The present invention relates to detecting a user's obstructed view, and more specifically, to an object obstructed from the user's view due to the user's hand.
A computer system implemented method for assistance viewing an object includes receiving, by a computer system, first data from a first sensor sensing an object when a user's view of at least a portion of the object is obstructed by a hand of the user. The first sensor is fixed to a first wearable device. The computer system generates an image of the obstructed portion of the object in response to the first data. An image of the obstructed portion of the object is projected onto a surface within a view of the user.
In other embodiments of the invention, other forms are provided, including a system and a computer program product.
Features and advantages of the present invention will be more readily understood with reference to the attached figures and following description, wherein:
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.

A second device 130 is worn by a user, such as on a wrist band 134 of user's hand 112. One or more of the added software modules may be configured to communicate information from device 120 to device 130 identifying the obstructed part 126 of display content 124. In response, a projector 132 of device 130 projects an image 116 of the obstructed part 126 of display content 124, such as onto the back of hand 112, as shown.

In one way for obtaining and projecting image 216, visual spectrum camera 236 is included in smart watch 230 fixed in a position that is proximate to object 220, such as on a part of wrist band 234 facing object 220, as shown. Camera 236 captures a first image 201 showing at least the obstructed portion 226 of object 220. Another image 202 corresponding to the user's eye view 214 is captured from further away and shows an unobstructed part 228 of object 220 but not obstructed part 226. (For example, image 202 may be obtained from a camera 242 of smart glasses 240 worn by the user who is wearing smart watch 230 on the user's hand 212.) Then, a part of image 201 that corresponds to the obstructed part 226 of object 220 is determined and provided as another image 216 by comparing images 201 and 202. The comparing indicates what is shown in image 201 but not shown in image 202, which is the obstructed part 226 of object 220.
To perform the comparing, etc., images 201 and 202 may be sent by their respective devices 230 and 240 to remote computer system 250 configured to perform the identification of what is shown in image 201 but not image 202 to responsively generate image 216 and send it to smart watch 230 for projecting. Alternatively, smart watch 230 may be configured to perform the image comparing, identifying and generating, in which case image 202 may be sent by smart glasses 240 to smart watch 230, which generates image 216 and projects it. In yet another alternative, smart glasses 240 may be configured to perform the image comparing, identifying and generating, in which case image 201 may be sent by smart watch 230 to smart glasses 240, and then smart glasses 240 may send generated image 216 to smart watch 230 to project image 216.

The analysis determines whether part 226 obstructed from user's view 214 poses a hazard, i.e., whether part 226 could potentially cause injury to the user. For example, part 226 may pose a hazard because it includes a bare conductor as shown in portion 327, whereas the rest of the conductors nearby are insulated. Likewise, part 226 may pose a hazard if includes one or more portions 327 that are sharp, extremely hot or cold, energized at a high voltage, or moving (e.g., rotating or vibrating at high frequency), for example. Accordingly, device 230 may include sensors known in the art to remotely detect shape, temperature, voltage level and movement, including vibration and rotation. (The term “sensor” herein may include a device, such as a camera, that not only senses, but also processes sensor data, such as to enhance or normalize what is sensed, and provides processed sensor data.)
More specifically, one or more of images 201, 202 and 216 may be analyzed by a computer program executing in one or more of device 230, device 240 and remote computer system 250, wherein the program is configured to detect any hazard in obstructed part 226 such as described herein above. Also, or alternatively, data from sensors of one or more of device 230 and device 240 may be analyzed by a computer program executing in one or more of device 230, device 240 and remote computer system 250, wherein the program is configured to detect, via the sensor data, any hazard in obstructed part 226 such as described herein above.
In one aspect, the user is warned if the analysis detects a hazard, which may be by any one or more warning actions performed by device 230, device 240 or both, including, for example, generating a vibration, an audible sound, and projecting something different on the back of hand 212, which may be any one or more of a warning icon on image 216 (
Device 230 may be in the form of a ring, a bracelet, a smartwatch, or other computer device suitable for wearing near the user's hand that has hardware and program modules configured to perform functions described or illustrated herein. In at least one embodiment, device 230 has program modules, hardware and program modules associated with the hardware, including image projector(s) 232 (e.g., micro projector(s) or pico projector(s)), sensors 831, obstruction detection module 832, perspective determination module 834, hazard determination module 836 and communication module 838 configured for communicating over network 850. Device 230 also includes a control interface that has a microphone, a speaker, a vibrator and a computer program module for generating hazard warning vibration and sounds and for detecting and responding to voice commands from the user, including requests to project image 216. (It should be understood that device 230 may include additional elements, fewer elements, different elements or differently arranged elements.)
Device 240 may be in the form of a head mounted device, such as a device affixed to a headband on the user's forehead or a device affixed to or built into glasses worn over the user's eyes, for example, and that has hardware and program modules configured to perform functions described or illustrated herein. It should be appreciated that in addition to the functions of device 240 explicitly described herein, such as herein above in connection with
Remote computer system 250 may be implemented by a computer system such as illustrated in
Sensors and sources 831 and 841 include ultrasound source(s) and sensor(s), proximity sensor(s) and camera(s), which provide data received by obstruction detection module(s) 832, 842 and/or 852 for identifying an obstructed portion 226 of an object 220 (
Sensors and sources 831 and 841 described above may also provide data to hazard determination module 836, 846 and/or 856 for the module(s) determining whether a hazard exists in the obstructed part 226 of object 220 such as by image analysis to determine whether the obstructed part 226 includes anything sharp, anything above or below a predetermined temperature threshold, exposed wire, bare wire in contrast to insulated portions of wire and vibration or rotation. Sensors and sources 831 and 841 may also include electromagnetic field sensor(s) that provide data to hazard determination module 836, 846 and/or 856 for the module(s) determining whether part 226 includes anything above or below a predetermined voltage threshold and laser source(s) and sensor(s) provide data to hazard determination module 836, 846 and/or 856 for the module(s) determining whether part 226 includes anything vibrating or rotating above a certain predetermined frequency.

If the object is closer than the predetermined distance, this may also be used to indicate that part of the object is presumed to be obstructed by the user's hand from the user's view. Alternatively, an image of the object may be generated as described below to determine whether part of the object is obstructed by the user's hand from the user's view.
For generating 930 the image of the obstructed portion of the object, the computer system may be configured to use merely the ranging data, provided that its nature is suited for producing the image, e.g., provided that the sensor that produces the ranging data is lidar or ultrasonic, for example. (The system may possibly be configured to determine proximity even from optical sensor data, in which case optical ranging data may be suited for producing the image.) Alternatively, the computer system may be configured to generate the image of the obstructed portion of the object from the ranging data together with additional sensor data. In yet another alternative, the computer system may be configured to generate the image from data received from one or more other sensors instead of the ranging data from ranging sensor(s).
In at least one embodiment of the present invention, the computer system generates 930 an image of the obstructed portion of the object merely from first data generated by at least one ultrasonic source and sensor fixed to the first wearable device, where the first wearable device is adapted to be worn on a hand of the user with the at least one source and sensor fixed on a side of the hand opposite the user's head. (Herein, “on the hand” includes on the user's wrist.) In at least one such embodiment, the at least one source and sensor of the hand wearable device may be lidar based. In at least one such embodiment, the computer system generates the image that is limited to the obstructed portion of the object merely from first data generated by at least one optical sensor fixed to the hand wearable device.
In at least one embodiment of the present invention, the computer system generates 930 an image that is limited to the obstructed portion of the object both in response to the above described first data and from second data generated by at least one second sensor fixed to a second wearable device, such as a device adapted to be worn on the user's head, e.g., eyeglasses, goggles or a device fixed to a forehead strap. In such an embodiment, the first and second sensors may include respective first and second optical cameras (i.e., optical light sensing cameras), for example, where the first data includes first image data for a first image of the object from the first camera and the second data includes second image data for a second image of the object from the second camera. (The first and second sensors for generating 930 the image that is limited to the obstructed portion of the object may alternatively include respective first and second ultrasonic or lidar sensors fixed to the first and second devices respectively.)
In this alternative, that generates 930 an image that is limited to the obstructed portion of the object, the first image is captured from the object side of the user's hand, which is the opposite side from the user's face. Consequently, the first image includes the portion of the object obstructed by the hand of the user. The second image is captured from the same side of the user's hand as the user's face, so that the user's hand obstructs the user's view of the object and, correspondingly, the view of the sensor(s) of the head wearable, second wearable device. Consequently, the second image does not include the portion of the object obstructed by the hand of the user, and the portion of the first image not included in the second image shows the obstructed portion of the object. The computer system compares the first and second image data and generates, as the image limited to the obstructed portion of the object, the portion of the first image not included in the second image.
Once the computer system has generated the image of the obstructed portion of the object, the image is projected 940 onto a surface viewable by the user, such as by a projector of the first device configured to project the image onto the back of the user's hand. Since the object is closer than the predetermined distance from the user's hand and, therefore, reachable by the hand, the system is configured to also detect 950 whether the obstructed part of the object presents a hazard to the user's hand, as has been described herein. Responsive to detecting 950 that there is such a hazard, the system is configured to provide a warning action for the user, as has been described herein, which may include a hazard warning to the user via the projected image of the obstructed portion as has been described, which may include presenting a magnified part of the projected image of the obstructed portion, wherein the magnified part shows a hazardous part of the obstructed portion of the object, as shown in
The following provides a detailed description of aspects concerning a cloud computing embodiment of the present invention. It is to be understood that although this disclosure includes this detailed description regarding cloud computing, implementation of the teachings recited throughout this application are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portility (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. Reference herein to a “procedure” is not necessarily intended to indicate implementation of invention embodiments in a procedural language.
The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be accomplished as one step, executed concurrently, substantially concurrently, in a partially or wholly temporally overlapping manner, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
One or more databases may be included in a host for storing and providing access to data for the various implementations. One skilled in the art will also appreciate that, for security reasons, any databases, systems, or components of the present invention may include any combination of databases or components at a single location or at multiple locations, wherein each database or system includes any of various suitable security features, such as firewalls, access codes, encryption, de-encryption and the like.
The database may be any type of database, such as relational, hierarchical, object-oriented, and/or the like. A database product that may be used to implement the databases is IBM® DB2®, or other available database products. (IBM and DB2 are trademarks of International Business Machines Corporation, registered in many jurisdictions worldwide.) The database may be organized in any suitable manner, including as data tables or lookup tables.
Association of certain data may be accomplished through any data association technique known and practiced in the art. For example, the association may be accomplished either manually or automatically. Automatic association techniques may include, for example, a database search, a database merge, GREP, AGREP, SQL, and/or the like. The association step may be accomplished by a database merge function, for example, using a key field in each of the manufacturer and retailer data tables. A key field partitions the database according to the high-level class of objects defined by the key field. For example, a certain class may be designated as a key field in both the first data table and the second data table, and the two data tables may then be merged on the basis of the class data in the key field. In this embodiment, the data corresponding to the key field in each of the merged data tables is preferably the same. However, data tables having similar, though not identical, data in the key fields may also be merged by using AGREP, for example.

Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable sub combination. Also, although features can be described above as acting in certain combinations and even initially claimed as such, features from a claimed combination can in some cases be excised from the combination, and the claimed combination directed to a subcombination or variation of a subcombination.
