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.

Smartphone-like or TV-like Smart TV?: The Effect of False Memory Creation
TVX '18: Proceedings of the 2018 ACM International Conference on Interactive Experiences for TV and Online VideoFalse belief pertains to what users believe falsely in their mental model about remembering novel features with no prior experience. The current study investigated how the False Belief technique can be employed to extract a first-time smart TV user's ...
Remember/know judgments probe degrees of recollection
Remembering and knowing are states of awareness that accompany the retrieval of facts, faces, and experiences from our past. Although originally intended to separate episodic from semantic memory, the dominant view today is that recollection-based ...

Event-related fMRI studies reveal that episodic memory retrieval modulates lateral and medial parietal cortices, dorsal middle frontal gyrus (MFG), and anterior PFC. These regions respond more for recognized old than correctly rejected new words, ...
