“…Pursuit-based interaction is established by matching the trajectories of eye-movement to moving object trajectories on a display (Vidal, Bulling, & Gellersen, 2013). Different types of trajectories can be used, e.g., circular trajectories (Esteves, Velloso, Bulling, & Gellersen, 2015;Niu et al, 2021), linear trajectories (Porta, Dondi, Pianetta, & Cantoni, 2021;Zeng, Neuer, Roetting, & Siebert, 2022;Zeng & Roetting, 2018;Zeng, Siebert, Venjakob, & Roetting, 2020), and irregular trajectories such as an object's outline (Sidenmark, Clarke, Zhang, Phu, & Gellersen, 2020). In comparison to the other gaze interaction methods mentioned above, pursuit-based gaze interaction does not require precise gaze coordinates or personal calibration for a robust gaze-based interaction.…”

Gaze input, i.e., information input via eye of users, represents a promising method for contact-free interaction in human-machine systems. In this paper, we present the GazeVending interface (GaVe), which lets users control actions on a display with their eyes. The interface works on a regular webcam, available on most of today's laptops, and only requires a short one-point calibration before use. GaVe is designed in a hierarchical structure, presenting broad item cluster to users first and subsequently guiding them through another selection round, which allows the presentation of a large number of items. Cluster/item selection in GaVe is based on the dwell time, i.e., the time duration that users look at a given Cluster/item. A user study (N=22) was conducted to test optimal dwell time thresholds and comfortable human-to-display distances. Users' perception of the system, as well as error rates and task completion time were registered. We found that all participants were able to quickly understand and know how to interact with the interface, and showed good performance, selecting a target item within a group of 12 items in 6.76 seconds on average. We provide design guidelines for GaVe and discuss the potentials of the system.

“…Increasingly complex human-computer systems have put forward higher requirements for operators, making people realize the value of human-computer interaction research. The development and application of interactive methods, such as voice control, gesture recognition, brain-computer interfaces, eye tracking, and emotion recognition, have improved users' human-computer interaction experience in different scenarios (Cowie et al, 2001;Niu et al, 2023). The eye-control system is a human-computer interaction system in which the user outputs control instructions to the computer through eye movements, such as gaze, eye gestures, smooth tracking, and eye blinks.…”

Eye-tracking technology brings a different human-computer interaction experience to users because of its intuitive, natural, and hands-free operation characteristics. Avoiding the Midas touch problem and improving the accuracy of interaction are among the main goals of the research and development of eye-control systems. This study reviews the methods and limitations of research on avoiding the Midas touch problem. For typical control clicking operations with low fault tolerance, such as mode switching and state selection in an eye-control system, this study proposes Magilock, a more reliable control triggering method with a high success rate in multi-channel eye-control systems. Magilock adds a control pre-locked mechanism between the two interactive steps of eye-control channel positioning control and other interactive channel triggering controls in the multi-channel eye-control system. This effectively avoids incorrect control triggering caused by multi-channel coordination disorder and gaze-point drift. This study also conducted ergonomic experiments to explore the lock and unlock times of the control pre-locked mechanism in Magilock. Taking into account the experimental data and subjective evaluation of the participants, we recommend setting the lock time and the unlock time of Magilock to 200 ms.

“…Spatial layout factors affecting icons’ visual search include color matching, arrangement, and target location. The eye smooth pursuit study by Euclidean algorithm pointed out that the variable in the center position has the greatest influence on the tracking efficiency ( Niu et al, 2021 ). When the navigation panel is located in different positions on the screen, it will impact the users’ visual search performance.…”

Color and spatial layout are important factors that affect users’ icon cognition and play a huge role in the visual search process of icons. Guided by the user’s interactive needs, this paper aims to improve the visual search efficiency of mobile map navigation icons. The mixed design within and between subjects is adopted through the combination of theoretical and experimental research, and the subjective questionnaire method is used to explore the research. This paper explores the visual search problem of mobile map navigation icons based on color coding and layout coding. The experimental results mainly include reaction time, accuracy rate, user experience, and statistical and variance analysis. The results show that the layout of the mobile map navigation icons significantly impacts the user’s visual search. The navigation icons that use color for layout coding have the highest visual search efficiency and better user experience. Among the icons, the layout with regular color distribution and a larger area of the same color has the highest visual search efficiency for users and the best user experience; the visual search efficiency of navigation icons using color for layout coding is significantly higher than that of mobile map navigation icons.Relevance to industry: The user scale of mobile information maps is huge and the usage rate is high, but the large number of navigation icons increases the burden of user information identification and acquisition. As a result, the efficiency of user information acquisition is low, and the user experience is reduced. A clear, easy-to-search navigation icon design can enhance the user experience of the entire product. The results of this research provide theoretical support and practical guidance for the design optimization and improvement of mobile map navigation icons.
