Discerning Ambient/Focal Attention with Coefficient K
Krzysztof Krejtz, Andrew Duchowski, Izabela Krejtz, Agnieszka Szarkowska, Agata Kopacz
Article No.: 11
DOI: 10.1145/2896452

We introduce coefficient K, defined on a novel parametric scale, derived from processing a traditionally eye-tracked time course of eye movements. Positive and negative ordinates of K indicate focal or ambient viewing,...

3D Blur Discrimination
Mahesh M. Subedar, Lina J. Karam
Article No.: 12
DOI: 10.1145/2896453

Blur is an important attribute in the study and modeling of the human visual system. In the blur discrimination experiments, just-noticeable additional blur required to differentiate from the reference blur level is measured. The past studies on...

Color Picking: The Initial 20s
Jan Koenderink, Andrea Van Doorn, Vebjørn Ekroll
Article No.: 13
DOI: 10.1145/2883613

Color pickers are widely used in all kinds of display applications. They vary greatly in their utility, depending on user expertise. We focus on nonprofessional, occasional users. Such users may spend from a few seconds up to a few minutes to...

Individual Differences in Image-Quality Estimations: Estimation Rules and Viewing Strategies
Jenni Radun, Mikko Nuutinen, Tuomas Leisti, Jukka Häkkinen
Article No.: 14
DOI: 10.1145/2890504

Subjective image-quality estimation with high-quality images is often a preference-estimation task. Preferences are subjective, and individual differences exist. Individual differences are also seen in the eye movements of people. A task's...

Reconstructing User’s Attention on the Web through Mouse Movements and Perception-Based Content Identification
Paolo Boi, Gianni Fenu, Lucio Davide Spano, Valentino Vargiu
Article No.: 15
DOI: 10.1145/2912124

Eye tracking is one of the most exploited techniques in literature for finding usability problems in web-based user interfaces (UIs). However, it is usually employed in a laboratory setting, considering that an eye-tracker is not commonly used in...

Using Audio Cues to Support Motion Gesture Interaction on Mobile Devices
Sarah Morrison-Smith, Megan Hofmann, Yang Li, Jaime Ruiz
Article No.: 16
DOI: 10.1145/2897516

Motion gestures are an underutilized input modality for mobile interaction despite numerous potential advantages. Negulescu et al. found that the lack of feedback on attempted motion gestures made it difficult for participants to diagnose and...

Distinguishing between Abstract Art by Artists vs. Children and Animals: Comparison between Human and Machine Perception
Lior Shamir, Jenny Nissel, Ellen Winner
Article No.: 17
DOI: 10.1145/2912125

Abstract expressionism is a school of art characterized by nonrepresentational paintings where color, composition, and brush strokes are used to express emotion. These works are often misunderstood by the public who see them as requiring no skill...
