SynTec: A Low-Cost Eye-Tracking and EEG-Based Diagnostic System for Concussion Assessment in Sports

Abstract: Concussions are a common form of mild traumatic brain injury (mTBI), particularly among athletes in high-impact sports. Existing diagnostic tools such as SCAT, VOMS, and EEG are limited by cost, subjectivity, or complexity. This paper presents SynTec, a novel wearable system that integrates eye-tracking and EEG technologies to support concussion screening in a compact, affordable format. A user-centered design process was employed, including stakeholder interviews, surveys (n=36), and iterative prototyping. The device supports vestibular and ocular motor assessments through eye-tracking and records electrical brain activity from frontal regions using low-cost EEG sensors. Results are processed via an accompanying mobile application. SynTec demonstrates a new direction for rapid, accessible, multi-modal concussion diagnostics, particularly for youth and amateur sports.
