This paper investigates a prototype of an interaction design for a flexible natural language user interface with a minimal set of gestures and natural language commands. The prototype is evaluated using a Hi-Fi simulation approach that allows the enactment of an interfaces that accommodates gesture and speech input for directive commands. In the scenario users were guiding a robot equipped with a...
Autonomous robot navigation has many applications such as space exploration and autonomous vehicles. Currently, such navigation is ensured by the use of multiple sensors which may hinder quick commercialization. In this article, we propose a solution for navigating a robot in an unknown environment using only monocular vision algorithms.
This work addresses the use of optical flow to supervise the navigation of mobile robot. The optical flow information is computed from the images sequence in order to be used in the navigation algorithm. The optical flow provides very important information about the robot environment, like: the obstacles disposition, the robot heading, the time to collision and the depth. The use of this information...
