Augmented Reality Marauder’s Map of Georgia Tech

“The Marauder’s Map” is a magical map in J. K. Rowling’s fantasy series, “Harry Potter and the Prisoner of Azkaban”. When being used by wizards who “solemnly swear that I am up to no good”, it shows all moving objects within the boundary of the “Hogwarts School of Witchcraft and Wizardry”. In this paper, we […]

Week 13 Summaries

OmniTouch: Wearable Multitouch Interaction Everywhere This paper by Harrison et al is a more recent, robust (and real) implementation of the Sixth Sense tech by Pranav Mistry et al. The group has implemented the system using depth sensing technology similar to Kinect. They have also mentioned the work done by Sixth Sense and Interactive Dirt, […]

Week 12 Summaries

Exploring 3D Navigation : Combining Speed-coupled Flying with Orbiting The introduction of this paper hits home the importance of the research the paper is doing. As they state in the paper, virtual environments generally comprise of worlds which are larger than that can be viewed from a single vantage point. In order to experience the […]

Week 11 Summary

Different input techniques were discussed in this paper using the medium of push buttons. Two different implementations were tested using a TriggerGun and FingerSleeve. The trigger gun is is looks very much like a ill designed (ok fine, its a prototype) air craft controller joystick, made of clay which has two buttons, one in front […]

Week 10 summary

Physiological Measures of Presence in Stressful Virtual Environments Presence is defined as “the feeling of being there”. The best way to calculate the level of presence managed by a VE experience is by comparing the responses of people to a similar “there” situation, I mean a real situation. As noted by the paper, the feeling […]

Week 9 Summaries

DART: A Toolkit for Rapid Design Exploration of Augmented Reality Experiences   The thing that clicked with me the most is the aim to shift people’s notion of AR as a technology to AR as a medium. You don’t consider take photos or video from a point-and-shoot as technology, buy maybe shooting from a DSLR […]

Assignment 1 – Croquet Reloaded

Idea A simple game of Croquet, modified for continuous interaction. The aim is to pass the ball through the hoop at the other end. You have 3 colored balls which get triggered by 3 frame markers. By moving the frame marker left/right you can control the direction of the ball. Will you fail or succeed? Implementation 1. Initital […]

Week 8 Summary

Pre-Patterns for Designing Embodied Interactions in Handheld Augmented Reality Games   Any problem with a new alternative technology is, that its development is lead by developers. The initial work and examples on it focus on the technical boundaries they are able to push. However, a problem that starts becoming evident as the technology matures and […]

Week 7 Summary : AR supported collaboration

The two papers we read this week had a common theme that they enable collaboration, allowing multiple people to participate on a singular “workbench” though enable a personal view for each viewer. Each paper uses a different technique to enable head-tracking of each user. SCAPE: Stereoscopic Collaboration In Augmented and Projective Environments. Multiple users can […]

Week 6 Summary: Stereo vs. Eye-coupled perspective

Before reading this paper, I googled Fish Tank VR and found the Colin Ware and Kevin Arthur paper title “Fish tank Virtual reality” and their abstract concluded that head coupling is probably more important than stereo in 3D visualization and that head coupling and stereo combined provide an important enhancement to monitor based computer graphics. When I […]

Week 5 Sumary : Kinect Fusion & More

KinectFusion is a great example of SLAM (Simultaneous localization and Mapping Systems). In most AR systems it was assumed prior knowledge of the user’s environment. Maybe a map of the city. Or use co-ordinates to merge a Google earth 3D model with the real world. Maybe a point of interest , Eiffel Tower, or the printer […]

Week 3 Summary: One context – Multiple applications

The “app” paradigm that took the mobile industry by storm, has brought on the concept of micro-applications that fulfill one purpose. This is great in terms of maintaining focus, but there is very little interoperability between apps. I need to look for a restaurant, use a different app. I need to take a bus till […]

Vipul – Week 2 Summary : Heights. Scan. Action.

Heights. Virtual Environments for Treating the Fear of Heights Hodges, L., Barbara Rothbaum, Rob Kooper, Dan Opdyke, Tom Meyer, Max North, Johannes de Graaff, & James Williford This was an experiment to use VR to treat Acrophobia – Fear of Heights using the method of Graded Exposure by taking the patient ‘out into the real […]
