  • Patent number: 8866774
    Abstract: Tactile feedback for touch screens is provided by an overlay structure disposed on the top surface of the touch screen. This overlay structure can be in either of two states. In the first state (non-typing), the overlay structure has a uniform top surface. In the second state (typing), the overlay structure top surface has localized regions of increased vertical elevation to provide tactile feedback for typing. The overlay structure is configured to be switched between these two states by actuator(s) disposed to provide mechanical force(s) in lateral direction(s) to the overlay structure. Preferably, the actuator is a latching actuator (e.g., magnetic solenoid) that does not consume power to hold the overlay structure in either of its states. Thus, power is only consumed to switch the state of the overlay structure.

  • Publication number: 20140065579
    Abstract: An improved Braille erasure mechanism may comprise a reverse-embosser or impressing mechanism to imprint a negative Braille cell. A negative Braille cell is the reverse of a normal Braille cell, with one or more dots lowered or pressed into the printing medium in an opposite direction to the raised dots of a normal Braille cell. Because the dots of a negative Braille cell are lowered past the surface of the printing medium, they may be ordinarily undetectable to the fingers of a Braille user. Accordingly, by imprinting a full negative Braille cell on top of a Braille cell to be erased, all of the previously raised dots of the Braille cell may be lowered beyond the surface of the printing medium. Any further Braille cell embossed over the erased cell will be free from corruption, because any dot not used by the new cell will remain lowered and undetectable.

  • Patent number: 8602787
    Abstract: An improved Braille erasure mechanism may comprise a reverse-embosser or impressing mechanism to imprint a negative Braille cell. A negative Braille cell is the reverse of a normal Braille cell, with one or more dots lowered or pressed into the printing medium in an opposite direction to the raised dots of a normal Braille cell. Because the dots of a negative Braille cell are lowered past the surface of the printing medium, they may be ordinarily undetectable to the fingers of a Braille user. Accordingly, by imprinting a full negative Braille cell on top of a Braille cell to be erased, all of the previously raised dots of the Braille cell may be lowered beyond the surface of the printing medium. Any further Braille cell embossed over the erased cell will be free from corruption, because any dot not used by the new cell will remain lowered and undetectable.

  • Publication number: 20130316312
    Abstract: The present invention includes a flat face, a dots raising mechanism, a display cell, a first column, a second column, an interface, and a connection port. The first column includes a first dot, second dot, and a third dot while the second column includes a fourth dot, a fifth dot, and a sixth dot. The columns are on the display cell. The display cell is capable of displaying a single Braille character. To convey information from a text source, the display cell raises and lowers the dots, successively forming different characters. A first time interval, a second time interval, and a third time interval help differentiate the first column from the second column, a first character from a following character, and a first word from a following word. The time intervals simulate physical space between and with the cells found in printed Braille.

  • Patent number: 8573979
    Abstract: A tactile display may comprise an array of pins that may be raised in height relative to one another to represent contours of objects in a graphic image or picture when touched. Various physical attributes may be given to individual pins to represent color or brightness. For example, pins may be heated or cooled to represent cool or warm colors in the original image. Pins may also be vibrated or otherwise enhanced to represent color or brightness information in the original image.

  • Patent number: 8502651
    Abstract: A game is provided on one or more portable computing device in which a virtual object travels through views of the game displayed on the interfaces of the one or more portable computing devices. Haptic effects corresponding to the travel of the virtual object through the views are provided on the individual portable computing devices. The haptic effects may be determined based on one or more parameters of the travel of the virtual object, one or more parameters of objects and/or features with which the virtual object interacts, and/or other parameters. The haptic effects may include haptic effects to be provided on portable computing devices that are not currently displaying the virtual object corresponding to the haptic effects.

  • Publication number: 20130164717
    Abstract: A Braille display system and a method for operating a refreshable Braille display 14 is provided. A string of characters is assigned to a drive signal for specifying the activation or deactivation of a tuple of dots which are raised through holes in a touch and sense surface of the Braille display 14 upon activation and which are retracted upon deactivation. The Braille display 14 is driven by a drive signal which is configured to activate and/or to deactivate the tuple of dots so as to generate a dynamic tactile display of said string of characters. The time dependent characteristic of activation and/or deactivation of the tuple of dots is defined by the string of characters.

  • Patent number: 8451248
    Abstract: Disclosed is a display device that provides a user with tactile feedback using a tactile user interface. The display device includes a touch sensitive display unit to display an object, a tactile feedback unit to generate tactile feedback, and a controller. The controller detects a first touch that is in contact with a region of a first object displayed on the display unit, detects a second touch controlling the first object that is consecutive to the first touch, controls the first object in response to the second touch, generates first tactile feedback according to properties of the first object in response to the second touch, detects a third touch controlling the first object that is consecutive to the second touch, the third touch being detected in a region of a second object displayed on the display unit, and generates the first tactile feedback in response to the third touch.
