Design Evaluation System with Visualization and Interaction of Mobile Devices Based on Virtual Reality Prototypes

Abstract

In this paper, we present a design evaluation system with visualization and interaction of mobile devices using virtual‐reality‐based prototypes which can be used to easily change design parameters and simulate embedded software. To evaluate and predict affective‐engineering‐based design preferences for mobile devices under a virtual environment, we have developed a high quality visualization platform which creates images that look similar to real mobile devices in addition to real‐time simulation of realistic motions and functions of mobile devices. To support a quantitative usability test scenario for external design shape, we also have built a system which consists of a mixed‐reality‐based testing platform for measuring hand load.

Welding representation for training under VR environments

“…The shape of beads through user's operations showed up great differences depending on all static (e.g., current, voltage) and dynamic variables (e.g., torch distance, work angle, travel angle, torch speed). We also developed realistic visualization of the bead's shape, which is included to represent photo-realistic rendering of bead appearance using GPU based shading language as shown in Fig 6 [ Jo et al 2008;Yang et al 2010]. We also implemented visualization of the filter blocking situation under wearing welding mask with light control and special effects such as arc and spark using texture animation and particle.…”

Tracking and Interaction Based on Hybrid Sensing for Virtual Environments

“…In addition, as an essential factor for interaction under virtual environments, tracking technology placed on body parts, including the hands, is being consistently developed [1], [2].

Tracking and Interaction Based on Hybrid Sensing for Virtual Environments

“…In addition, as an essential factor for interaction under virtual environments, tracking technology placed on body parts, including the hands, is being consistently developed [1], [2]. Markerless-based tracking with depth sensors is useful for user interaction in virtual reality systems and is helpful in the effort to overcome the inconvenience of wired interface devices and attached markers used in tracking in magnetic and optical methods.…”
