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 drum pedal sensing system may include a base, a foot board, a pedestal, a beater, beater stem, and beater holder operatively connected to the foot board, a sensor holder, and a sensor fixedly coupled to the sensor holder. The beater holder may include a sensing surface that may rotate as the foot board is depressed and that may remain a substantially constant distance from the sensor as the sensing surface rotates. Additionally, the system may include a microprocessor operatively coupled to the sensor that receives signals from the sensor corresponding to motion of the sensing surface. Based on sensed changes such as changes in position, velocity, or acceleration, the microprocessor may determine whether the beater has contacted a drum face and, if so, may send an output signal to a stomp box, drum brain or similar element, with the amplitude of this output signal proportional to strength of the hit.

A mail sorter ( ) includes an imaging device ( ) to generate a plurality of images each corresponding to one of the plurality of mail pieces ( ). The mail sorter ( ) performs a character recognition routine on each of the images to sort a number of the mail pieces ( ) and identify one of the mail pieces as being unsortable by the routine. An operator input processing subsystem ( ) includes a number of stations ( ). These stations ( ) each include a display and a voice input device. The subsystem ( ) responds to the mail sorter ( ) to route the images to the stations ( ). One of the stations ( ) is operable to display one of the images on its corresponding display device and receive vocal input from an operator with its corresponding voice input device in response to viewing the image. The subsystem ( ) executes a voice recognition routine to determine address information from the vocal input and provides this information to the mail sorter ( ) to sort a corresponding one of the mail pieces ( ).
