Teresa Hirzle, M. Sc.

Teresa Hirzle ist der HCI Gruppe im Juni 2017 als wissenschaftliche Mitarbeiterin und Doktorandin beigetreten. Davor war sie seit 2011 Studentin der Medieninformatik an der Universität Ulm. Während ihres Studiums verbrachte sie zwei Semester an der Universidad de Granada, Spanien.

Teresa hat einen M. Sc. in Medieninformatik (2017) von der Universität Ulm. Der Titel der Masterarbeit lautete: Towards Eyes Only Interaction in Virtual Reality. Die Arbeit wurde am Institut für Medieninformatik in Kooperation mit dem Institut für Allgemeine Psychologie durchgeführt (Cogain 2017).

A Symbiotic Human-Machine Depth Sensor

The goal of this project is to explore how much we can learn about physical objects a user is looking at by observing gaze depth. We envision a symbiotic scenario, where current technology (e.g. depth cameras) is extended with "human sensing data". Here, a depth camera is able to create a rough understanding of a static environment and gaze depth is merged into the model by leveraging unique propetries of human vision.


A Design Space for Gaze Interaction on Head-Mounted Displays

Augmented and virtual reality (AR/VR) head-mounted display (HMD) applications inherently rely on three dimensional information. In contrast to gaze interaction on a two dimensional screen, gaze interaction in AR and VR therefore also requires to estimate a user's gaze in 3D (3D Gaze).

While first applications, such as foveated rendering, hint at the compelling potential of combining HMDs and gaze, a systematic analysis is missing. To fill this gap, we present the first design space for gaze interaction on HMDs.
