“…One of the participants stated that it appeared that the double tap was better recognized because it was performed faster than the tap. The position error was not higher than those found in other studies [13,15].…”

“…Touchpads are highly mobile because they are attached to HMDs, but as with mid-air hand interaction, users must lift their hands to perform manipulations, and prolonged operation can increase user fatigue. Moreover, even though touch interaction is a familiar mode for users, it is difficult to use a touchpad because the touchscreen is on the side of the HMD [13]. Attaching the touchscreen to the front of the HMD allows direct manipulation of virtual objects through touch interaction and offers good mobility because the input device is attached to the HMD.…”

This study proposes FingerTouch, a method of touch interaction using a head-mounted display for mobile augmented reality. FingerTouch allows users to manipulate virtual content with one-finger touch interaction regardless of the material or tilt of the plane the finger is touching. In addition, users can interact freely with virtual contents using FingerTouch. As the prototype developed in this study uses only one inertial measurement unit sensor attached to a fingernail, it features high mobility and allows users to feel natural tactile feedback, which is important for performing everyday tasks. The user evaluation of FingerTouch indicated that it provides high accuracy, with an average cursor navigation error of 2.15 mm and an average finger gesture recognition accuracy of 95% across 22 participants, two surface orientations, and three surface materials. INDEX TERMS Augmented reality, finger gesture, inertial sensor, nail-mounted sensor, touch interaction.

“…Yu et al [21] also studied head-based text entry for VR and combined the concept with gesture-word recognition whereby experienced users perform up to 25 WPM. The VR system FaceTouch [5] leverages a touch-sensitive front cover of the HMD and the sense of proprioception to enable text input with up to ten WPM on a virtual keyboard.…”

Entering text is one of the most common tasks when interacting with computing systems. Virtual Reality (VR) presents a challenge as neither the user's hands nor the physical input devices are directly visible. Hence, conventional desktop peripherals are very slow, imprecise, and cumbersome. We developed a apparatus that tracks the user's hands, and a physical keyboard, and visualize them in VR. In a text input study with 32 participants, we investigated the achievable text entry speed and the effect of hand representations and transparency on typing performance, workload, and presence. With our apparatus, experienced typists benefited from seeing their hands, and reach almost outside-VR performance. Inexperienced typists profited from semi-transparent hands, which enabled them to type just 5.6 WPM slower than with a regular desktop setup. We conclude that optimizing the visualization of hands in VR is important, especially for inexperienced typists, to enable a high typing performance.

“…This raises questions about how to support this using the limited input techniques available with current mobile VR devices and the limited space available in a typical airline seat. Previous work has looked at different mobile input techniques such as touching the front of a head mounted display [22], but more research is needed to understand how to incorporate additional modalities and achieve better control when manipulating virtual objects.…”

“…If the only buttons available are incorporated into the headset, this could be a difficult situation for a spectator. An unwanted touch to a headset can be uncomfortable for a VR user [22], so external methods of interruption are needed if VR is going to leave the living room.…”
