“…This is despite the difficulty this type of display can impose on the user for controlling other input devices like the keyboard and mouse which occurs mainly because the user cannot see the surrounding real environment when wearing the headset [12].…”

Virtual Reality (VR) has been proven to be capable of enabling its users to experience immersive virtual environments and interact with the computer. Most VR applications utilize stereo visual perception, however, stereo visual perception alone is not enough to fully immerse users in VR environments. Haptic feedback technology when applied to VR applications can offer improved immersion and interactivity and can extend the range of sensations experienced by the user. For example, tactile feedback can enable the user to feel an object they touch with their virtual hand or body. To provide tactile feedback in VR applications most researchers construct cumbersome mechanical actuators and linkages for applying feedback forces or vibrations to the user's real hand or body. Having to wear cumbersome feedback hardware can have the negative effect of making the user more aware of their physical body which can reduce the sense of being immersed in the VR world. To overcome this drawback we propose an alternative feedback system which is comprised of a hand gesture interface, a stereo visual head-set and an electro-tactile feedback system. Our electro-tactile feedback system is compact, simple, inexpensive and capable of delivering a variety of feedback sensations to the user. Experimental results are provided which demonstrate how the electro-tactile feedback system can enhance both the sense of immersion and interactivity for VR users.

“…"CAVE" is a multiple-face prism with images on each surface used in virtual reality (VR) environments. It has been rated as being adequate and ample as the "immersive" simulation of VR comparing to the insufficient head-mounted displays (HMDs) in that domain [15,16,17,18]. Nevertheless, current HMDs are able to rival with many CAVEs [19].…”

A ngular velocity perception plays an important role for a better sense of presence in driving simulators. This paper deals with the angular velocity perception threshold and sense of presence. A three degrees of freedom (DOF: roll, pitch, and heave) driving simulator, a motion tracking sensor, a driving simulation software, and self-prepared questionnaires were used. Due to the subjective assessments, there were no significant differences between static and dynamic platform types. Eight different cases were investigated with respect to visual and inertial factors (field of view (FOV) and motion platform). Subjective evaluations showed that there were no significant differences between static and dynamic conditions. Lower FOV, static platform, stereo vision condition has provided the best condition (best realism depending on objective-subjective measure relationship).

“…Moreover, Otmar et al presented 3D interactions with a situated see-through display [4]. However, one of the biggest hurdles in the current approach is that the display device cannot visualize the users' motions on the non-see-through HMD since an entire environment beyond the device is invisible during the operation [5]. Although, various research has been done or in progress to overcome the limitation, it is still an inevitable matter to have the method to control the user interface on the non-see-through head-mounted displays.…”

Abstract. This paper presents a platform, named Cybertouch, for 3D Virtual Reality Head-Mounted Display (VR HMD) providing both touch and cursor interface using wearable IMU devices to enable real-time selection of operational commands together with recognition of user motions and gestures. One of the constraints of the conventional 3D HMD widely used in VR games or training systems is blocking of user's visual perception while wearing an HMD. Because the environment and input devices are invisible during the operation, there may be a limitation in an application caused by restriction of user input commands. Proposed Cybertouch provides a User Interface which is a kind of combined functions of traditional mice and touch panel devices, specialized in games or immersive virtual training applications using 3D HMD.
