The present disclosure relates to tactile displays, for example electro-magnetic Braille displays. In certain disclosed embodiments, tactile displays may comprise capture plate assemblies. Such capture plate assemblies may be removable from tactile displays to facilitate cleaning and/or maintenance of the tactile display.

Capture plate assembly for braille display

An adapter for a tactile display is disclosed. The adapter can be used with a tactile display, such as a display that presents braille characters, to change or modify what is presented to a user. In some embodiments, the braille dots which make up a braille character can be made smaller or larger; spaced closer together or further apart; have a different shape; and/or an image or non-braille characters can be presented to a user of the tactile display using the disclosed adapter.

RFID tag in display adapter

A system for providing a tactile display is disclosed. The system utilizes magnetic forces and actuators in order to move a series of tactile elements. The system can be arranged such that the display may include an entire array of thousands of elements.

Refreshable tactile display

A system and methods are disclosed to facilitate communication to, with, and for persons with special needs. The system can provide assistance with reading, test-taking, language development, or other forms of communication. The system is compatible with a variety of types of input (), and provides a variety of options for output (). In one embodiment, the system is portable, and can be connected to a number of different devices having varying purposes. In another embodiment, the system is software designed to be utilized as a stand-alone software application, or in conjunction with an existing or third-party application.

Content communication system and methods

DEAF-core technology converts inputs to outputs accessible to people with disabilities. Communication is improved with DEAF-core technology by using data storage and transmission format that includes both semantic information and content. User-defined input, responsible for conveying semantic information, and raw analog input, such as text, are converted into a unique XML format ('gh XML'). 'gh XML' includes standard XML encoded with accessibility information that allows a user to communicate both verbal (text) and non-verbal (semantic) information as part of the input. &#x201c;gh XML&#x201d; is a temporary format which is further converted using XSLT (extensible Stylesheet Language Transformations) into individual versions of XML specific to each output. After the &#x201c;gh XML&#x201d; is converted into the desired XML format, custom rendering engines specific to the desired output convert the individual version of XML into a viable analog format for display.

Universal processing system and methods for production of outputs accessible by people with disabilities

Various apparatus and methods for an actuator and display using one or more shape memory springs. A shape memory spring is heated and urges a pin to a first or extended position. The pin may be supported in the first position by a supporting mechanism. The shape memory spring is heated electically, and in some embodiments under the control of a processor. The present invention may be used to display information provided in a user interface from a computer program, including text, numerical data, and graphical images.
