I Remember What I Saw in Your TV: A False ‘Belief’ Technique to Feature Selection

Abstract

This paper reports on the primary decision problem in the smart TV UI design -- features selection. The conventional feature selection methods were not able to render what features are to be included in the new TV design, and this position paper introduced the "False Belief technique" to extract a users' schema of the novel features from smart TVs. We found that this technique could effectively examine the users' mental model of the smart TV services, in a rather unconscious way at the expense of extra training time. Also, it can quantify utility values of the features so that the designer can prioritize what features should be firstly considered in a novel product development.
