Pre-diagnostic of visual acuity through a serious game

Serious games have been used successfully in the most diversified areas of Health Care. Taking advantage of the engagement and abstraction of reality provided by video games, the aim of this research was to develop a serious game capable of performing a visual acuity pre-diagnostic test in children aged between 3 and 7 years. Taking advantage of the potential of 3D sensors, both from the point of view of the ability to make accurate measurements, as well as using such information to create dynamic 3D content that reacts to the player's movement, a prototype that incorporates the LEA test specifications in a video game was built. The developed system was subjected to tests in a hospital environment, and encouraging results were obtained that pointed out the suitability of this type of game as a tool to aid in the diagnosis of visual acuity problems in very young children. Although there are conclusive results, it is assumed that the prototype should be complemented by future work and additional tests, by studying other regressive models and a larger number of participants.
