Abstract Background: Apart from a straight-forward and intuitive operability an appealing design determines the success of a website equally well. For this reason, the selection of images and navigation bars plays a determining role. The eye tracking method proved to be appropriate in order to verify the usability of websites. Objectives: The aim of the study was to improve the usability of the website of an educational institute for trainees as target group. Methods/Approach: For this purpose, the use of an eye-tracking technology was combined with a survey. The eye-tracking study was implemented task-oriented. Test persons were asked to search for particular courses within this institute. Results: This approach in combination with a subsequent questionnaire resulted in tangible indications of search patterns of the test group. Furthermore, their perception and their appraisal of the usability as well as the web design was analysed. Even though most tasks were accomplished effectively and efficiently with a positive user feedback, a potential for improvement was detected, in particular with regard to the images and the location of the search field. Conclusions: The selected choice of methods enables researchers and web designers to derive recommendations for the orientation, structure, optimisation and comprehensibility of a website.

Tracking Technology

A challenge with current Computerized Provider Order Entry (CPOE) systems includes patient identification errors, i.e. when an incorrect patient’s record is referenced. These types of errors can lead to patient safety issues such as administrating medication to the incorrect patient. Eye tracking technology can provide insights into the visual search patterns of healthcare professionals and shed light on how patient identification errors occur. This study investigates whether there are differences in visual search metrics, response time, and accuracy when searching for a patient by two identifiers – name or date of birth – from a list of patients with similar names. The findings revealed there was no effect of search strategy on speed or accuracy; however, there was an effect on fixation duration and number of fixations within specific areas of interest. Across both search strategies, there were more fixations on names. This demonstrates the importance of a patient’s name regardless of search strategy and is an important consideration to take into account if multiple patients share the same name. This study shows that eye tracking technology can be used to investigate the visual search patterns employed during patient identification and provide insights as to how patient identification errors occur. It also demonstrates a need to develop alternative methods to prevent patient identification errors apart from relying on healthcare professionals to verify patient identity.

As an initial channel for users learning about a mobile game, the interactive experience of the navigation interface will directly affect the first impression of the users on the game and their subsequent behaviors and willingness to use. This study aims to investigate players’ visual attention mechanisms of various interactive levels of mobile games’ interfaces under free-browsing and task-oriented conditions. Eye-tracking glasses and a questionnaire were used to measure the interactive experience of mobile games. The results show that in the free-browsing condition, the fixation count, saccade count and average saccade amplitude can be used to reflect and predict the interactive experiences of mobile games’ navigation interface; while in the task-oriented condition, the fixation count, first fixation duration, dwell time ratio and saccade count can be used to reflect and predict the interactive experience of mobile games’ navigation interface. These findings suggest that apart from the different eye movement indicators, players’ motivations should also be considered during the process of the games’ navigation interface design.

Tracking Technology

Multimedia students’ dependence on information from the outside world can have an impact on their ability to identify and locate information from multiple resources in learning environments and thereby affect the construction of mental models. Field dependence-independence has been used to assess the ability to extract essential information from the environment. This study utilized eye-tracking technology to explore whether field-dependent and field-independent (FI) learners differed in their visual searching efficiency and multimedia learning performance. The FI learners outperformed field-dependent learners in posttest indices. In addition, FI learners were better able to identify visual cues and demonstrated efficient visual search patterns when learning using different information formats. The research findings echoed previous findings: The dependence on information in the context of learning can affect learners’ visual search efficiency and learning performance. The findings of this study suggest that adaptable learning environments that provide a rich variety of media may benefit learners with different levels of information-dependence. Applying eye-tracking technology enabled blueprints to be created pertaining to the learners’ information processing. However, additional research techniques, such as think-aloud exercises, would enable deeper understanding of how learners construct mental models of a knowledge base in a multimedia learning environment.

AbstractMaps that correctly represent the geographic size and shape of regions, taking into account scaling and generalization, have the disadvantage that small regions can easily be overlooked or not seen at all. Hence, for some map use tasks where small regions are of importance, alternative map types are needed. One option is the so-called equal area unit maps (EAUMs), where every enumeration unit has the same area size, possibly also the same basic shape such as squares or hexagons. The geometrical distortion of EAUMs, however, leads to a more difficult search for regions as well as a falsification of topological relationships and spatial patterns. To describe these distortions, a set of analytical measures is proposed. But it turns out that the expressiveness of these measures is rather limited. To better understand and to model the influence of distortions, two user studies were conducted. The study on the search in EAUMs (also with the aim of reconstruct the search strategies of the users) revealed how important it is to consider the local topology (e.g. corner or border positions of regions) during the generation process. With regard to pattern identification, it could be shown that EAUMs significantly increase the detection rate of local extreme values. On the other hand, global lateral gradients or geostatistical hot spots often get blurred or even lost. As a consequence, a task-oriented selection of map types and further developments are recommended.
