Requirement analysis and realization of accessible multi-modal Web browsing

[go to bachelor theses]

Open Bachelor Thesis - Contact a supervisor for more details!

Access to digital information and communication is part of our daily life. However, most applications and especially Web sites are not adapted for the use by people with motor impairment who may be limited in their control of mouse and keyboard. Thus, we have developed GazeTheWeb [3], an award winning Web browser that can be controlled exclusively with eye gaze. As a next step, we want to move beyond “GazeTheWeb being a useful tool” to “make it usable for people” with various special needs. For the purpose, design modifications, and integration of further modalities, like touch control, voice input, tactile buttons, or head tracking need to be studied.

In this thesis, you (i) perform a requirement analysis with a person with motor impairment. Then, you (ii) decide which modalities and design changes shall be integrated into the system to enhance the accessibility of interaction for that person. You (iii) implement the chosen modalities and (iv) perform a case study with the person. The adaptation shall be geared towards further extensibility in the future.

We have contact with a person with motor impairment from Cologne who wants to participate in the requirement analysis and the case study. Furthermore, you will be technically supported by our student assistant who maintains GazeTheWeb.

This work is planned as an important step to enhance the general usability of GazeTheWeb and make this kind of assistance more widely available to handicapped people world wide.

Prerequisite: Students from computer science / information management / computer visualisitics are eligible for the thesis. However, based on your study background we can decide the main focus of work on programming / user interview / design. German language knowledge would be helpful to effectively communicate with the person with motor impairment.
