“…Haptic interfaces were shown to greatly enhance interaction with Virtual Environments (VE) [1,2]. Most of the current haptic interfaces are well suited for "desktop" applications, in which the dimensions of the visual display of the virtual environment do not exceed the size of the haptic workspace of the manipulated device.…”

Abstract. This paper describes an experiment that was conducted to evaluate three interaction techniques aiming at interacting with large virtual environments using haptic devices with limited workspace: the Scaling technique, the Clutching technique, and the Bubble technique. Participants were asked to paint a virtual model as fast and as precisely as possible inside a CAVE, using a desktop haptic device. The results showed that the Bubble technique enabled both the quickest and the most precise paintings. It was also the most appreciated technique.

“…Research has shown that the addition of force feedback to virtual environments increases task efficiency times [21,22]. Also, testing on subjects has verified that operators feel more secure and can relate better to the real world processes when trained on a simulator with haptic feedback than those trained on a simulator with no haptic feedback [23]. Since most haptic devices require a high update rate to guarantee force continuity, the real challenge is to maintain haptic update rate especially when interacting with large CAD models.…”

Virtual Reality (VR) technology holds promise as a virtual prototyping tool for mechanical assembly; however, several developmental challenges still need to be addressed before virtual prototyping applications can successfully be integrated into the product realization process. This paper describes the development of SHARP (System for Haptic Assembly & Realistic Prototyping), a portable VR interface for virtual assembly. SHARP uses physically-based modeling for simulating realistic part-to-part and hand-to-part interactions in virtual environments. A dual handed haptic interface for realistic part interaction using the PHANToM® haptic devices is presented. The capability of creating subassemblies enhances the application's ability to handle a wide variety of assembly scenarios. Swept volumes are implemented for addressing maintainability issues and a network module is added for communicating with different VR systems at dispersed geographic locations. Support for various types of VR systems allows an easy integration of SHARP into the product realization process resulting in faster product development, faster identification of assembly and design issues and a more efficient and less costly product design process.

“…Force cues provided by haptics technology can help designers feel and better understand the virtual objects by supplementing visual and auditory cues and creating an improved sense of presence in the virtual environment [108][109][110]. Research has shown that the addition of haptics to virtual environments can result in improved task efficiency times [111,112].…”

Assembly planning and evaluation is an important component of the product design process in which details about how parts of a new product will be put together are formalized. A well designed assembly process should take into account various factors such as optimum assembly time and sequence, tooling and fixture requirements, ergonomics, operator safety, and accessibility, among others. Existing computer-based tools to support virtual assembly either concentrate solely on representation of the geometry of parts and fixtures and evaluation of clearances and tolerances or use simulated human mannequins to approximate human interaction in the assembly process. Virtual reality technology has the potential to support integration of natural human motions into the computer aided assembly planning environment (Ritchie et al. in Proc I MECH E Part B J Eng 213(5): [461][462][463][464][465][466][467][468][469][470][471][472][473][474] 1999). This would allow evaluations of an assembler's ability to manipulate and assemble parts and result in reduced time and cost for product design. This paper provides a review of the research in virtual assembly and categorizes the different approaches. Finally, critical requirements and directions for future research are presented.
