“…Distance-based approaches include head-pointing [61,84,93,97], controller-pointing [8,13,84], and hand/finger pointing [20,22]. For a more natural interaction, researchers investigated contact-based approaches with controllers [84,94] or hands/fingers [18,21,30,84]. For OST AR, virtual keyboards are also a common input technique [15,21,53,54,63,76,92,96], but far less explored than in VR.…”

Fig. 1: The virtual keyboard layout is based on the traditional layout of physical keyboards. (A) Shows the tap keyboard in video see-through augmented reality (VST AR) and (B) the swipe keyboard in virtual reality (VR) with a black tail following the user's controller. For the VR condition, we created an accurate digital twin of the real physical room. In the VST AR condition, the real world was captured by the video see-through capabilities of the XR device. To enable precise interaction, the user holds the controller upside down in a pen-like posture and presses/swipes the virtual keyboard keys with the bottom tip of the controller. Three word suggestions are displayed in the upper left. The arrow keys to move the cursor and the backspace key are located in the upper right. The cursor can also be positioned directly in the input field. The shift keys and the space bar are hidden on the swipe keyboard because they are not required for text entry. Rectangular 3D keys provide visual feedback, and when pressed, the controllers vibrate.

“…Capitalization and punctuation are often not considered [1,21,76,84], because researchers compared pure text input, rather than focusing on real-world usability. Dube and Arif [18] investigated different key dimensions and shapes on a virtual keyboard. The results showed a significantly lower error rate with 3D keys than with 2D keys.…”

Typing is still the primary input modality for computing systems. Most typical Virtual Reality (VR) setups replace users' capable hands and fingers with cumbersome hand-held controllers (HC). This study examines the hypothesis that finger interaction and realistic representation of users' hands increases typing performance, sense of Presence, and the usability of a typing system for a text transcription task in VR. We developed a hand and finger tracking and visualization system (VH) aimed to help users interact with on-screen keyboards in VR, and compared participants typing performance using HC. We found that the VH paradigm in VR significantly increased typing performance for inexperienced typists and that HC users were more prone to commit errors. Further research may delve deeper into the utility of VH input paradigm for people unable to grasp HCs and for other symbolic communications such as sign language.

“…For example, since the user do not see their own hands and the keyboard, those may be rendered to the user in new locations, for example closer to the document or the gaze direction of the user. Dube et al [26] explored the effect of rendering virtual keyboards' keys shapes and choose 3-dimensional square keys. Grubert et al [39] visualized the keys of a physical keyboard in VR and the fingertips of the user.…”

Virtual and Augmented Reality (VR and AR) have the potential to change information work. The ability to modify the workers senses can transform everyday environments into a productive office, using portable head-mounted displays (HMDs) combined with conventional interaction devices, such as keyboards and tablets. While a stream of better, cheaper and lighter HMDs have been introduced for consumers in recent years, there are still many challenges to be addressed to allow this vision to become reality. This chapter summarizes the state of the art in the field of extended reality for knowledge work in everyday environments and proposes steps to address the open challenges.
