Efficient Rasterization for Edge-based 3D Object Tracking on Mobile Devices (2012)
Presentation / Conference Contribution
Kissling, E., Mitchell, K., Oskam, T., & Gross, M. (2012). Efficient Rasterization for Edge-based 3D Object Tracking on Mobile Devices. In SIGGRAPH Asia 2012 Technical Briefs (12:1-12:4). https://doi.org/10.1145/2407746.2407758

Augmented reality applications on hand-held devices suffer from the limited available processing power. While methods to detect the location of artificially textured markers within the scene are commonly used, geometric properties of three-dimensiona...

Runtime Implementation of Modular Radiance Transfer. (2011)
Presentation / Conference Contribution
Loos, B., Antani, L., Mitchell, K., Nowrouzezahrai, D., Jarosz, W., & Sloan, P. (2011). Runtime Implementation of Modular Radiance Transfer. In ACM SIGGRAPH 2011 Talks (59:1-59:1). https://doi.org/10.1145/2037826.2037905

Real-time rendering of indirect lighting significantly enhances the sense of realism in video games. Unfortunately, previously including such effects often required time consuming scene dependent precomputation and heavy runtime computations unsuitab...

Surround Haptics: Sending Shivers Down Your Spine (2011)
Presentation / Conference Contribution
Israr, A., Poupyrev, I., Ioffreda, C., Cox, J., Gouveia, N., Bowles, H., …Williams, T. (2011). Surround Haptics: Sending Shivers Down Your Spine. In ACM SIGGRAPH 2011 Emerging Technologies (14:1-14:1). https://doi.org/10.1145/2048259.2048273

Surround Haptics is a new tactile technology that uses a low-resolution grid of inexpensive vibrating actuators to generate high-resolution, continuous, moving tactile strokes on human skin [1]. The user would not feel the discrete tactile pulses and... Read More about Surround Haptics: Sending Shivers Down Your Spine.

Light factorization for mixed-frequency shadows in augmented reality (2011)
Presentation / Conference Contribution
Nowrouzezahrai, D., Geiger, S., Mitchell, K., Sumner, R., Jarosz, W., & Gross, M. (2011, October). Light factorization for mixed-frequency shadows in augmented reality. Presented at IEEE International Symposium on Mixed and Augmented Reality 2011

Integrating animated virtual objects with their surroundings for high-quality augmented reality requires both geometric and radio-metric consistency. We focus on the latter of these problems and present an approach that captures and factorizes extern... Read More about Light factorization for mixed-frequency shadows in augmented reality.

Split Second Motion Blur (2010)
Presentation / Conference Contribution
Ritchie, M., Modern, G., & Mitchell, K. (2010). Split Second Motion Blur. In ACM SIGGRAPH 2010 Talks (17:1-17:1). https://doi.org/10.1145/1837026.1837048

Motion blur is key to delivering a sense of speed in interactive video game rendering. Further, simulating accurate camera optical exposure properties and reduction of temporal aliasing brings us closer to high quality real-time rendering productions... Read More about Split Second Motion Blur.

Using active constructs in user-interfaces to object-oriented databases. (1997)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1997). Using active constructs in user-interfaces to object-oriented databases. In Proceedings [of the First] International database engineering and applications symposium, (3-12)

This paper examines the use of active constructs in the definition of user-interfaces to object-oriented databases. A development environment for user-interfaces to databases is presented which features the interactive use of active features of an ob...

The perspective tunnel: An inside view on smoothly integrating detail and context. (1997)
Presentation / Conference Contribution
Mitchell, K., & Kennedy, J. (1997, April). The perspective tunnel: An inside view on smoothly integrating detail and context. Presented at Proc. of Eurographics Workshop on Visualisation in Scientific Computing

The perspective tunnel, a general kind of information visualisation artefact, embodies a visual form which exploits natural human visual perception. Perspective tunnels map information on to the floor, ceiling and walls of a tunnel, so that both ever...

DRIVE: An environment for the organised construction of user interfaces to data. (1996)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1996, July). DRIVE: An environment for the organised construction of user interfaces to data. Presented at 3rd International Workshop on User Interfaces to Databases - IDS3, 1996

This paper describes a runtime user-interface development environment (UIDE) for the novel capability of interactively using and specifying user-interfaces to object-oriented databases (IDSs). A framework provides the foundation for IDSs constructed... Read More about DRIVE: An environment for the organised construction of user interfaces to data..

Describing and characterising visualisations. (1996)
Presentation / Conference Contribution
Kennedy, J. B., Mitchell, K. J., & Barclay, P. J. (1996). Describing and characterising visualisations. In 3rd FADIVA Workshop

A generic framework for describing and specifying interfaces to databases has been proposed [1]. Currently this framework is being used as a model for the development of an environment for the construction of user interfaces to object oriented datab...

A framework for user-interfaces to databases (1996)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1996, May). A framework for user-interfaces to databases. Presented at International Workshop on Advanced Visual Interfaces, AVI\'96

A framework for user-interfaces to databases (IDSs) is proposed which draws from existing research on human computer interaction (HCI) and database systems. The framework is described in terms of a classification of the characteristic components of a... Read More about A framework for user-interfaces to databases.

Using a conceptual data language to describe a database and its interface (1995)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1995, July). Using a conceptual data language to describe a database and its interface. Presented at 13th British National Conference on Database - BNCOD13, 1995, University of Manchester

We propose a conceptual approach to defining interfaces to databases which uses the features of a fully object oriented data language to specify interface objects combined with database objects. This achieves a uniform, natural way of describing data... Read More about Using a conceptual data language to describe a database and its interface.
