Holographic Keyboard HoloType Goes Commercial: Typing in Thin Air Becomes Reality
German startup HaptiType's HoloType holographic keyboard uses laser projection and focused ultrasound to enable typing in mid-air at 60 words per minute, with initial deployments in airport lounges and sterile medical environments.
German startup HaptiType officially released its holographic keyboard HoloType in June 2028. The device projects a virtual keyboard onto any surface via laser while using infrared light curtains to detect finger positions and focused ultrasound to deliver haptic feedback at the fingertips.
HoloType achieves 60 words per minute with approximately 92% accuracy in testing — lower than physical keyboards' 98% but exceeding most touchscreen virtual keyboards.
HaptiType CEO Friedrich Muller said: "HoloType solves the space problem. When your desk can't fit a keyboard, or you can't use physical devices in sterile environments, typing in thin air is the only option."
Initial commercial deployments include Lufthansa airport lounges and Berlin's Charite Hospital, where surgeons use HoloType to operate medical systems without removing gloves. The device is priced at 1,299 euros.
