Exploring Multimodal Watch-back Tactile Display using Wind and Vibration
summary
A wrist-mounted prototype stacks a small fan and an LRA to deliver wind and vibration on the same 40 mm watch back, and four experiments test individual, simultaneous, and sequential combinations. Results show sequential combinations outperform others, achieving an information transfer up to 3.29 bits and transition-type recognition at 98.52%; wind stimuli are weaker and often dominated by vibration, and simultaneous/overlapped patterns drop accuracy substantially.
