To facilitate the development of a new home-entertainment device (a portable projector with built-in speakers and a DVD player) we conducted in-home interviews that explored home entertainment activities, presented a demo of a rough prototype, and brainstormed with participants about future refinements.Our research revealed that people use TV in a variety of ways, from special events to background noise. Although the device was intended only to support special event viewing (being brought out for special events and then stored when not in use) we found that the unrefined nature of the prototype led respondents to expect that the eventual product would support any and all of their TV usage modes,The critical recommendation was that if (as planned) the final product would not support those viewing modes, it must be crystal clear (through a consistent story of design, pricing, and features) how it can and can't be used.
