Abstract

A physical and cognitive field-testing apparatus with a touchscreen display, second display facing opposite direction, Internet communication, local processor, accelerometer. Interactive window displays graphic artifacts for balancing and coordination tests. Eye-tracking via camera.

Key technical features

• Brain recording: NO — no EEG, no electrodes, no ERP; uses touchscreen interaction, accelerometer (balance), camera (eye tracking)
• Species: Human — 9 “human” mentions; 35 “user”; 25 “subject”; 3 “patient”; 0 animal/rodent/primate
• Tests: Balance (accelerometer), reaction time (touchscreen), coordination (S-curve tracking), recollection, sequence memory, pattern recognition, color recognition (Stroop), impulse control, problem solving, eye movement tracking (camera), memory
• Platform: Portable tablet (iPad/Galaxy Tab) or smartphone (iPhone/Nexus)
• Purpose: Acute concussion / mild traumatic brain injury (MTBI) diagnosis on-field
• Classification: A61B5/16 (psychotechnics), A61B5/162 (reaction time), A61B5/163 (eye movement/gaze/pupil), A61B5/165 (depression/anxiety), G09B5/02 (educational appliances)

Claims (10 claims)

1. Field-testing apparatus with first + second display, Internet, processor, software; interactive window with graphic artifacts for balancing + coordination tests; accelerometer.
2. Touchscreen with moving graphic for hand coordination tracking.
3. S-curved line snaking back and forth.
4. Snake back and forth more rapidly over time.
5. Additional artifacts appearing one-at-a-time for reaction time.
6. Detects touches outside predefined boundaries.
7. Threshold of out-of-boundary touches to discontinue test.
8. Image capturing device facing away from first display for eye movement tracking.
9. Timer records time devoted to interaction.
10. First artifact = circle, second = smaller, keep within circle.

Significance

A behavioural-only portable cognitive assessment system — no brain recording. Uses touchscreen + accelerometer + camera for concussion/MTBI field testing. The 12-test battery (balance, reaction, coordination, recollection, sequence, pattern, color, impulse, problem-solving, eye tracking, memory) is a comprehensive portable CANTAB-like system for sports/field medicine.
