휴대용 전자제품 가상시작을 위한 능동적 감지 기반 감각형 상호작용 방안

Abstract

This paper presents an active sensing based tangible interaction for virtual prototyping of portable consumer electronic (PCE) products. The basic idea is to use an active sensing unit (ASU) that helps the operation of a virtual product model in a VR environment. The ASU is devised to perceive its orientation and user inputs and to send them a VR engine. Bluetooth module is used for wireless communication between the ASU and the VR engine. Users can create input events by touching specified buttons of the ASU and change the orientation by slowly rotating the body of the ASU. In addition, users can translate and scale the virtual product model by manipulating the joystick of the ASU. For realistic visualization, we adopt dual stereo rendering to create stereoscopic images of the virtual product model. For functional behavior simulation, we adopt state transition methodology to capture the functional behavior of the product into an information model, and build a finite state machine (FSM) to control the transition between states of the product based on the information model. The FSM is combined with the manipulation of the ASU to facilitate the realistic visualization and functional simulation of the PCE product in the VR environment. Based on the proposed interaction, a simple virtual prototyping system has been developed and applied for the design evaluation of various PCE products with encouraging feedbacks from users.
