captured by the image capture unit 110, and/or related data, such as user interfaces and data corresponding to at least one virtual object.

The system for displaying data 100 can have network connectivity capabilities by using the network connecting unit. In some embodiments, the virtual object in the storage unit 130 can be obtained from a server via a network. On the other hand, in some embodiments, the system for displaying data 100 can have AR technology, thus it can display the image captured by the image capture unit 110 and the virtual object via the display unit 120 in real-time.

FIG. 2 is a flowchart of an embodiment of a method for displaying data of the invention. The method for displaying data can be used in an electronic device, such as a computer, or a portable device, such as a mobile phone, a smart phone, a PDA, a GPS, a camera or a tablet.

In step S210, an image corresponding to at least one specific object is captured by an image capture unit of the electronic device. Then, in step S220, it is determined whether the distance between the electronic device and the specific object has changed. It is understood that, in some embodiments, another image can be later captured via the image capture unit of the electronic device. The determination of whether the distance between the electronic device and the specific object has changed is performed according to the respective size of the specific object in the two images. For example, when the size of the specific object becomes larger, it is determined that the distance between the electronic device and the specific object has changed. Specifically, it is determined that the electronic device is closer to the specific object. In some embodiments, movement information corresponding to the electronic device can be detected by a motion sensor, such as an accelerometer and/or a Gyro sensor of the electronic device. The determination of whether the distance between the electronic device and the specific object has changed is performed according to the movement information. For example, when the electronic device moves toward to the view direction, it is determined that the distance between the electronic device and the specific object has changed. Specifically, it is determined that the electronic device is closer to the specific object. In some embodiments, the electronic device has a sensing unit, such as a laser rangefinder for detecting the distance between the electronic device and the specific object. The determination of whether the distance between the electronic device and the specific object has changed is performed according to the distance between the electronic device and the specific object. It is noted that, the above methods for determining whether the distance between the electronic device and the specific object has changed are only examples of the present application, and the present invention is not limited thereto. When the distance between the electronic device and the specific object has not changed (No in step S220), the procedure remains at step S220. When the distance between the electronic device and the specific object has changed (Yes in step S220), in step S230, first data is displayed via a display unit of the electronic device. It is understood that, in some embodiments, only when the distance between the electronic device and the specific object becomes closer, step S230 is performed.

FIG. 3 is a flowchart of another embodiment of a method for displaying data of the invention. The method for displaying data can be used in an electronic device, such as a computer, or a portable device, such as a mobile phone, a smart phone, a PDA, a GPS, a camera or a tablet.

In step S310, an image corresponding to at least one specific object is captured by an image capture unit of the electronic device. Then, in step S320, the captured image is displayed via a display unit of the electronic device. In step S330, the image is analyzed with an image recognition process, and in step S340, it is determined whether the specific object in the image is a predefined object. It is understood that, in some embodiments, when the specific object comprises a specific text, a specific number, and/or a specific symbol, it is determined that the specific object is the predefined object. In some embodiments, when the specific object has a specific shape, such as a circle, triangle or rectangle, it is determined that the specific object is the predefined object. In some embodiments, the predefined object may be a business card 400 with a rectangle shape, as shown in FIG. 4. When the specific object is not the predefined object (No in step S340), the procedure goes to step S310. When the specific object is the predefined object (Yes in step S340), in step S350, second data is displayed via the display unit of the electronic device. It is understood that, in some embodiments, the second data comprises at least one virtual object. It is noted that, the virtual object can be generated using an image processing technology, and the virtual object can be displayed in the display unit. It is noted that, in some embodiments, specific data can be displayed in the virtual object. Then, in step S360, it is determined whether the distance between the electronic device and the specific object has changed. Similarly, in some embodiments, another image can be later captured via the image capture unit of the electronic device. The determination of whether the distance between the electronic device and the specific object has changed is performed according to the respective size of the specific object in the two images. In some embodiments, movement information corresponding to the electronic device can be detected by a motion sensor, such as an accelerometer and/or a Gyro sensor of the electronic device. The determination of whether the distance between the electronic device and the specific object has changed is performed according to the movement information. In some embodiments, the electronic device has a sensing unit for detecting the distance between the electronic device and the specific object. The determination of whether the distance between the electronic device and the specific object has changed is performed according to the distance between the electronic device and the specific object. It is noted that, the above methods for determining whether the distance between the electronic device and the specific object has changed are only examples of the present application, and the present invention is not limited thereto. When the distance between the electronic device and the specific object has not changed (No in step S360), the procedure remains at step S360. When the distance between the electronic device and the specific object has changed (Yes in step S360), in step S370, first data is displayed via a display unit of the electronic device. Similarly, in some embodiments, only when the distance between the electronic device and the specific object becomes closer, step S370 is performed. It is noted that, in some embodiments, the first data comprises detail contents for the specific data. In some embodiments, specific data is first displayed in the virtual object, and the specific data is replaced by the first data when the distance between the electronic device and the specific object has changed, such that the first data is displayed in the virtual object.
