Identification and Information Transfer of Multidimensional Tactons Presented by a Single Vibrotactile Actuator

Techniques designed to deliver information to users via the haptic channel often make use of multiple actuators spread over different body locations, sometimes employing multiple haptic modalities (e.g., vibration, skin stretch, temperature) in parallel. Instead, we sought to determine the information transfer capacity of a single vibrotactile actuator. To do so, we designed 90 multidimensional ta...
