Design Method of UI of AV Remote Controller Based on AHP

Abstract

This paper proposes a new model for designing the User Interface of an Audio-Visual remote controller based on an Analytic Hierarchy Process. This model has the goal of switching the Ut of the controller to one optimized for each user. The following four criteria were defined; Demographic, Geographic, Psychographic and Activity. Sensor and I/O, Visual, Functional and Interaction interfaces were selected as the alternatives. Next, the method of selecting the most suitable Ut for each user by using the proposed model based on AHP is described and shown by an example. Finally, the implementation of the proposal into a verification system for an AV remote controller using an embedded microprocessor for consumer use is described. I. INTRODUCTIONA traditional audio visual (AV) remote controller and its user interface (UI) have the following problems. For example, remote controllers have irregular UI designs because each manufacturing corporation develops them in their own style and the necessary functions depend on the AV equipment. Most controller input interfaces are buttons and the number of buttons is nearly equal to the number of functions of the equipment. Additionally, the operation of an AV system requires the same number of remote controllers as the equipment in the system. Therefore, it is difficult to combine more than two devices and operate them at the same time by using only one controller in operations such as dubbing. The user should consider the input procedures and operate the necessary equipment with the same number of remote controllers.The authors have previously proposed various methods of solving these problems [1][2][3]. However, these methods are based on conventional design concepts and do not consider the user's operation ability and the system configuration.Therefore, this paper proposes a new method of designing the UI for an AV remote controller based on an analytical hierarchy process (AHP) [4]. Next, an evaluation method of each user's UI evaluation method is shown. Finally, the method is implemented into an AV remote controller prototype and is verified.

Suitable GUI selection using analytic hierarchy process

“…The authors have proposed some design strategy models on user interface of AV remotes [1,2]. However, these targeted general users interface (UI) and have not discussed special alternatives for Graphical User Interface (GUI).This study proposes solving this problem by changing the GUI of a multiwireless remote controller.…”
