Abstract
In this paper, we describe an interface for browsing and skipping digital video content in a consumer setting; that is, sitting and watching television from a couch using a standard remote control. We compare this interface with two other interfaces that are in common use today and found that subjective satisfaction was statistically better with the new interface. Performance metrics however, like time to task completion and number of clicks were worse.
Review
Traditional usability engineering techniques measure successful task completion, efficiency and error rate, parameters that are usually correlated positively with user satisfaction. Most notable among the recent findings about home infotainment devices is the realization that usersÂ’ subjective satisfaction is at odds with performance metrics. In a usability test of three video skipping interfaces (two commercial and one novel), users preferred the interface that required more time, clicks and had the highest error rate. Users reasoned their choice on the basis of how fun and relaxing an interface was.
