Knowledge is commonly socially constructed, through collaborative efforts towards shared objectives or by dialogues and challenges brought about by different persons' perspectives.

Metatla, Oussama, Bryan-Kinns, Nick, Stockman, Tony and Martin, Fiore (2012): Supporting cross-modal collaboration in the workplace. In: Proceedings of the HCI12 Conference on People and Computers XXVI 2012. pp. 109-118.

We address the challenge of supporting collaborators who access a shared interactive space through different sets of modalities. This was achieved by designing a cross-modal tool combining a visual diagram editor with auditory and haptic views to allow simultaneous visual and non-visual interaction. The tool was deployed in various workplaces where visually-impaired and sighted coworkers access and edit diagrams as part of their daily jobs. We use our observations and analyses of the recorded interactions to outline preliminary design recommendations for supporting cross-modal collaboration.

Metatla, Oussama, Bryan-Kinns, Nick and Stockman, Tony (2008): Constructing relational diagrams in audio: the multiple perspective hierarchical approach. In: Tenth Annual ACM SIGACCESS Conference on Assistive Technologies 2008. pp. 97-104.

Although research on non-visual access to visually represented information is steadily growing, very little work has investigated how such forms of representation could be constructed through non-visual means. We discuss in this paper our approach for providing audio access to relational diagrams using multiple perspective hierarchies, and describe the design of two interaction strategies for constructing and manipulating such diagrams through this approach. A comparative study that we conducted with sighted users showed that a non-guided strategy allowed for significantly faster interaction times, and that both strategies supported similar levels of diagram comprehension. Overall, the reported study revealed that using multiple perspective hierarchies to structure the information encoded in a relational diagram enabled users construct and manipulate such information through an audio-only interface, and that combining aspects from the guided and the non-guided strategies could support greater usability.

Metatla, Oussama, Bryan-Kinns, Nick and Stockman, Tony (2008): Comparing Interaction Strategies for Constructing Diagrams in an Audio-only Interface. In: Proceedings of the HCI08 Conference on People and Computers XXII 2008. pp. 65-69.

Although research on non-visual access to visualisations is steadily growing, very little work has investigated strategies for constructing such forms of representation through non-visual means. This paper describes the design of two interaction strategies for constructing and manipulating relational diagrams in audio. We report on a study that compared the two strategies, and discuss their advantages and disadvantages in terms of how efficiently they support the activity of constructing diagrams in an audio-only interface.
