Resumen

Los procedimientos de evaluación de los sistemas alternativos de acceso al ordenador son poco rigurosos, sistemáticos y formales. Este trabajo presenta una metodología para la valoración de la interacción usuario-ordenador, cuando los sistemas de eye-tracking son utilizados como herramienta de acceso alternativo al ordenador por personas con Parálisis Cerebral (PC). Para ello, proponemos tres métricas de evaluación: tasa de fallos de calibración, tasa de error en el clic y tiempo de clic. Validamos la metodología, comparando 3 (tres) eye- trackers, con 9 (nueve) participantes con PC con trastornos motores severos. Los resultados indican que la calibración es un proceso crítico en estos escenarios como refleja la alta tasa de fallos de calibración medida. Los participantes con PC también tienen una alta tasa de error del clic, lo que indica que el uso de eye-trackers para alcanzar un objeto en pantalla es un proceso complejo para estos niveles de discapacidad motriz. Los tiempos de clics son similares entre todos los eye-trackers y participantes. Este trabajo pretende establecer líneas metodológicas para la efectiva evaluación de estos dispositivos, que pueden llegar a ser una interesante alternativa de acceso al ordenador para esta población.

Abstract

The procedures for evaluating alternative computer access systems are neither rigorous, systematic nor formal. We present a methodology to evaluate the user-computer interaction, based on three metrics, when people with cerebral palsy (CP) use eye- trackers as an alternative access device. We validated the methodology by comparing three commercial eye-trackers with nine participants seriously affected by CP. The results indicate that the calibration is a very critical process in these scenarios because of the high rate of calibration failures measured. The participants with CP also have a high click error rate, indicating that using eye- trackers to reach an object on the screen is a complex process for these levels of disability. The click times are similar between all eye-trackers and participants. This study is not intended to discourage the use of eye-trackers in the population with CP, but to establish methodological guidelines for the effective evaluation of commercial devices, which can be an interesting alternative to computer access for this population.
