In a first aspect of the invention, it is claimed a computer-implemented method for assisting the movement of a visually impaired user by means of a wearable device 1, comprising the following steps: S1—Acquiring data from the environment of the visually impaired user S2—Fusing the acquired data, creating, repeatedly updating of a Live Map S3—Determining, repeatedly updating and storing, of at least one navigation path together with associated navigation guiding instructions for the visually impaired user to navigate from the current position of the visually impaired user to a point of interest, repeatedly selecting one preferred navigation path from the at least one navigation path, and repeatedly sending to the visually impaired user the preferred navigation path, together with associated navigation guiding instructions.

A method includes displaying, on a touchscreen, a video comprising a video frame and determining, based on a saliency map of the video frame, a region of interest in the video frame. The method also includes detecting a touch on a region of the touchscreen while the video frame is displayed and generating a haptic response in response to determining that the region of the touchscreen overlaps with the region of interest.

Disclosed herein are example embodiments of systems and methods of braille transceiving. A braille input output transceiving device (BIOTD) comprises a transceiving module configured to receive braille codes, encode the braille codes into DTMF tones, and transmit the DTMF tones. The BIOTD enables transmission over various types of media, including audio DTMF tones and any networked communication device that can accept audio tones in the appropriate format.

Various embodiments of a three-dimensional (3D) tactile map system and methods of implementing the system are described. In one example, the tactile map system includes a map base having a substantially planar substrate defining an x-y plane. The map base includes a top base surface and a bottom base surface, where the top base surface includes a ground surface texture. The tactile map system also includes a 3D scaled representation of a structure attached to the top surface of the map base. The 3D scaled representation can be configured with dimensions that are in proportion to the structure and extend in a z-direction from the base. The z-direction being orthogonal to the x-y plane. The 3D scaled representation includes a plurality of identified surfaces, each of the plurality of identified surfaces having a surface type of a plurality of surface types, each surface type corresponding to a selected surface texture.

Systems, devices, and methods for software development or modification. The disclosed technology relates to transforming interactions with physical blocks by a human developer on an activity surface into computer-understandable digital information or logic for developing or modifying software (e.g., websites or mobile applications) in real-time or near real-time. The physical blocks are representative of software elements used in software development. For example, the structures, colors, shapes or hardness/softness/squeeze/bend/flex/elastic/shape-memory/rigid properties, whether symmetrical or asymmetrical, whether open-shaped or close-shaped of the physical blocks can determine which software elements are being developed and the arrangement of the blocks can be mapped to how the software elements are to be included in the software. Users located remotely from the developer can provide annotations or feedback to the software being developed in real-time.

A method, computer system, and computer program product for providing spatial weather map data to the visually impaired are provided. The embodiments may include receiving a weather map image that contains weather information and a subject of interest, wherein the subject of interest comprises a user current location, a business location, or an asset location. The embodiments may also include receiving a request from a user for current time, historical or forecast data depicted in the weather map and a request for a geo-location of the subject of interest. The embodiments may further include generating sounds corresponding with the requested weather map data, wherein the generated sounds appear to the user to originate in a particular direction and at a particular distance from the subject of interest, wherein the apparent location of the sounds correspond with a weather map feature including the location of approaching or surrounding weather.

An assistive device and method for non-visually discerning a three dimensional (3D) real-world area surrounding a user, comprises a haptic feedback interface. The assistive device receives input to select a mode in the assistive device and based on the selected mode, determines each of a plurality of objects within a first proximity range of the assistive device as a relevant object or a non-relevant object to obtain a set of relevant objects and a set of non-relevant objects. The assistive device determines a scaling factor based on the first proximity range and the selected mode, and further adjusts sizes of the set of relevant objects to map the set of relevant objects with a set of haptic elements of the haptic feedback interface. The assistive device generates touch-discernible feedback on the haptic feedback interface to enable the user to non-visually discern the 3D real-world area surrounding the user.

A haptic feedback device for providing haptic sensation includes a haptic feedback interface that includes a plurality of haptic elements. The haptic feedback device receives a plurality of videos each recording a real time or near-real time event in a three-dimensional real-world area from a different viewing angle. The haptic feedback device receives a user input that indicates a selection of an image-capture device from the plurality of image-capture devices. The haptic feedback device detects a plurality of different motion associated with a plurality of objects in an upcoming scene of a video captured by the selected image-capture device based on a look-ahead buffer of the video. A haptic feedback is determined for the upcoming scene of the video. One or more movable haptic cues are generated on the haptic feedback interface using the plurality of haptic elements in synchronization with a current scene of the video.

Various examples described herein are directed to systems, methods, and computer-readable medium for providing a tactile response. A document that includes visual data is received. Change data for the visual data that indicates changes in data values of the visual data from a previous time is received. The visual data is rendered. An indication that a section of the document is selected is received. The section includes a first visual data. A change of the first visual data is determined front the change data. A tactile response unit is controlled to provide a tactile response based on the change of the first visual data.

The embodiments of the present disclosure provide a display panel, a display device, and a method for displaying Braille information. The display panel includes a plurality of scan lines, data lines, and display circuits arranged at intersections of the plurality of scan lines and the plurality of data lines. The display circuit includes a switch configured to be turned on or off according to a scan signal from the scan line, and a dot element coupled to the switch. The dot element includes a substrate, an electrode provided on the substrate, a thermosensitive layer provided on the electrode, and a dot key arranged on the thermosensitive layer.
