This novel wearable provides touchless haptic feedback for VR typing
- UltraBoard is a novel wearable developed by researchers at KAIST’s HCI Tech Lab for VR typing, providing touchless haptic feedback.
- The device uses an array of ultrasonic transducers to produce strong soundwaves that users can feel but not hear, targeting specific points while typing in virtual reality.
- UltraBoard straps onto each wrist, with a servo motor tilting the transducer array to match the wrist angle, ensuring it's always beneath the hand.
- The prototype device uses Arduino boards to control the transducer array and servo motor, following commands from a connected PC running VR software.
- Testing showed mixed results with no significant improvement in typing speed, but further testing may reveal additional benefits.
- The concept of UltraBoard offers an interesting approach to enhancing the VR typing experience.
- Fans prefer mechanical keyboards for their tactile feedback, which reduces strain and potential for repetitive strain injuries.
- This touchless haptic feedback technology aims to provide a similar tactile sensation experienced on mechanical keyboards.
- The UltraBoard device targets enhancing the VR typing experience without physical actuators for haptic feedback.
- Results indicate that UltraBoard did not result in a statistically significant increase in typing speed during testing.
- The wearable device utilizes ultrasonic transducers to project localized soundwaves for tactile sensations while typing.
- An array of ultrasonic transducers beneath the hand provides touchless haptic feedback during VR typing sessions.
- The UltraBoard device is positioned under the user's hand to ensure direct contact, controlled by a servo motor matching the wrist angle.
- Initial testing of UltraBoard displayed no significant enhancement in typing speed, but further benefits may emerge with additional trials.
- The concept of touchless haptic feedback for VR typing with UltraBoard aims to provide an innovative typing experience in virtual reality environments.
