“…There remains the question of managing this augmentation of virtuality i.e. managing traversals or transitions within the virtuality continuum as discussed by Davis et al [6]. Most research has examined mixed reality boundaries [2] where physical boundaries mark crossovers between mixed and virtual reality [8].…”

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 HMPD technology has also been explored in multiuser collaborative environments. For instance, Rolland et al 20 and Davis et al 25 have demonstrated a deployable room display environment for medical training. By exploring several unique properties inherent in HMPD technology, Hua et al have developed a multiscale collaborative infrastructure, referred to as SCAPE, to support versatile modes of user interaction and collaborative operation in augmented virtual environments.…”

In optical see-through head-mounted displays, it has been a common challenge that the displayed image lacks brightness and contrast compared with the direct view of a real-world scene. Consequently, such displays are usually used in dimmed lighting conditions, which limits the feasibility of applying such information displays outdoors or in scenarios where well-lit environments, such as in operation rooms, are required. The lack of image brightness is aggravated in the design of a see-through head-mounted projection display (HMPD). For instance, the overall flux transfer efficiency of existing HMPD designs is less than 10%. The design of a polarized head-mounted projection display (p-HMPD) is presented. The images of a p-HMPD system can potentially be three times brighter than those in existing HMPD designs. It is further demonstrated that the p-HMPD design is able to dramatically improve image brightness, contrast, and color vividness with experimental results. Finally, the design of a compact optical system and helmet prototype is described.

“…The rVA experiments were conducted within an augmented reality visualization center (ARC) shown in Figure 2. The ARC is a prototype multi-modal augmented reality system with 3D visual, 3D audio and haptic capabilities configured as a quasi-circle of 4.57 m (15 ft) diameter (Davis, Rolland, Hamza-Lup, & Ha, 2003;Rolland, Stanney, et al 2004). The display consisted of a curved wall of retroreflective material, and a Linux-based PC.…”

Head-mounted display design is an iterative process. As such, a standardized usercentered assessment protocol of head-mounted performance during each phase of prototype development should be employed. In this paper, we first describe a methodology for assessing prototype head-mounted displays and virtual environments using visual performance metrics. We then present an application of the methodology using a prototype of a projection head-mounted display and the first module of our assessment: resolution visual acuity as a function of contrast. To evaluate the total system, we also used three different light levels and two different types of projection materials. Results from both studies indicate that the visual acuity metric resolution accurately identified reductions in user visual acuity caused by parameters of the projection display and those of the phase conjugate material. Results further support the need for benchmark metrics that allow comparison of prototype head-mounted performance through each stage of design.
