- Independently refreshable pins in a 60×40 array
- Cursor pad for Navigation, and an SD-card slot
Graphiti is an Interactive Tactile Graphics Display based on revolutionary Tactuator technology from Orbit Research. It represents a breakthrough in non-visual access to any form of graphical information such as charts, drawings, flowcharts, floorplans, images and photographs, through an array of moving pins.
The Tactuator technology provides the ability to set each pin to different heights, which enables the display of topographical maps and other graphical elements such as grey shades and color represented as varying heights of pins that can be readily sensed by the user’s fingers.
Graphiti features a touch interface to enable the user to “draw” on the display; tracing a shape with a fingertip raises the pins along the path traced. The touch interface allows traditional forms of touch commands such as scrolling, multi-touch gestures such as pinch-to-zoom, etc. In addition, it enables novel uses such as “pushing” or “nudging” an object on the display to physically move it.
It is connectable to computers, tablets, smartphones, or the Orion TI-84 Plus Talking Graphing Calculator via a USB-C port or Bluetooth. Its open API allows developers to create apps to work with Graphiti. Additionally, an HDMI port allows connection to any device with a video display output. This enables any device to connect seamlessly to Graphiti. The unit also includes a cursor pad for navigation, and an SD-card slot for loading files for reading and editing in a standalone mode.
The proprietary technology is fundamentally scalable and enables development of refreshable graphic displays of any size, at a fraction of the cost of graphic displays in the market today. The first Graphiti model has 2,400 pins in an array of 60 x 40 pins, and can be used in a portrait or landscape orientation. Each pin is independently addressable and can also be made to individually “blink” at configurable rates.
Graphiti is expected to ship in late 2019. The picture shown is a one-quarter size prototype.
