With the advancement in technology, there have been new technologies that enables a more immersive gaming experience for the user. Even though these new technologies offer more immersive experiences, they are still not truly immersive as there is a disconnect between the environment that the user sees in the virtual reality headset and the environment that the user is feeling under their feet. This created the motivation of this project by trying to overcome this disconnect through replicating the feel of different ground types through the use of a pin and spring system and to be able to replicate the topography of the environment through the adaption of dynamic shape technology.

Throughout this project different spring configurations were tested to investigate the viability of using springs to replicate the different ground feels. This was done through creating a test rig that displayed different spring configurations that included one spring and two spring configurations in different gauges in a single layer and three spring configurations in different gauges positioned in a dual layer. The test rig was then graded on a scale of one to five with one being the hardest feeling surface and five being the softest and was tested at different compression states (fully uncompressed, half compressed and fully compressed) to determine the feel of each compression stage. The topography test was to test the viability of the integration of the two systems through testing how well the system performed under force and no force at various speeds.

The outcome of the tests concluded that the configurations that used three springs were the most stable but also the stiffest and hence was not viable. It was decided that for the scaled prototype, the best spring to be able to replicate different ground types was a 3/8” x 5/8” gauge spring in a single layer configuration that utilised only a single spring. The topography tests concluded that the motor chosen for the prototype was not able to withstand forces being placed on the system and hence different motor and actuation methods would need to be considered. It was determined that the viability of the two systems together was acceptable as they operated independently of each other and hence did not influence each other. Integration of these systems to virtual reality treadmills should be achievable if pin size and layout, motor size and power and computational needs are considered. Further investigations are required prior to a full scale model is achievable.
