Non-command user interfacesCompared to the use of any other input channel, eye-gaze has a unique property: it implicitly carries information on the focus of the user's attention. So far, computers have not made use of this information. We are studying ways of making the computer adapt its operation based on where the user is looking. As an application demonstrating such behavior, we are developing an automatic reading aid. When the user reads foreign text on the screen, changes in gaze patterns can reveal comprehension problems, and the computer can then provide the translation automatically. Gaze-controlled user interfacesUsing the eyes to control the mouse pointer, for instance, is an idea that may sound great. If implemented as such, however, it is unlikely to work: the eyes are extremely fast, and eye movements are hard to control consciously. Our aim is to develop new techniques and interaction widgets that make eye control more appropriate for everyday use. In addition, we will use these techniques in applications specifically intended for disabled users, for whom eye-based communication may be the only available option. In particular, we will be developing and studying a system for typing text using solely the eyes.
Eye Typing Gaze paths in analyzing interfacesEver been annoyed by blinking and flashing ads when you have tried to make sense of a web page? The effectiveness of various visual elements is of great commercial interest, too, and eye-tracking can be used to study what attracts the attention of the user. Together with screen layout, these are important elements in the usability of user interfaces. Our third line of research concentrates on the use of eye trackers in analyzing interfaces. It combines both practical studies and the use of eye-tracking in developing models for gaze behavior in human-computer interaction. Gaze behavior and perceptionWhat makes one product look attractive and another not? Is your attention drawn to the aspects that the designers intended? The "Perception of Design" research project aims at developing a research method for studying the perception of design products and comparing how design professionals and consumers perceive design products. Another goal is to compare the perception of virtual models and real objects. A special challenge in the project is to let the users manipulate the products, instead of fixing them in a specific location. Eye-tracking tools and analysis software will be developed and used to record and analyze the gaze paths of users. This is a co-operation project with the University of Art and Design Helsinki. |
