Healthcare & Sports Technology
Mobile Vision Assessment & Concussion Monitoring App
Overview
Athletes and sports organizations needed a reliable, accessible way to assess visual performance and detect potential concussion related changes over time. Traditional vision testing methods were often manual, inconsistent, and difficult to track longitudinally, limiting their usefulness in fast paced sports environments. To address these challenges, Locaze was designed as a mobile application offering a standardized suite of guided vision tests, establishing baseline eyesight data and enabling easy comparison over time to support safer return to play decisions.
The Challenge
Athletes and sports organizations faced significant barriers in consistently assessing and monitoring visual health, a critical yet often overlooked component of concussion diagnosis.
Inconsistent Testing Methods
Manual vision tests varied by practitioner, making reliable baseline comparisons impossible.
No Longitudinal Tracking
Without standardized data capture, detecting visual changes over time or post incident was guesswork.
Slow Sideline Assessment
Existing tools were clinic based and too slow or impractical for real world sports environments.
Limited Return to Play Confidence
Medical staff lacked objective visual data to support informed return to play decisions.
No Automated Retest Workflows
Failed or borderline tests had no structured path for follow up, leaving gaps in athlete safety protocols.
Our Solution
Locaze delivers a guided, standardized mobile assessment suite that makes professional grade vision testing accessible on any smartphone, on the sideline, in the locker room, or at home.
Guided Vision Test Suite
Six structured tests, Calibration, Accommodation, Optokinetic Nystagmus, Saccades, Smooth Pursuit, and Vestibular Ocular Reflex, each with step by step in app instructions.
Baseline Establishment
First use assessments capture individual athlete benchmarks, creating a personal reference point for all future comparisons.
Automated Pass/Fail & Retest
Test results are scored automatically; any failed assessment immediately triggers a structured retest workflow to confirm outcomes.
Longitudinal Comparison Engine
All results are stored with timestamps, enabling side by side comparisons between baseline and post incident assessments.
Role Based Access
Athletes, coaches, and medical staff each have tailored views, athletes see their results, medical staff access full team history and trend data.
The Six Vision Tests
Each test targets a distinct aspect of visual function. A failed result automatically triggers a guided retest before results are logged.
Calibration
Establishes screen to eye reference point for accurate test delivery.
Accommodation Test
Measures the eye's ability to shift focus between near and far targets.
Optokinetic Nystagmus Test
Evaluates involuntary eye movement in response to moving visual stimuli.
Saccades Test
Assesses rapid, precise eye jumps between distinct fixation points.
Smooth Pursuit Test
Tests ability to smoothly track a slowly moving target across the visual field.
Vestibular Ocular Reflex Test
Checks the coordination between head movement and eye stabilization.
Technical Implementation
A mobile first architecture built for reliability, accuracy, and ease of use in demanding sports environments.
Mobile Application
Cross platform mobile app (iOS & Android) optimized for athlete and sideline use, intuitive guided flows, minimal setup, and consistent test delivery across devices.
Standardized Test Engine
Six structured vision assessments (Calibration, Accommodation, Optokinetic Nystagmus, Saccades, Smooth Pursuit, Vestibular Ocular Reflex) with automated scoring and pass/fail logic.
Baseline & Retest Logic
Establishes individual athlete baselines on first use; flags deviations on follow up tests and automatically triggers retest workflows for failed assessments.
Longitudinal Data Tracking
Stores timestamped test results per athlete, enabling side by side baseline to current comparisons and trend analysis over time.
Cloud Based Backend
Secure data storage with role based access for athletes, coaches, and medical staff, real time sync across devices with full audit history.
