Augmented Reality Support
Services supporting AR within an area, must provide accurate positioning
information to facilitate the display/capture of locative media in appropriate
places. A variety of HMIs cab be used including wearable consumer head-up
displays (HUDs), handheld small screens and linked public displays, all of which
react in response to user motion and context. Markets include:
•
AR games and especially collaborative gaming;
•
Collaborative and distributed sports (e.g., geographically separated
racing);
•
Educational overlays for out-of-school activities;
•
Multimedia narratives for tourism;
•
Enhanced experiences for museums and historic monuments both
indoors and outdoors (e.g., showing original historical context and in-
filling of missing architectural artifacts);
•
Virtual tourism;
•
Cinematic activities, blending real object movement with virtual object
movement.
Benefits are enhanced social, educational, recreational, and cultural
experiences that may be highly engaging, popular, and thus commercially
attractive. There may be cultural benefits leading to opportunities to engage with
people in other regions by “making geography, history,” including travel
reduction leading to cost savings and reduction in environmental damage.
Weaknesses include more public backlash about artificial experiences, and
there may be possible safety hazards (e.g., walking into things) and dangers of
new social experiences and norms, leading to unacceptable behavior.
As well, very high accuracy location would be needed in certain locations
(<1m) and there is a need for accurate orientation. Very low latency is required;
for motion picture capture accuracy <10cm is required.
This is a very demanding set of applications. Wireless sensing technology is
not always adequate so reliance on video capture of motion is needed, as
explained in Section 7.4.5. Integration is needed with 4D GIS (i.e., 3D space plus
time—See Section 8.8) and integration with many types of media, including
haptic or touch technology.

Scenarios for the Future
The end of Chapter 9 discusses a Whereness vision in terms of user equipment
and services. It continues with the themes in this chapter, which are futuristic and
will mostly not be common for at least a decade. The next three chapters are more
