“…The results from the experiments were clear: the haptic feedback significantly increased the task performance, the perceived presence and perceived social presence. These findings have been confirmed in later studies on collaborative multimodal interfaces [Burke et al 2006;Lee and Kim 2008;Moll and Sallnäs 2009;Nam et al 2008]. Lee and Kim [2008] investigated the influence of haptic feedback on remote navigation during tele-operation of a mobile robot.…”

“…They found that both task performance and perceived presence were significantly increased when haptic feedback was added to a visual interface. Nam et al [2008] developed and evaluated an air-hockey game based on vision, haptic and audio. They let pairs of users compete in the game in a visual, visual/haptic, and visual/haptic/audio condition.…”

In the study presented here, two haptic and visual applications for learning geometrical concepts in group work in primary school have been designed and evaluated. The aim was to support collaborative learning among sighted and visually impaired pupils. The first application is a static flattened 3D environment that supports learning to distinguish between angles by means of a 3D haptic device providing touch feedback. The second application is a dynamic 3D environment that supports learning of spatial geometry. The scene is a room with a box containing geometrical objects, which pupils can pick up and move around. The applications were evaluated in four schools with groups of two sighted and one visually impaired pupil. The results showed the support for the visually impaired pupil and for the collaboration to be satisfying. A shared understanding of the workspace could be achieved, as long as the virtual environment did not contain movable objects. Verbal communication was crucial for the work process but haptic guiding to some extent substituted communication about direction. When it comes to joint action between visually impaired and sighted pupils a number of interesting problems were identified when the dynamic and static virtual environments were compared. These problems require further investigation. The study extends prior work in the areas of assistive technology and multimodal communication by evaluating functions for joint haptic manipulation in the unique setting of group work in primary school.

“…With modern haptic feedback equipment such as the point-based PHANToM-device used in the study presented in this paper, it is possible to simulate complex shapes, texture, friction, forces, weight and inertia. Studies have shown that task performance, as well as the sense of presence and awareness, can improve significantly when haptic feedback is added to a visual interface [30,36,45].…”

In this paper we present a study on the effects of auditory-and haptic feedback in a virtual throwing task performed with a pointbased haptic device. The main research objective was to investigate if and how task performance and perceived intuitiveness is affected when interactive sonification and/or haptic feedback is used to provide real-time feedback about a movement performed in a 3D virtual environment. Emphasis was put on task solving efficiency and subjective accounts of participants' experiences of the multimodal interaction in different conditions. The experiment used a within-subjects design in which the participants solved the same task in different conditions: visual-only, visuohaptic, audiovisual and audiovisuohaptic. Two different sound models were implemented and compared. Significantly lower error rates were obtained in the audiovisuohaptic condition involving movement sonification based on a physical model of friction, compared to the visual-only condition. Moreover, a significant increase in perceived intuitiveness was observed for most conditions involving haptic and/or auditory feedback, compared to the visual-only condition. The main finding of this study is that multimodal feedback can not only improve perceived intuitiveness of an interface but that certain combinations of haptic feedback and movement sonification can also contribute with performance-enhancing properties. This highlights the importance of carefully designing feedback combinations for interactive applications.

“…The Puck, Mallet and game field are displayed by a Head Mounted Display (HMD) that can provide realistic visual effects. Arkansas university developed an Air Hockey based on haptic device and monitor [6] as in Fig.2. In this system, Mallet can be preciously controlled as user's wish and Puck is displayed at a high refresh rate.…”

This paper shows the simulating and displaying of Puck motion in virtual Air Hockey based on projective interface for multi-users HRI. Image-projective Desktop Arm Trainer (IDAT) is an upper-limb rehabilitation system for hand-eye coordination training based on projective interface. To expand more entertainment functions and realize multi-user HRI, we want to develop a virtual Air Hockey application in IDAT. To develop this application, Puck motion should be simulated correctly and displayed smoothly on the screen. There are mainly 3 problems: Data updating rate problem, virtual collision calculation and individual's hand misrecognition problem. We proposed our method into three parts corresponding to different problems. In part 1, we used multiple timers with shared memory to deal with unsynchronized data updating rate problem. In part 2, an original physical engine is designed to calculate Puck's velocity and detect virtual collision. In part 3, to deal with the individual's hand misrecognition problem, a history-based hand owner recognition algorithm is implemented to distinguish users' hands.978-1-4673-9675-2/15/$31.00 © 2015 IEEE
