“…A variety of text entry methods for use when wearing VR HMD (both mobile and static) have been proposed. Outside of speech, none have been shown as approaching the performance of the standard PC keyboard [7]. There are many contexts in which speech may not be appropriate, we thus investigated how access to peripherals such as keyboards could be supported in VR.…”

“…Input actions occur in reality and in VR the user loses the inherent visual feedback for these actions. Many text entry methods for VR have been discussed [7], with voice input offering reasonable performance, however adoption of novel modalities will be slow and the use of keyboards is likely to continue, even if only transitionally. The keyboard is a ubiquitous input device and widely used by gamers (currently the key demographic for consumer VR HMDs); it is familiar, its layout is consistent, it has guidance for blind typing, and users are proficient in its usage.…”

We identify usability challenges facing consumers adopting Virtual Reality (VR) head-mounted displays (HMDs) in a survey of 108 VR HMD users. Users reported significant issues in interacting with, and being aware of their real-world context when using a HMD. Building upon existing work on blending real and virtual environments, we performed three design studies to address these usability concerns. In a typing study, we show that augmenting VR with a view of reality significantly corrected the performance impairment of typing in VR. We then investigated how much reality should be incorporated and when, so as to preserve users' sense of presence in VR. For interaction with objects and peripherals, we found that selectively presenting reality as users engaged with it was optimal in terms of performance and users' sense of presence. Finally, we investigated how this selective, engagement-dependent approach could be applied in social environments, to support the user's awareness of the proximity and presence of others.

“…The standard mobile phone touchscreen keyboard might be a suitable text entry method given that it is portable and provide a relatively high text entry rate with acceptably low error rates [7,26]. HoVR-type proposes using the hover function of some smartphones as a typing interface in VR [14] but no text entry rate is reported.…”

We study the performance and user experience of two popular mainstream text entry devices, desktop keyboards and touchscreen keyboards, for use in Virtual Reality (VR) applications. We discuss the limitations arising from limited visual feedback, and examine the efficiency of different strategies of use. We analyze a total of 24 hours of typing data in VR from 24 participants and find that novice users are able to retain about 60% of their typing speed on a desktop keyboard and about 40-45% of their typing speed on a touchscreen keyboard. We also find no significant learning effects, indicating that users can transfer their typing skills fast into VR. Besides investigating baseline performances, we study the position in which keyboards and hands are rendered in space. We find that this does not adversely affect performance for desktop keyboard typing and results in a performance trade-off for touchscreen keyboard typing.

AbstractAlphanumeric text entry is a challenge for Virtual Reality (VR) applications. VR enables new capabilities, impossible in the real world, such as an unobstructed view of the keyboard, without occlusion by the user's physical hands. Several hand representations have been proposed for typing in VR on standard physical keyboards. However, to date, these hand representations have not been compared regarding their performance and effects on presence for VR text entry. Our work addresses this gap by comparing existing hand representations with minimalistic fingertip visualization. We study the effects of four hand representations (no hand representation, inverse kinematic model, fingertip visualization using spheres and video inlay) on typing in VR using a standard physical keyboard with 24 participants. We found that the fingertip visualization and video inlay both resulted in statistically significant lower text entry error rates compared to no hand or inverse kinematic model representations. We found no statistical differences in text entry speed.
