Eye movements are the least affected by disabilities of the central motor system. This means that eye movements
have great potential in the development of applications adapted to people with motor disabilities. This article
describes the development of an electrooculography (EOG) system to control a serious computer game. The goal
is to allow people with motor disabilities to play a serious game and improve control over their oculomotor
systems. The developed system consists of three subsystems: a low-cost hardware device to acquire the EOG
signals, methods to process them digitally, and a serious game controlled exclusively by eye movements.
Fourteen able-bodied volunteers of different ages and genders tested the computer game. The evaluation of the
system’s interaction capacity with the computer game was based on three metrics: score obtained, number of
successful interactions, and number of errors committed.
