Spoken Help for a Car Stereo: An Exploratory Study
This chapter reports an investigation of the use of spoken (audible) help in an attempt to increase the usability and learnability of a high-end (i.e. relatively expensive, multifeatured) car stereo. To investigate the usefulness of audible spoken help for a car stereo, a simulation was constructed within which experimental help systems were incorporated. To validate the simulation, the ' real' car stereo (an existing consumer product, acting as the control condition) was compared empirically with its simulation.
