Haptic Feedback for VR Environments S tudent - Michael Burke 201403540 1st S upervisor – Dr. Anthony Bateson 2nd S upervisor – Dr. Jon Purdy

Introduction • The aim for this proj ect was to create a “ haptic feedback device in a wearable, scalable manner” (Lindeman, 2003), in the form of a j acket that uses solenoids as a feedback medium, for use in virtual reality (VR) environments. The system described could potentially be used as “ a valuable training aid where training in real life situations would be impractical because, for example, it would be dangerous, logistically difficult, unduly expensive” (Rose, 2000).

Inspiration • The inspiration for this proj ect was to increase user engagement in virtual reality worlds through the use of haptic feedback. Inspiration for Haptic Jacket (www. blog.cloudhelix.io)

Background • A good haptic feedback system would provide valuable stimulus to the user, which should allow the user to feel more immersed in their chosen environment. • VR systems have become more immersive with technology, such as the Oculus Rift which is said to “ provide the user with experiences that were earlier thought to be merely a dream or nightmare.” (Dasai, 2014).

Concepts • Compressed air concept was discarded quickly since the idea of carrying an air compressor was large, impractical, expensive and noisy. • transducers; however, it was 12V Air Compressor (www.quadratec.com) discarded because of cost, size and safety matters. The transducers can also cause artifacts in medical devices. Micro Transducers used in a P300 study (H Y aj ima, 2014).

Aims & Objectives • Creating software for the Arduino µController • Creating a first person shooter (FPS ) virtual environment (VE) in Unity3D • Building hardware for Haptic Jacket • Testing VE and Hardware • Testing with human participant s to show levels of engagement (Ethics)

Project Management

Conclusion • The main focus of the proj ect was to make the VE more immersive to participants. • To measure of how immersive the environment is with and without haptic feedback. • The VE and j acket were fully built and tested together. • Human participant trail would have possibly shown more conclusive data.

Future Work • Improving Vest Feedback Zones • Larger Test Group (Ethics) • Design more Haptic Technology such as Arms, Gloves and Legs Future of VR, (www.conceptsvideo.com, 2018)

Problems • Originally a commercial game was going to be reverse engineered. • Human participant testing was going to take place, ethics were applied for.
