Voice navigation systems allow users to interact with computer applications by voice. In this paper we present human factors research that evaluated design alternatives for major user interface components. In the first study we evaluated the appropriateness and discriminability of four sets of icons that were candidates for functions in theVoice To...

This paper involves the design and development of an improved Ant Colony Optimization algorithm for the purpose of robot navigation. The algorithm is able to calculate optimum paths for the robot to travel on to perform the tasks of goal-seeking, wall-following and obstacle avoiding, where the efficiency of a path is determined based on the length...
