Desarrollo de una interfaz VR y un dispositivo portable, enfocados a personas no videntes, para generar una retroalimentación háptica, permitiendo identificar geometrías 3D regulares

Abstract

This degree work was carried out with the aim of solving a possible need for impaired people, specifically covers the identification of regular virtual three-dimensional figures through haptic feedback from a portable device. For the development, a VR application was developed in UNITY in which libraries of the Leap Motion device can be imported for hand tracking, then we started with the design of the circuits and the physical part that protects them. Once the software and hardware were developed, the wireless connection (Bluetooth) between the application and the portable device was made. Once the operation was verified, tests were carried out to determine the volume projected by the haptic feedback on the workspace of the Leap Motion device, which resulted in an almost perfect interpretation of the analyzed geometry. During the user tests with blind people, it was possible to establish the difficulty present when trying to identify a figure with a single point of reference such as the feedback on the right index finger.
