System for vision impaired users to execute electronic transactions

A method of enabling an electronic payment for a visually impaired user may be disclosed. The visually impaired user may proceed to use the payment device and enter the braille code which may be communicated to an authority using a first channel to begin a transaction. The system may communicate a verification code to the portable computing device using a second communication channel. The user may enter the verification code which may be communicated to an authority via the first communication channel.

Calibration of haptic device using sensor harness

A haptic calibration device comprises a signal generator configured to receive the subjective force value and the force location from a subjective magnitude input device. The signal generator also receives from at least one of a plurality of haptic sensors a sensor voltage value, with the at least one of the plurality of haptic sensors corresponding to the force location. The signal generator stores the subjective force value and the corresponding sensor voltage value in a data store. The signal generator generates a calibration curve indicating a correspondence between subjective force values and sensor voltage values for the location where the subjective force was experienced using the data from the data store, wherein the calibration curve is used to calibrate a haptic feedback device.

Envelope encoding of speech signals for transmission to cutaneous actuators

A haptic communication device includes a speech signal generator configured to receive speech sounds or a textual message and generate speech signals corresponding to the speech sounds or the textual message. An envelope encoder is operably coupled to the speech signal generator to extract a temporal envelope from the speech signals. The temporal envelope represents changes in amplitude of the speech signals. Carrier signals having a periodic waveform are generated. Actuator signals are generated by encoding the changes in the amplitude of the speech signals from the temporal envelope into the carrier signals. One or more cutaneous actuators are operably coupled to the envelope encoder to generate haptic vibrations representing the speech sounds or the textual message using the actuator signals.

Speech translation and recognition for the deaf

An application on a mobile phone or tablet computer or eyeglasses listens to the speech of a profoundly deaf person and interprets it in real time. It can then repeat it in a normal voice. The voice recognition is trained to the voice of the profoundly deaf person.

Assistive device for the visually-impaired

Devices, systems, and methods for providing auditory sensory substitution using an assistive device are disclosed. Objects in the real-world are observed by a depth camera and classified. The classification is used to identify a sound corresponding to the object. In some cases, the position of the object can also be used to identify the sound. The device is configured to permit vision-impaired players to participate in athletic events.

Testing computer program accessibility for users with disabilities, such as for use with mobile phones

Disclosed here is a system to enable interaction between a user with a disability and a computer program. The system can obtain a representation of a user interface to present to a user. The system can determine an element associated with the user interface, where the element is configured to provide information to the user, however, the user interface presentation of the element at least partially fails to provide the information to the user. Based on the element, the system can determine an appropriate test to perform. The appropriate test indicates at least two of: a test to perform with a keyboard, a gesture test to perform with a mobile screen reader, and an audio test to perform with a screen reader. The system can generate an indication of the appropriate test. The system can provide the indication of the appropriate test prior to releasing the user interface to the user.
