Abstract
Visual noisetag brain computer interfaces (BCIs) are brain controlled devices that allow
users to communicate or control other devices (e.g. a TV). These BCIs particularly
give patients with certain forms of paralysis the opportunity to communicate and be
independent. Unfortunately it can be annoying and exhausting to look at the
ashing
stimulus, currently used in these BCIs. This thesis aims to optimize the user experience
of these BCIs by using moving textures as stimuli. Hoping to obtain a stimulus
that increases pleasantness and decreases fatigue. To achieve this participants rated a
collection of moving textures, and some interesting ones were tested on performance
by integrating them in a visual noisetag BCI. Results show that although the moving
stimuli are subjectively preferred over the
ashing stimulus, they cannot maintain the
high performance of the BCI with the
ashing stimulus. Despite these ndings adding
motion can still be promising to optimize the user experience of a visual noisetag BCI,
but more research is needed on the generation and processing of the responses.
