Haptic Gaming System

Overview

Haptikos is an interactive gaming system that allows the user to physically feel a virtual world. The player controls the cursor by moving the red joystick. Two games were created to test the feedback system. The first, the player assumes the character of LINK (from Zelda) and jumps through a side-scrolling level collecting rupees and avoiding red boxes. The second involves feeling out the virtual shape with nothing other than a blue position dot and a blank screen. The answer can be seen by pushing R.

Exisiting System

The system was a modification from a previous pentagraph configuration. This allows for the free point to be able to freely move in a fixed two-dimensional plane. There are two Canon TR-36 optical encoders with a 3600 count/rev in x1 mode mounted on top of the stationary pivot.(see below) They are used to track the angle of the larger bars and calculate the position of the free point.
