My research is devoted to investigating facts and developing tools to help the rehabilitation of people with low vision, especially those with macular vision loss.

Haptic Kinematics of Two-Handed Braille Reading in Blind Adults
This page (currently under construction) accompanies a work-in-progress poster at the 2020 Eurohaptics meeting.
Regressions in Braille Reading
This project explores regressions (movements to re-read text) in braille reading. The image on the right plots the braille reading finger movements in blue and regressions in black.
Micro-Perimetry by Scanning Laser Ophthalmoscope
We developed software to make the retinal placement of stimuli during micro-perimetry by a scanning laser ophthalmoscope (SLO) independent of involuntary fixational eye movements. This greatly increases the accuracy of the measurement and enhances the ability to reliably repeat...
Motion as a Cue for Attention
We investigated whether relative motion can serve as a cue for sustained...
Focal Attention and Letter Recognition
We studied letter recognition in 8 deg eccentricity from the fovea after attracting sustained focal attention to the stimulated location by a cue. Young and elderly healthy subjects, as well as patients with central vision loss participated. We found that the ability to utilize...
Reading with the Retinal Periphery
Typographical features of letters were manipulated in such a way that frequently occurring letter confusions in eccentric viewing happened less frequently. This demonstrated that a combination of psychophysics and goal-directed modification of typographic features is a viable...
We studied the ability of dyslexic young teenagers to fluently name pictograms (shapes of objects). We found that some dyslexics are very good at this task, some were even better than the control subjects.
We also investigated whether dyslexics make...
Reading Random Word Sequences (The SKread Test)
This vision test shows random word sequences that prevent the prediction of upcoming words by linguistic criteria and is simple to score in a clinical setting.
It combines the standardized format of the MNread test with sequences of random words and...
The Kinematics of Braille Reading
When blind persons read braille, a system of raised dots for tactile reading and writing, how is the information processed? How do a few indentations on the fingerpads translate to linguistic information, and how does the text, in turn, influence the motions of the...
