Comparative Studies of the Variations in the Spatial Location Processes Generated by a Weak-Visual Person in Two Works Systems

Abstract

Weak-visual users carry out various types of temporary interaction processes through a wide range of work systems to perform heterogeneous activities of daily living as well as to obtain specific information. One of the processes that are more complicated for a weak-visual person, by the investment of time as well as the activation of various sensory mechanisms, is the spatial location. It has been detected, through static network techniques, a difference in the hierarchy of the temporal micro-processes that the Weak-Visual person performs in the interaction with two different work systems, in this sense, it was observed that the spatial location for the weak-visual person can be originated by two kinds of processes: from the Sound Interaction (Is) and the motor exploration (Img). In the interaction processes executed by the weak-visual person, it was observed that the user could make a spatial location in work systems started with the sound interaction. In this process of interaction, a lower activation of sensory mechanisms were observed. On the other hand, in work systems that involved a motor exploration were observed a greater activation of sensory mechanisms. In the same way, it was perceived that work systems that promote spatial location starting with Is generates more time in the precise location of virtual objects., While work systems that promote spatial location from motor exploration generates higher levels of stress. Our objective is to reflect on the analysis of those patterns that can generate a better interaction in the relationship: Weak-visual person - Work devices, to improve the execution of the activities of these users in a precise and autonomous way.
