Haptic touch platform targets aerospace apps

HiWave Technologies unveils the Bending Wave, a haptics (touch feedback) platform for control panels and touch displays targeted at aerospace applications.

The integrated hardware/software platform enables systems designers to replace conventional mechanical buttons with touch switches, and bring haptic feedback to panels and displays so that users perceive the positive experience of mechanical movement, even though none is present.

For cockpit electronic systems, HiWave's Bending Wave touch/haptics provide greatly improved user feedback and safety than existing touch controls. The company's force-related haptics enable touch detection and tactile sensation from non-moving touch switch arrays, even with gloved hands.

As no mechanical movement is present there is no physical wear, reducing maintenance costs. HOTAS (Hands On Stick And Throttle) functions can be contextually mapped onto sensor arrays, and MHDDs (Multi-Function Head Down Displays) can have full multi-level touch and gesture recognition with 3D haptic response. Passenger aircraft in-flight entertainment systems benefit similarly from this patented haptic technology.

The evaluation platform incorporates HiWave's HIHXC14C02-8 or HIHXC09C005-8 haptic actuators, which attach to the touch interface panel or switch array. A HiWave haptic controller integrated circuit resolves touch input and delivers the haptic signals to the actuators.

HiWave's Bending Wave actuators create waveforms across the touch panel or switch, which may result to any of a range of switch sensations such as the feel of a mechanical switch or button. The company's algorithms processed in its haptic control chip enable feedback responses to be defined by the designer, and replicate a wide range of button or key-press sensations, or textures to convey information to the user.
