What is a sense?

What modes do we use in interaction? Which others could we use? Objectives What modes do we use in interaction? Which others could we use? Why? How?

Some practical(?) possibilities Sounds Haptics Smell

Sounds Speech Non-speech synthesized earcons auditory icons sonification data mapping audification programs

Sounds Why do we not make more use of sounds in interfaces?

Haptics - definitions http://www.dcs.gla.ac.uk/~stephen/papers/CHI2000.pdf Term Definition Proprioceptive Relating to sensory information about the state of the body (including cutaneous, kinesthetic, and vestibular sensations). Haptic Relating to the sense of touch. Vestibular Pertaining to the perception of head position, acceleration, and deceleration Kinesthetic Meaning the feeling of motion. Relating to sensations originating in muscles, tendons and joints Cutaneous Pertaining to the skin itself or the skin as a sense organ. Includes sensation of pressure, temperature, and pain. Tactile Pertaining to the cutaneous sense but more specifically the sensation of pressure rather than temperature or pain. Force Feedback Relating to the mechanical production of information sensed by the human kinesthetic system.

smells Why do we not make more use of smells in interfaces?

Conclusions Why do we not make more use of other senses/channels/modes in interaction? Which ones could we practically use more? What would be the benefits?
