The Improvement and Evaluation of an Analog Digital Television System’s Availability and Users Experience

Abstract

Based on the RGBD sensor, this passage suggested a method named ‘Control-right Management’ to reduce the Interaction Information in order to bring better communication efficiency of an Analog Digital Television System. This system was base on fingertip, dynamic and static hand gesture recognition,and it can be controlled by person in the mid-air. And then split and recombination of different operation elements as “Complex Group Gesture” to improve the system’s availability and users experience. According to the Goals Operators Methods Selection Rules(GOMS) model we analyzed the operation step by step and found the redundant process, then reduce the operation time and steps to give the users better availability and users experience. Calculated by the formula of interaction efficiency, the changed operation showed more efficient than before.Finally we take some experiments of our methods and propose several specialize quantitative evaluation methods that can be used in the field of Digital Television System.
