Direct Memory Access in circular mode enables continuous waveform generation with zero CPU overhead. The DMA controller automatically transfers phase data to timer registers at 40kHz.
3000Hz control loop ensures smooth haptic rendering. Phase updates are synchronized with the carrier frequency for precise acoustic focusing.
From automotive to healthcare, mid-air haptics is redefining human-machine interaction.
Gesture control without contact. Drivers can interact with infotainment systems through mid-air haptic feedback, reducing visual distraction.
Tactile feedback in virtual environments. Feel virtual objects, textures, and interactions without wearing gloves or holding controllers.
Sterile interface interaction. Surgeons and medical staff can control equipment without touching surfaces, maintaining sterile fields.
HMI for cleanroom environments. Operators can interact with control systems without introducing contaminants or wearing special equipment.
