The present invention relates to a smart phone case combination keyboard for the blind that includes: a cover main body having a mounting space to which a smart phone is mounted so as to expose a display unit on an upper surface, a plurality of lower key holes formed toward downward on a lower surface, and a front key hole respectively formed on a left and right of a surface toward frontward; a keyboard cover embedded in the main body, having a plurality of keys respectively protruded through the lower key holes and operated by a thumb of a hand gripping the cover main body as a first front key and a second front key are protruded through each of the front key holes; a communication module performing communication between the smart phone and the keyboard; and a controller that controls to perform pairing with the smart phone through the communication module and to transmit a key input signal of the keyboard to the smart phone through the communication by the communication module. According to the present invention, the smart phone may be stably gripped and the stable typing enable due to the keyboard arrangement on the lower surface while protecting the smart phone from external impact, and it is possible to provide the call mode along with the keyboard arrangement to enable the convenient use of the blind and improve the speed and accuracy of the typing through the use of the thumb that is not normally used for the typing, the unwanted separation may be prevented by the comfortable and stable gripping.

Techniques for providing adaptive assistive technology for assisting users with visual impairment can be used on a computing device. These techniques include displaying content to a user, capturing a series of images or video of the user using a camera, analyzing the series of images or video to determine whether the user is exhibiting behavior or characteristics indicative of visual impairment, and rendering a magnification user interface on the display configured to magnify at least a portion of the content of the display based on a determination that the user is exhibiting behavior or characteristics indicative of visual impairment. The magnification user interface may be controlled based on head and/or eye movements of the user of the computing device.

Provided is a text message playing method. When a text message is received, an incoming call interface is displayed, where the incoming call interface includes a control function region which is used for controlling whether to play the text message. A first operation instruction to the control function region is received, and the text message is played in a preset playing mode, where the first operation instruction is used for instructing to play the text message. In this way, a humanized and diversified text message playing style is gained, and user experience is improved through a simple and convenient operation. Further provided are a terminal and a computer-readable storage medium.

A display device and a haptic feedback display method of the display device are provided. The display device includes a display panel including a display region, and a touch-control sensor disposed at least in the display region and used to detect a touch-control operation. The display device also includes a control unit electrically connected to at least the display panel. The control unit is used to change an operation mode of the display device, and according to the touch-control operation detected by the touch-control sensor, to adjust a display object of the display panel. The operation mode includes at least a blind operation mode. Further, the display device includes at least one button structure disposed in the display region. In the blind operation mode, a touch surface of the display device is in a raised state at a location of a button structure of the at least one button structure.

There is provided a signal control device including a signal output unit that outputs a signal for a vibratory device, and a signal control unit that controls the signal. Between a case where a change from a reference level to a first level is exerted on the signal and a case where a change from the first level to the reference level is exerted on the signal, magnitudes of variation amounts of acceleration per unit time generated in the vibratory device are different from each other. The signal control unit exerts the change from the reference level to the first level and the change from the first level to the reference level on the signal.

Devices, systems and methods for communicating to another user or users through skin response technology are provided. The present disclosure provides for receiving at least one message over a network by a mobile device; transmitting the received at least one message to a vibrotactile device configured to be worn on the skin of a user; converting, by the vibrotactile device, the transmitted at least one message into a predefined vibration pattern; and effecting the predefined vibration pattern onto the skin of a user by at least one actuating element of the vibrotactile device.

In one aspect, an apparatus includes a housing, a haptic element on at least a portion of the housing that has a non-discrete configuration and at least a first discrete configuration, a processor, a touch-enabled display operatively coupled to the processor, and a memory accessible to the processor. The memory bears instructions executable by the processor to initiate a function at the apparatus, and at least in part in response to initiation of the function, actuate a portion of the haptic element.

There is presented a system and method for providing real-time object recognition to a remote user. The system comprises a portable communication device including a camera, at least one client-server host device remote from and accessible by the portable communication device over a network, and a recognition database accessible by the client-server host device or devices. A recognition application residing on the client-server host device or devices is capable of utilizing the recognition database to provide real-time object recognition of visual imagery captured using the portable communication device to the remote user of the portable communication device. In one embodiment, a sighted assistant shares an augmented reality panorama with a visually impaired user of the portable communication device where the panorama is constructed from sensor data from the device.

An interactive braille display system includes a processor and a display unit in electronic communication with the processor. The display unit includes a braille cell unit and an interactive unit in physical contact with the braille cell unit. The interactive unit includes a surface layer for displaying braille information and sensing tactile contact by a user. The interactive unit also includes a subsurface layer in physical communication with the surface layer, the subsurface layer including electrodes for detecting a capacitance change caused by the tactile contact by the user. The capacitance change corresponds to a position of the tactile contact by the user.
