A fun project to develop a game, that can be considered the most fun game for eye-tracking! It’s a tabletop UI where we attached two Tobii eyex trackers. The game has some interesting concepts: what if users look at the same target? What if they don’t?

Another design space exploration for gaze input. Here it’s about how gaze can support touch interaction on tablets. When holding the device, the free thumb is normally limited in reach, but can provide an opportunity for indirect touch input. Here we propose gaze and touch input, where touches redirect to the gaze target. This provides…

What is partially indirect? It’s about a new way of interacting with two hands: one does direct input via a pen, and the other indirect via touch & gaze. This paper provides an in-depth study to investigate this constellation.

Most input devices, be it mouse, pen, touch, are already extensively investigated and have become a big part of everyday life. Rather than adding a new UI mode, gesture, or some additional sensors, how can we make all of them substantially more expressive? Here we explore the idea of Gaze-shifting, using gaze to add an…

Building a system and app to showcase some really cool possibilities when using two eye trackers. Together, users can search hotels on a large map – both their gaze is indicated, in order to improve the user’s teamwork.

An early study I’ve conducted to better understand how gaze and touch compare. The old system made it a bit difficult to compare, but overall got some good indications on user performance. For dragging, gaze+touch is bad, but its quite comparable for scaling and rotation tasks.

How can we use the eyes better in existing user interfaces? Here we explore gaze input to complement multi-touch for interaction on the same surface. We present gaze-touch, a technique that combines the two modalities based on the principle of ‘gaze selects, touch manipulates’. Gaze is used to select a target, and coupled with multi-touch…

Fighting one of the biggest problems of eye trackers: calibration! For each individual user, eye trackers need to be calibrated which makes them just not usable for anything out of the lab. Here we propose a moving target calibration which allows to calibrate users implicitly, reliably, and without them even knowing.

Eye-based interaction has commonly been based on estimation of eye gaze direction, to locate objects for interaction. We introduce Pursuits, a novel and very different eye tracking method that instead is based on following the trajectory of eye movement and comparing this with trajectories of objects in the field of view.

My bachelor thesis project, looking at mid air pointing on a projection. The unique thing is the mobile projector that is attached to a phone, following up on the vision of future phones that can project any screen, anywhere! Learned lots about studies and Fitts Law here, and got interested in interaction design.
