The Natural Way of Gestures for Interacting with Smart TV
Jinhae Choi,Jiyoung Hong 대한인간공학회 2012 大韓人間工學會誌 Vol.31 No.4
Objective: The aim of this study is to get an optimal mental model by investigating user"s natural behavior for controlling smart TV by mid-air gestures and to identify which factor is most important for controlling behavior. Background: A lot of TV companies are trying to find simple controlling method for complex smart TV. Although plenty of gesture studies proposing they could get possible alternatives to resolve this pain-point, however, there is no fitted gesture work for smart TV market. So it is needed to find optimal gestures for it. Method: (1) Eliciting core control scene by in-house study. (2) Observe and analyse 20 users" natural behavior as types of hand-held devices and control scene. We also made taxonomies for gestures. Results: Users" are trying to do more manipulative gestures than symbolic gestures when they try to continuous control. Conclusion: The most natural way to control smart TV on the remote with gestures is give user a mental model grabbing and manipulating virtual objects in the mid-air. Application: The results of this work might help to make gesture interaction guidelines for smart TV.

In this study, MoS<sub>2</sub> combined CNW electrodes for supercapacitor application were fabricated to improve the electrochemical capacitive properties using hydrogen introduced remote ECR plasma without heating system. The source of MoS<sub>2</sub> was prepared from ATTM. The results revealed that crystallization of ATTM to MoS<sub>2</sub> can be achieved by hydrogen radicals without heating system. Enhancement of specific capacitance was achieved by MoS<sub>2</sub> synthesis on CNW structure from 2.6 mFcm at pristine CNW electrode to 3.3, 5.8 and 8.5 mFcm<sup>-2</sup> depending on MoS<sub>2</sub> concentration.
