Some Human Factors Considerations for Designing Mixed Reality Interfaces.

摘要

Mixed Reality (MR) refers to the general case of combining images along a continuum which ranges from purely real (unmodelled) data, such as raw video images, to completely virtual images, based on modelled environments. Depending on where a particular display mode lies on the reality-virtuality continuum, MR encompasses the case of Augmented Reality (AR), as well as the case of Augmented Virtuality (AV). In designing human-machine interfaces for mixed reality applications, a number of considerations are discussed which may potentially impact the effectiveness of the design. In addition to the real- virtual image content (which is closely related to how much knowledge is available about the images being displayed), these include the (visual) perceptual impact of the display technologies used for combining real and virtual images, which manifest themselves in particular when virtual objects must be aligned with real ones, for applications such as AR mediated teleoperation. Other considerations include where the user's particular viewpoint lies along a continuum ranging from ego- to exo-centricity, as well as control-display congruence issues constrained by the other MR factors.
