A method for navigational assistance for the visually impaired can include determining that an image captured by an imaging device contains an unknown object and determining that the unknown object is not resolvable within a threshold period of time. The method can further include performing an operation to reallocate computing resources between memory devices couplable to the imagining device in response to determining that the unknown object is not resolvable within the threshold period of time. Data corresponding to the unknown object can be written to the reallocated computing resources and an operation involving the data corresponding to the unknown object can be performed to resolve the unknown object using the reallocated computing resources.

The ultrasonic sound guide system presents the audio broadcasting system based on the inaudible ultrasonic sound to assist the indoor and outdoor navigation of the visually impaired. The transmitters are placed at the point of interest to propagate the frequency modulated voice signal in ultrasonic sound range. The receiver device is carried by the visually impaired in wearable device form to receive the ultrasonic sound for the voice signal via demodulation. Since the ultrasonic sound demonstrates the acoustic properties, the directivity, attenuation, and superposition of ultrasonic sound provide the acoustic clue to the receiver device user for localizing the transmitter positions. The visually impaired hear the designated voice signal and follow the signal strength to arrive at the specific location. The ultrasonic sound guide system is useful device to localize the place in near field without touching the braille. The receiver device can be any independent form such as eyeglasses, neckband, walking cane attachment device, hand-held device, etc. those are not blocking the ear canal. Also, the receiver device can be realized by smartphone application software using the hardware and sensors in the smartphone.

A voting apparatus for receiving a ballot paper comprises a voting aid for overlying the ballot paper, the voting aid comprising a respective ballot marking aid for each voting option of the ballot paper. The apparatus includes an audio system and an activation button for voting option. The audio system audibly renders the relevant ballot information in response to operation of any one of the buttons.

A password input method is disclosed. The password input method is conducted by a microprocessor of a touch sensitive password input device, wherein the touch sensitive password input device is integrated in an electronic device, such as point-of-sale payment terminal, smartphone, tablet computer, all-in-one computer, door station, and keyless electronic door lock. In case of the password input method according to the present invention being conducted, the touch sensitive password input device is controlled to guide a visually impaired person to successfully complete a password input operation with high security.

Some implementations include methods for communicating features of images to visually impaired users. An image to be displayed on a touch sensitive screen of a computing device may include one or more objects. Each of the one or more objects may be associated with a bounding box. A contact with the image may be detected via the touch sensitive screen. The contact may be determined to be within a bounding box associated with a first object of the one or more objects. Responsive to detecting the contact to be within the bounding box associated with the first object, a caption of the first object may be caused to become audible and the touch sensitive screen may be caused to vibrate based on a vibration pattern unique to the first object.

A device and a method storing accommodation measure evaluation data that associates an accommodation measure for a person in a minority group with evaluation of the accommodation measure are provided. When the accommodation measure to be provided for the person in the minority group is input, an evaluation of the accommodation measure to be provided is acquired based on the input accommodation measure and the accommodation measure evaluation data, and the evaluation is displayed on a display monitor or the like. Furthermore, a higher evaluation is given to a specific accommodation measure (first accommodation measure) than another accommodation measure (second accommodation measure), which enables the more detailed evaluation to be performed.

Implementations described herein relate to methods, systems, and computer-readable media for accessible computer-user interactions. For example, a method can include displaying a graphical user interface on a display screen. The graphical user interface includes a virtual assessment, the virtual assessment is representative of an assessment examination, and the graphical user interface further comprises a graphical element that represents a portion of a logical problem of the assessment examination. The method can also include receiving a signal indicative of placement of a physical object onto the display screen above the graphical element, repositioning the graphical element responsive to physical movement of the physical object on the display screen, and generating a portion of an assessment score based at least in part on one or more of: physical movement of the physical object on the display screen, the signal, or the repositioning of the graphical element.

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.

Electrostatic friction textures on a touchscreen panel are used to create the sensation of block icons in a contextual menu adapted to an automotive environment. In particular, a center stack touchscreen friction display in a passenger vehicle provides one set of touch controls and HMI data to the driver while simultaneously providing either the same control options and HMI or a completely different set of information and menu structure to the passenger in invisible texture form. The invisible texture is in the form of block icons, and coincidence between a finger of a passenger and a block icon results in an audio announcement of the block icon to guide a visually impaired passenger through the contextual menu.

A method for aligning an input interface (240) of a touchscreen (230) with an overlay (210) for the touchscreen (230) is provided. The method comprises receiving a touch input on the touchscreen (230), wherein the touch input identifies a first position on the touchscreen (230) corresponding to an alignment mark (220) of the overlay; determining, based on the received touch input, a region of the touchscreen (230) in which to render the input interface (240); and rendering the input interface (240) in the determined region of the touchscreen (230).
