  After the introduction of smartphones and smartwatches, AR glasses are
considered the next breakthrough in the field of wearables. While the
transition from smartphones to smartwatches was based mainly on established
display technologies, the display technology of AR glasses presents a
technological challenge. Many display technologies, such as retina projectors,
are based on continuous adaptive control of the display based on the user's
pupil position. Furthermore, head-mounted systems require an adaptation and
extension of established interaction concepts to provide the user with an
immersive experience. Eye-tracking is a crucial technology to help AR glasses
achieve a breakthrough through optimized display technology and gaze-based
interaction concepts. Available eye-tracking technologies, such as VOG, do not
meet the requirements of AR glasses, especially regarding power consumption,
robustness, and integrability. To further overcome these limitations and push
mobile eye-tracking for AR glasses forward, novel laser-based eye-tracking
sensor technologies are researched in this thesis. The thesis contributes to a
significant scientific advancement towards energy-efficient mobile eye-tracking
for AR glasses.
