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.

Growing Population

With a growing population of elderly people, more Web pages designed for the elderly appear. The design of Web pages not only is required to meet the physical characteristics of the elderly, but also needs to meet the characteristics of elderly visual behaviors. This study aims to investigate the strategy of elderly people in visual search and browse on Web pages using eye-tracking. The experimental results showed that, in visual search, the elderly people were under a higher mental load, and more likely to pay attention to the peripheral area; whereas in visual browse, their mental load is lower, and more likely to pay attention to central area. The results indicate that, the Web pages designed for the elderly should try to put the title with the hyperlink feature on the peripheral area, and put the main information content on the central area. Furthermore, it should take measures to reduce the mental stress of the elderly in visual search on Web pages.

Textual Cues

This study investigates how online dating profiles, consisting of both pictures and texts, are visually processed, and how both components affect impression formation. The attractiveness of the profile picture was varied systematically, and texts either included language errors or not. By collecting eye tracking and perception data, we investigated whether picture attractiveness determines attention to the profile text and if the text plays a secondary role. Eye tracking results revealed that pictures are more likely to attract initial attention and that more attractive pictures receive more attention. Texts received attention regardless of the picture’s attractiveness. Moreover, perception data showed that both the pictorial and textual cues affect impression formation, but that they affect different dimensions of perceived attraction differently. Based on our results, a new multimodal information processing model is proposed, which suggests that pictures and texts are processed independently and lead to separate assessments of cue attractiveness before impression formation.
