A case study of phantom omni force feedback device for virtual product design

Abstract

Research towards a methodology which helps designers/engineers in conceptualizing, facilitating participatory Design and validating products during designing and development process becoming more important with the aim of reducing the lengthy process and errors that crops up during the process. In this kind of situation it is felt that Virtual Reality-Haptic is among the solutions to cater repeated physical prototyping as well as for rapid prototyping and reduces related cost. This integrated system of virtual reality-Haptic feedback interaction may enhance the usability evaluation of virtual products. Therefore, emphasis of this paper is to study the virtual and augmented reality, Haptics working principles and their advantage towards product evaluation. Through this study it was possible to understand the working principles of Haptic device and write codes/program using OpenHaptics Software development Toolkit in order to manipulate the virtual object which was prepared through CAD Software (in this research CATIA was used), thereafter, experimental setup with full system were established. After preparing questionnaires and virtual reality-haptic system, participants were allowed to manipulate the virtual object via phantom Omni haptic feedback device and compare the physical properties of different virtual objects. Finally collected data were analyzed and drawn a result that revealed the potential of Virtual Reality-Haptic system for realizing the virtual objects surface texture, size, shape, and weight.

A UNITY Sketch Based Modelling Environment for Virtual Assembly and Machining to Evaluate DFMA Metrics

“…This device allows 6DOF input for the user and provides 3DOF haptic feedback, providing the user with a sense of weight, surface texture stiffness and 3D shape. This has been shown to be useful for the design of products in virtual space [40].…”

Haptic‐based virtual reality simulator for lateral ventricle puncture operation

“…The collision information between the virtual cursor and the virtual brain model is transmitted to the haptic device through the serial interface, driving the motor to generate torque, and finally acting on the end handle. 21 Therefore, the trainer operates the haptic device to control the virtual surgical instrument and feel haptic feedback. The Side-Distance is less affected by the curvature of the scalp due to the small distance from the midline of the brain.…”

Conceptualization and Research Progress on Web-Based Product Co-Design

“…Methods of sharing product representations over the virtual environment and a number of CAD-integrated shared workspaces have been presented in the scientific literature for distributed design review [70,71]. Other relevant studies include virtual and augmented reality, haptics working principles and their advantage towards product evaluation [72,73], web 3D-based collaborative design research [74], etc.…”
