The Macular Mapping Test
The Macular Mapping Test (MMT) is a tool for the assessment of the topography of vision. It is a quick and low-cost alternative to conventional perimetry in practical low vision care.

The Macular Search Test
We introduced a novel approach to topographic function assessment in visual impairment that requires neither fixation nor reading.

The Window of Spatial Attention in Reading
In reading, visual information is extracted from a window around the gaze. For the first time, I looked at effects of word's processing load on the dynamics of this window over the course of a fixation when sequential saccades are made.

Tracking a target in depth with central field loss
Bilateral field loss due to maculopathy creates a scotoma that extends in depth — a volume scotoma.

Upper Depth Limit Across Visual Field
Stereopsis is important for tasks of daily living such as eye-hand coordination. It is best in central vision but is also mediated by the periphery.

Video-Based Speech Enhancement for Persons with Hearing and Vision Loss
Observing the visual cues from a speaker such as the shape of the lips and facial expression can greatly improve the speech comprehension capabilities of a person with hearing loss. However, concurrent vision loss can lead to a significant loss in speech perception. We propose developing a prototype device that utilizes a video camera in addition to audio input to enhance the speech signal from a target speaker in everyday situations.
