week 13 summaries

OmniTouch: Wearable Multitouch Interaction Everywhere The paper discusses a novel wearable interactive system introduced by Microsoft. The system tries to leverage the ubiquitous access to information, its manipulation and sharing especially through mobile and cloud devices. However, the most prevalent interfaces available have limited screen real estate and modes of interaction. Omnitouch is an interactive […]

week 12 summary [Hitesh]

Exploring 3D navigation: Navigating an interacting in a 3D world is a lot more challenging than rendering one. Also, the usability and effectiveness of a virtual environment largely depends upon the user’s ability to get around and interact with the information within it. The paper discusses previous research efforts to construct taxonomy of navigation techniques. […]

Project Progress report – Stage 2

As part of our proposed application to develop a Marauders Map AR application, we have made following progress: 1)      When the application loads, an overview of Marauder’s Map is displayed along with a CSS button which says – ‘Touch and Hold to take oath’. As the user holds the button, the oath appears on the […]

Variations in Physiological Responses of Participants During Different Stages of an Immersive VirtualEnvironment Experiment The paper talks about measuring presence in a virtual environment through the physiological responses of a user in the system. It defines Presence as use’s response to virtual stimuli when there is a successful substitution of real sensory data by computer […]

Project Progress – Marauders map [March 11, 2013 – stage 1]

As part of our proposed application to develop a Marauders Map AR application, we have made following progress: 1)      The marauders map being overlaid on an image tracker. The map shows different rooms which would be the play area for different challenges. 2)      A pair of footsteps being displayed on the map when the camera […]

week 9 summary – paper discussion for DART [Hitesh]

Creating a compelling AR application through a programmable interface requires extensive knowledge about 3D geometry, tacking, camera and displays. This makes it difficult for designers to iteratively develop and evaluate AR solutions through prototyping, which is a very popular and effective design application process for 2D and web applications. It limits the creative process of […]

Assignment 1 – Hitesh

Tetris in AR The assignment was an effort to try simulating the game of Tetris in an AR environment. The Image target was a game logo of Tetris. The main setup of the game consists of a horizontal bar surrounded by two vertical bars at the end. Two frame markers were used to introduce blocks/cubes […]

week 8 summaries – Hitesh

Pre-Patterns for Designing Embodied Interactions in Handheld Augmented Reality Games The paper talks about the research of design patterns and principles in reality based interfaces such as Handheld Augmented Reality (HAR) interfaces, which create embodied game play experiences. Being a fairly recent and evolving field, design patterns for HAR are referred to as “Pre-design” patterns […]

week 7 summaries – Hitesh

Multi-viewer Tabletop Autostereoscopic Display The paper mentions a novel and practical Auto stereoscopic tabletop displays which would provide stereo perception to multiple users without special glasses. The main challenge is to provide multiple stereo viewpoints to different users at the same time through the same interface. Existing auto stereo display technologies mostly fall under three […]

week 6 summary – Hitesh

Importance of Stereo and Eye-Coupled Perspective for Eye-Hand Coordination in Fish Tank VR The paper intends to investigate the importance of different kinds of depth cues in 3D perception depending upon the kind of task being performed. It also takes into account the probable advantages of head tracking for visual guided tasks. The two depth cues being referred […]

week 5 summary – Hitesh

Kinect Fusion Kinect Fusion is one of the latest technological advancements in AR. It uses depth data from Kinect sensor to track 3D pose and constructs a 3D representation of the object in the real time. It vouches to be a cost-effective and seamless augmentation of 3D physical data on the real world. As opposed […]

week 4 summary – Hitesh

The paper highlights some of the existing issues with location based tracking systems in a real world MR and wearable systems, that it requires the objects in the environment to be pre-mapped or marked thus not making the system extensible and robust. Computer vision tracking poses a lot of challenges and requires complex algorithms and […]

week 3 summary on Argon – Hitesh

The paper describes the background study, motivations and the technology directions towards development of the ARGON web browser. It defines the key goals towards creating an immersive and interactive AR web browsing for mobile devices. I think it involved a lot of research and effort to not just develop an AR browser that supports Augmented […]

Hitesh – week 2 summary

Designing Interactive Theme Park Rides The paper highlights the design, motivation and the relevant elements of virtual reality for an Interactive theme park game based on the concept of Pirates of the Caribbean.  The game is targeted for a group of 4 users taking into account the usual user group of such theme parks. The […]
