Buttons when you need them.
Gone when you don’t.
Tactus provides a new dimension of user interface with a fundamentally unique solution: application-controlled, completely transparent physical buttons that rise up from the touch-screen surface on demand. With the buttons enabled, users can push and type or rest their fingers as they would with any physical button or keyboard. When the buttons are disabled, they recede into the screen, becoming invisible and leaving a smooth, seamless flat touch-screen with maximum viewing area.
How does this technology fit into the display stack?
Tactus’ technology readily integrates with capacitive touchscreens. The Tactile Layer replaces the top-most layer in the optical stack, often referred to as the window or cover lens. The thickness is designed to match the layer that it replaces. The Tactus layer is compatible with all type of touchscreen stack-ups.
The underlying technology that enables the Tactile Layer is called microfluidics. Small fluid channels are routed throughout the Tactile Layer and enable fluid to expand the top polymer layer to create the physical buttons.
A small Tactile Controller is connected to the Tactile Layer, which controls the state of the buttons. The controller is intended to be interfaced via USB, SPI or I2C to a processor. A basic API is provided to allow for integrated software/application based control.
Buttons During the Flat State
• Completely invisible
• Seamless multi-touch (fingers and stylus)
Buttons During the Raised State
• Real touch
• <1 sec. transition • Detects rest vs. press • Consumes energy only in transition
With 17,000 mechanoreceptors in our hands, we were meant to be tactile beings.
