Biswas, Pradipta, Langdon, Pat, Jung, Christoph, Hamisu, Pascal, Duarte, Carlos and Almeida, Lus (2012): Developing intelligent user interfaces for e-accessibility and e-inclusion. In: Proceedings of the 2012 International Conference on Intelligent User Interfaces 2012. pp. 405-408.

This workshop aims to gap the bridge between mainstream research on intelligent systems and accessibility researchers by presenting papers and demonstrations on developing adaptable multimodal systems for elderly and disabled users. The workshop is organized in the context of EU GUIDE project and focus on Web and Digital TV applications. However the research and applications are relevant for different platforms like computers, tablet and ubiquitous devices. The workshop consists of a keynote speech on standardization of developing intelligent and accessible system followed by five paper and demonstration presentations. A set of papers from this workshop will later appear at the International Journal of Digital Television.

Coelho, Jos, Duarte, Carlos, Biswas, Pradipta and Langdon, Patrick (2011): Developing accessible TV applications. In: Thirteenth Annual ACM SIGACCESS Conference on Assistive Technologies 2011. pp. 131-138.

The development of TV applications nowadays excludes users with certain impairments from interacting with and accessing the same type of contents as other users do. Developers are also not interested in developing new or different versions of applications targeting different user characteristics. In this paper we describe a novel adaptive accessibility approach on how to develop accessible TV applications, without requiring too much additional effort from the developers. Integrating multimodal interaction, adaptation techniques and the use of simulators in the design process, we show how to adapt User Interfaces to the individual needs and limitations of elderly users. For this, we rely on the identification of the most relevant impairment configurations among users in practical user-trials, and we draw a relation with user specific characteristics. We provide guidelines for more accessible and centered TV application development.

Biswas, Pradipta and Langdon, Pat (2011): The effect of hand strength on pointing performance of users for different input devices. In: Thirteenth Annual ACM SIGACCESS Conference on Assistive Technologies 2011. pp. 289-290.

We have investigated how hand strength affects pointing performance of people with and without mobility impairment in graphical user interfaces for four different input modalities. We have found that grip strength and active range of motion of wrist are most indicative of the pointing performance. We have used the study to develop a set of linear equations to predict pointing time for different devices.

Biswas, Pradipta and Robinson, Peter (2010): Evaluating the design of inclusive interfaces by simulation. In: Proceedings of the 2010 International Conference on Intelligent User Interfaces 2010. pp. 277-280.

We have developed a simulator to help with the design and evaluation of assistive interfaces. The simulator can predict possible interaction patterns when undertaking a task using a variety of input devices, and estimate the time to complete the task in the presence of different dis-abilities. In this paper, we have presented a study to evaluate the simulator by considering a representative application being used by able-bodied, visually impaired and mobility impaired people. The simulator predicted task completion times for all three groups with statistically significant accuracy. The simulator also predicted the effects of different interface designs on task completion time accurately.

Biswas, Pradipta and Robinson, Peter (2009): Modelling perception using image processing algorithms. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 494-503.

User modeling is widely used in HCI but there are very few systematic HCI modelling tools for people with disabilities. We are developing user models to help with the design and evaluation of interfaces for people with a wide range of abilities. We present a perception model that can work for some kinds of visually-impaired users as well as for able-bodied people. The model takes a list of mouse events, a sequence of bitmap images of an interface and locations of different objects in the interface as input, and produces a sequence of eye-movements as output. Our model can predict the visual search time for two different visual search tasks with significant accuracy for both able-bodied and visually-impaired people.

Biswas, Pradipta (2008): Simulating HCI for all. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2649-2652.

Computers offer valuable assistance to people with physical disabilities. However designing human-computer interfaces for these users is complicated. The range of abilities is more diverse than for able-bodied users, which makes analytical modelling harder. Practical user trials are also difficult and time consuming. I am developing a simulator to help with the evaluation of assistive interfaces. It can predict the likely interaction patterns when undertaking a task using a variety of input devices, and estimate the time to complete the task in the presence of different disabilities and for different levels of skills.
