Motion correlation: selecting objects by matching their movement (2017)
Journal Article
Velloso, E., Carter, M., Newn, J., Esteves, A., Gellersen, H., & Clarke, C. (2017). Motion correlation: selecting objects by matching their movement. ACM transactions on computer-human interaction, 24(3), Article 22. https://doi.org/10.1145/3064937

Selection is a canonical task in user interfaces, commonly supported by presenting objects for acquisition by pointing. In this article, we consider motion correlation as an alternative for selection. The principle is to represent available objects b...

TraceMatch: a computer vision technique for user input by tracing of animated controls (2016)
Presentation / Conference Contribution
Esteves>, A., Clarke, C., Bellino, A., Esteves, A., Velloso, E., & Gellersen, H. (2016). TraceMatch: a computer vision technique for user input by tracing of animated controls. In UbiComp '16 Proceedings of the 2016 ACM International Joint Conference on

Recent works have explored the concept of movement correlation interfaces, in which moving objects can be selected by matching the movement of the input device to that of the desired object. Previous techniques relied on a single modality (e.g. gaze... Read More about TraceMatch: a computer vision technique for user input by tracing of animated controls.

AmbiGaze: Direct Control of Ambient Devices by Gaze (2016)
Presentation / Conference Contribution
Velloso, E., Wirth, M., Weichel, C., Esteves, A., & Gellersen, H. (2016, June). AmbiGaze: Direct Control of Ambient Devices by Gaze. Presented at Proceedings of the 2016 ACM Conference on Designing Interactive Systems - DIS '16

Eye tracking offers many opportunities for direct device control in smart environments, but issues such as the need for calibration and the Midas touch problem make it impractical. In this paper, we propose AmbiGaze, a smart environment that employs... Read More about AmbiGaze: Direct Control of Ambient Devices by Gaze.

Beats: Tapping Gestures for Smart Watches (2015)
Presentation / Conference Contribution
Oakley, I., Lee, D., Islam, M. R., & Esteves, A. (2015). Beats: Tapping Gestures for Smart Watches. In Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems (1237-1246). https://doi.org/10.1145/2702123.2702226

Interacting with smartwatches poses new challenges. Although capable of displaying complex content, their extremely small screens poorly match many of the touchscreen interaction techniques dominant on larger mobile devices. Addressing this problem,... Read More about Beats: Tapping Gestures for Smart Watches.

Fall of Humans: Interactive tabletop games and transmedia storytelling. (2015)
Presentation / Conference Contribution
Dionisio, M., Gujaran, A., Pinto, M., & Esteves, A. (2015). Fall of Humans: Interactive tabletop games and transmedia storytelling. In Proceedings of the 2015 International Conference on Interactive Tabletops & Surfaces (401-404). https://doi.org/10.1145

This paper illustrates how transmedia storytelling can help introduce players to interactive tabletop games. To do so, we developed Fall of Humans (FoH), an experience that takes place over two games: Meat factory, a physical card game where players...

Orbits: enabling gaze interaction in smart watches using moving targets (2015)
Presentation / Conference Contribution
Esteves, A., Velloso, E., Bulling, A., & Gellersen, H. (2015). Orbits: enabling gaze interaction in smart watches using moving targets. In UbiComp/ISWC'15 Adjunct Adjunct Proceedings of the 2015 ACM International Joint Conference on Pervasive and Ubiquit

In this paper we demonstrate Orbits, a novel gaze interaction technique that accounts for both the reduced size of smart watch displays and the hands-free nature of conventional watches. Orbits combines graphical controls that display one or multiple... Read More about Orbits: enabling gaze interaction in smart watches using moving targets.

Orbits: gaze Interaction for smart watches using smooth pursuit eye movements. (2015)
Presentation / Conference Contribution
Esteves, A., Velloso, E., Bulling, A., & Gellersen, H. (2015, November). Orbits: gaze Interaction for smart watches using smooth pursuit eye movements. Presented at 28th Annual ACM Symposium on User Interface Software & Technology

We introduce Orbits, a novel gaze interaction technique that enables hands-free input on smart watches. The technique relies on moving controls to leverage the smooth pursuit movements of the eyes and detect whether and at which control the user is l...

The ATB Framework: quantifying and classifying epistemic strategies in tangible problem-solving tasks. (2015)
Presentation / Conference Contribution
Esteves, A., Bakker, S., Antle, A., May, A., Warren, J., & Oakley, I. (2015, January). The ATB Framework: quantifying and classifying epistemic strategies in tangible problem-solving tasks. Presented at 9th International Conference on Tangible, Embedded

In task performance, pragmatic actions refer to behaviors that make direct progress, while epistemic actions involve altering the world so that cognitive processes are faster, more reliable or less taxing. Epistemic actions are frequently presented a... Read More about The ATB Framework: quantifying and classifying epistemic strategies in tangible problem-solving tasks..
