Sampling Strategy for Ultrasonic Mid-Air Haptics

Explore a conference talk on ultrasonic mid-air haptics sampling strategies presented at the ACM CHI Conference on Human Factors in Computing Systems. Delve into the impact of hardware update rates on tactile pattern perception, challenging the assumption that higher rates always improve experience. Examine two user studies investigating perceived strength and optimal update rates for various pattern sizes. Discover how update rate should be considered an additional parameter in tactile pattern design. Learn about localized mutation techniques, lateral modulation, and animated mutation in mid-air haptics. Gain insights into the researchers' methodology, including rating systems, graphing techniques, and quadratic modeling. Understand the implications for future work and potential implementation in designer tools to simplify the complexity of mid-air tactile displays.
