Our Research

The Human-Computer Interaction is an interdisciplinary field, studying the factors that affect the quality and effectiveness of the use of computing systems. We focus on methods of clear communication of information to the users through various modalities, as well as on novel input techniques for various "non-traditional" user groups, such as people in mobile situations, the elderly, the vision-impaired, or the people with motor impairments.

Our Current Work

Navigation system NaviTerier for vision-impaired people

The project consists of a design and implementation of a system for an in-door and outdoor navigation of vision-impaired people using mobile telephones. Our system requires no dedicated technology. It relies on mobile telephones with voice output which is in a common use among the vision-impaired. The system is based on detailed description of landmarks of the environment which is mediated via speech interface.

Input devices for people with motor impairments

The people with motor impairments have problems with using standard devices such as mouse or keyboard. We develop dedicated techniques of analysis of sound and bio-signals that we use to control the emulators of standard input devices. Examples of our applications include computer games controlled by voice and entering text via processing of the myoelectric signals.

Novel methods in software usability testing

Usability is a quality of a software product that is easy to learn, efficient to use, and that brings satisfaction to its users. The usability testing is an umbrella term for more or less formalized methods, based on observing user's work with the device being tested. Considerable amounts of data are acquired during the tests (observers. notes, audio, video, screen cast, results of eye tracking, etc.). Efficient handling of these data is a challenge that requires novel methods of annotation, visualization, etc.
