Problem Representation What types of design problems are implicit interaction difficulties? We introduced implicit interactions by stating that they may be employed when the user is concentrated on something other than trying to get an interactive expedient to do what he or she wants; maybe because the user is physically, socially, or cognitively engaged, or because he or she is not knowing of what direction that the interaction should take. These are instances where the design requires some degree of agency on the part of the interactive system. That said, whether a design wants agency is a matter of the designer’s point of view. A car, for example, may be said to be driven through the direct handling of the steering wheel, gas, brake, and clutch pedals. However, one also can view the interaction between car and driver as a series of sometimes overlying communications—that the driver requests greater speed by pressing on the gas pedal, or a change in path by turning the steering wheel. This second view grows more apt as steer-by-wire technology for automobile operation becomes dominant. It may be senseless, from a design position, to speak of which view is right or wrong, but it is obvious that the adoption of different points of view suggests very different types of solutions. For this reason, it is useful to view the implicit interaction framework less as a hammer, and more as a lens. From the design research
