Simulation exercises have an established history across various professions. Flight simulators
have long been used for military, aircraft, and NASA training, and driving simulators have been used
for driver's education. Vitual worlds simulate real-world conditions, placing people in situations
that test their response time, decision making, or interactions. Students of medicine and physical
or occupational therapy commonly spend time in wheelchairs or blindfolded to empathically experience the
patient's world or restricted mobility or visual impairment. The intent of simulation exercises for
design research teams is to likewise form a tangible sense of user empathy, influencing design
sensitivity and decisions through direct although simulated experience.
