Data on various eye movement measures for a variety of reading, problem solving and search behaviour

The objective of the I-EYE project was to develop new, natural forms of interaction for multilingual applications, and to evaluate their usability.

UNO performed a wealth of experimentation that generated data that could be used to develop the thresholds for eye movement triggering of functions. This experimentation examined various eye movement measures for behaviour that related to both the iDict and iTutor applications. The data generated, provided norms and differential values for eye movement behaviour for reading, problem solving and search behaviour. These data give an indication of baseline values, and efficient and problematic behaviour that can be used to ascertain when additional information is required.

The data relating to iDict application (another application developed in the framework of the I-EYE project) provided eye movement measures that are indicative of a comprehension breakdown in reading for both readers who are reading text in a native or secondary language and also indicated differences between scan and vigilant reading. The data relating to iTutor provides information in terms of efficient and problematic problem solving as well as differences between various search strategies. The data generated also identified differences in eye movement measures between processing information across different information formats.

All the data is of scientific interest and can also be used internally to aid the development of algorithms that use eye movements to trigger the software functioning.
