Tactile Echoes: Multisensory Augmented Reality for the Hand

Touch interactions are central to many human activities, but there are few technologies for computationally augmenting free-hand interactions with real environments. Here, we describe Tactile Echoes, a finger-wearable system for augmenting touch …

Contact forces in roughness discrimination

Roughness perception through fingertip contact with a textured surface can involve spatial and temporal cues from skin indentation and vibration respectively. Both types of cue may be affected by contact forces when feeling a surface and we ask …

Tactile Echoes: A Wearable System for Tactile Augmentation of Objects

We present Tactile Echoes, a wearable system for augmenting tactile interactions with any object. This system senses vibrations in the fingertip that are produced by interactions of the finger with a touched object. It processes the vibration signals …

The frequency of tactile adaptation systematically biases subsequent frequency identification

Exposure to a particular sensory stimulation for a prolonged period of time often results in changes in the associated perception of subsequent stimulation. Such changes can take the form of decreases in sensitivity and/or aftereffects. Aftereffects …
