Abstract : Nowadays, Virtual Reality (VR) technologies are rapidly advancing as they address new domains such as therapy. Preliminary studies suggest that VR has enormous potential for reducing acute pain during wound care. However, state-of-art VR analgesia systems currently require patients to move a handheld input device. Unfortunately, many severe pediatric burn patients trying to use VR have burned hands and are unable to use a handheld mouse. The main project of this research aims to solve a limitation in existing VR analgesic systems by increasing the illusion of presence and analgesic effectiveness for immobilized children by adding eye-tracking capability for the first time. After exploring the different eye-tracking technologies, investigating the feasibility of using eye tracking in active or passive forms, and evaluating people’s awareness of and attitude toward such technology, an eye-tracking system was developed using an improved control interface to increase interactivity in the VR environment. The research explores the technical requirements of the developed system, in which the recent innovation of an embedded eye tracker in a VR helmet is utilized to implement a laboratory pain distraction system. In order to assess the effectiveness of the system, a randomized controlled laboratory analog pain study was conducted with healthy volunteers to quantify whether using eye movements to interact in a VR system significantly increases the illusion of presence and increases the analgesic effectiveness of VR distraction during brief thermal pain. Additionally, we designed a fixation detection algorithm that executes within the immersive VR technology, as a step toward another future approach of using eye tracking passively in order to collect eye movements to assess the patient’s mental state during painful medical procedures.
