This paper describes the use of Reinforcement Learning in Immersive Virtual Reality to make a person move to a specific location in a virtual environment. Reinforcement Learning is a sub-area of Machine Learning in which an active entity called an agent interacts with its environment and learns how to act in order to achieve a pre-determined goal. The Reinforcement Learning had no prior model of behaviour...
The human visual system always focuses at a distinct depth. Therefore, objects that lie at different depths appear blurred, a phenomenon known as Depth of Field (DoF); as the user's focus depth changes, different objects come in and out of focus. Augmented Reality (AR) is a technology that superimposes computer graphics (CG) images onto a user's view of the real world. A commonly used AR display device...
We present the evaluation of EyeAR, a display with refocusable content based on user's eyes measurements. We carried out a user study to validate the prototype to verify that participants cannot distinguish between real and virtual objects. Participants looked at three pillars (one of which was virtual) placed at different distances from the user. They had to guess which pillar was the virtual one...
This paper describes the impact of display resolution and luminance on the responses of participants in a behavioral study that used a projection-based Immersive Virtual Reality System. The scenario was a virtual bar where participants witnessed a violent attack of one person on another due to an argument about support for a soccer club. The major response variable was the number of interventions...
