“…Practical considerations, but also financial and operational constraints, limit the degree to which sensory stimuli can be provided in many applications [ 13 ]. While there, for example, is progress in providing haptic cues [ 1 – 4 , 14 – 26 ] there still are significant challenges [ 14 , 27 ] that can make some tasks more difficult and decrease overall task efficiency [ 15 ] when haptic cues are presented.…”

Objective and subjective measures of performance in virtual reality environments increase as more sensory cues are delivered and as simulation fidelity increases. Some cues (colour or sound) are easier to present than others (object weight, vestibular cues) so that substitute cues can be used to enhance informational content in a simulation at the expense of simulation fidelity. This study evaluates how substituting cues in one modality by alternative cues in another modality affects subjective and objective performance measures in a highly immersive virtual reality environment. Participants performed a wheel change in a virtual reality (VR) environment. Auditory, haptic and visual cues, signalling critical events in the simulation, were manipulated in a factorial design. Subjective ratings were recorded via questionnaires. The time taken to complete the task was used as an objective performance measure. The results show that participants performed best and felt an increased sense of immersion and involvement, collectively referred to as ‘presence’, when substitute multimodal sensory feedback was provided. Significant main effects of audio and tactile cues on task performance and on participants' subjective ratings were found. A significant negative relationship was found between the objective (overall completion times) and subjective (ratings of presence) performance measures. We conclude that increasing informational content, even if it disrupts fidelity, enhances performance and user’s overall experience. On this basis we advocate the use of substitute cues in VR environments as an efficient method to enhance performance and user experience.

“…In order to allow users' immersion in the virtual world and assist him/her in the 3D layout task, a human-scale VR platform with haptic feedback is used (Fig.1). This platform provides haptic cues using a string-based force feedback interface (Richard et al, 2006). Stereoscopic images are displayed on a rear-projected large screen and are viewed using polarized glasses.…”

Virtual Reality (VR) is a promising tool for effectively visualizing and interacting with objects and 3D environments. However, Virtual Environments (VEs) should provide some assistance to help the users in complex solving tasks. We aim to combine VR and Constraint Programming (CP) techniques in order to assist the users in realizing 3D objects layout in restricted spaces. The proposed approaches are based on a tight communication between a 3D rendering module and a highly efficient constraint solver. Layout modification are translated in incoming queries to the solver which generates the solutions that satisfy predefined constraints. In order to achieve users' immersion in the VE and intuitive manipulation of the objects, a human-scale VE platform with haptic feedback is used. In this paper, we focus on the system architecture and we describe the implementation of simple constraints. Finally, some results based on geometric constraints are presented.

In this paper, we describe innovative approaches for the design of intelligent virtual environments (VE) for interactive problem solving. Thus, we propose to extend VEs to support constraint-based interaction through the use of Constraint Programming (CP) techniques. The aim of this paper is to argue for the need of CP integration in VEs and its high relevance in the 3D-objects layout problem. The user manipulation will be translated as incoming queries of the intelligent module (solver) which will generate a solution compatible with the design requirements. Thus, the task of the solver is to satisfy the constraints specified by the system in response to user interaction. In order to exhibit a high degree of visual richness and realism, the use of human-scale multi-modal 3D interaction techniques and tools is proposed.
