This paper presents a study which examined the selection of Web search results with a gaze-based input device. A standard list interface was compared to a grid and a tabular layout with regard to task performance and subjective ratings. Furthermore, the gazebased input device was compared to conventional mouse interaction. Test persons had to accomplish a series of search tasks by selecting search results. The study revealed that mouse users accomplished more tasks correctly than users of the gazebased input device. However, no differences were found between input devices regarding the number of search results taken into account to accomplish a task. Regarding task completion time and ease of search result selection only in the list interface gaze-based interaction was inferior to mouse interaction. Moreover, with a gaze-based input device search tasks were accomplished faster in tabular presentation than in a standard list interface, suggesting a tabular interface as best suited for gaze-based interaction.

The portability of an eye tracking system encourages us to develop a technique for estimating 3D point-of-regard. Unlike conventional methods, which estimate the position in the 2D image coordinates of the mounted camera, such a technique can represent richer gaze information of the human moving in the larger area. In this paper, we propose a method for estimating the 3D point-of-regard and a visualization technique of gaze trajectories under natural head movements for the head-mounted device. We employ visual SLAM technique to estimate head configuration and extract environmental information. Even in cases where the head moves dynamically, the proposed method could obtain 3D point-of-regard. Additionally, gaze trajectories are appropriately overlaid on the scene camera image.

The purpose of this study is to explore how the viewers’ previous training is related to their aesthetic viewing in various interactions with the form and the context, in relation to apparel design. Berlyne’s two types of exploratory behavior, diversive and specific, provided a theoretical framework to this study. Twenty female subjects (mean age=21, SD=1.089) participated. Twenty model images, posed by a male and a female model, were shown on an eye-tracker screen for 10 seconds each. The findings of this study verified Berlyne’s concepts of visual exploration. One of the different findings from Berlyne’s theory was that the untrained viewers’ visual attention tended to be more significantly focused on peripheral areas of visual interest, compared to the trained viewers, while there was no significant difference on the central, foremost areas of visual interest between the two groups. The overall aesthetic viewing patterns were also identified.
