“…The effects of haptic feedback on user performance have been documented in previous studies, e.g., [46,[56][57][58]65]. Other research has shown that haptic feedback improves user performance for 3D pointing in VR over no feedback [35,42]. Overall, these VR studies yield a broad indication that haptic feedback can increase user performance in VE [11,42], and further work has proposed to use haptic feedback as an assistance system [29,42].…”

A relatively recent application area for Virtual Reality (VR) systems is sports training and user performance assessment. One of these applications is eye-hand coordination training systems (EHCTSs). Previous research identified that VR-based training systems have great potential for EHCTSs. While previous work investigated 3D targets on a 2D plane, here we aim to study full 3D movements and extend the application of throughput analysis to EHCTSs. We conducted two user studies to investigate how user performance is affected by different target arrangements, feedback conditions, and handedness in VR-based EHCTSs. In the first study, we explored handedness as well as vertical and horizontal target arrangements, and showed that user performance increases with the dominant hand and a vertical target plane. In the second study, we investigated different combinations of visual and haptic feedback and how they affect user performance with different target and cursor sizes. Results illustrate that haptic feedback did not increase user performance when it is added to visual feedback. Our results inform the creation of better EHCTSs with mid-air VR systems.

“…Results in time performance indicate the Drag and Follow techniques had the greater amount of time elapsed by the users. This might be due that this techniques required pointing towards the desired contact area [28,32] and Fitts' Law [7,14,16,25] as shown in the research of Bruder et al [9] and Chun et al [22]. In addition, the presented shapes had also different levels of complexity in the coloring task.…”

Encountered-Type Haptic Displays (ETHDs) represent a field of haptic displays with the premise of not using any type of actuator directly in contact with the user skin, thus providing an alternative integration of haptic displays in virtual environments. In this paper, we present novel interaction techniques (ITs) dedicated to ETHDs. The techniques aim at addressing the issues commonly presented for these devices such as limited contact areas, lags and unexpected collisions with the user. First, our paper proposes a design framework based on several parameters defining the interactive process between user and ETHD (input, movement control, displacement and contact). Five techniques based on different ramifications of the design space framework were conceived, respectively named: Swipe, Drag, Clutch, Bubble and Follow. Then, a use-case scenario was designed to depict the usage of these techniques on the task of touching and coloring a wide, flat surface. Finally, a user study based on the coloring task was conducted to assess the performance and user experience for each IT. Results were in favor of Drag and Clutch techniques which are based on manual surface displacement, absolute position selection and intermittent contact interaction. Taken together our results and design methodology pave the way to the design of future ITs for ETHDs in virtual environments.

“…The HMD gave the worst result in both the experimental task and the SSQ assessment due to the accompanied discomfort and fatigue. Chun et al [6] considered that it may be due to its limited configuration where the resolution is only 800×600 pixels with a small field of view. In all conditions, movement time increased linearly with levels of IDs.…”

“…Fitts' pointing paradigm is a visually-controlled task, hence either input devices or display devices could influence performance of human motor system. In order to test whether Fitts' Law is applicable to compare display devices, Chun et al [6] used Fitts' Law to evaluate four 3D stereo displays with same haptic input device. The results of this study demonstrated that Fitts' Law was applicable to the evaluation of visio-hoptic workstations.…”

The present study aims to evaluate three commercial VR display devices on the market via a 3D Fitts' task. In addition, a Simulation Sickness Questionnaire (SSQ) was used to assess simulator sickness of participants. Ten participants performed repetitive pointing tasks over different conditions of varying display devices, movement directions and indices of difficulty. Based on the results, it seems that the 3D TV technology may not provide enough perceptual depth to enhance movement performance in a 3D VE. The projection display obtained the best performance and preference among the three display devices. The HMD gave the worst result in both the experimental task and the SSQ assessment due to the accompanied discomfort and fatigue.
