1. Vision Integrated Electric Wheelchair Kit (VIEW Kit) Team Wheelchair Visionaries (12) Siddharth Kuncham, Douglass Roman, Peter Arriaza, Neil Zhang Team 12: Wheelchair Visionaries

2. Problem Over 180,000 Americans are classified as Quadriplegic 12,500 new injuries a year Almost all quadriplegic patients have neck mobility Electric Wheelchairs cost around $1900 - $30,000+ Weigh around 250-300+ pounds Team 12: Wheelchair Visionaries

3. Purpose Motorized Attachment Kit for Manual Wheelchairs Controlled by eye and neck movement Provide quadriplegic patients with a cheaper and easier option to regain mobility Lighter, more portable, and more versatile Team 12: Wheelchair Visionaries

4. Existing Solutions - Conversion Kits E-Motion Power System Light Drive Team 12: Wheelchair Visionaries

5. Existing Solutions - Eye Tracking Infrared SensorsCamera Team 12: Wheelchair Visionaries

6. Why the VIEW Kit? Provides integration of conversion kits and eye tracking systems Simple to install, adjustable, used for different types of wheelchair Significantly lower in price Team 12: Wheelchair Visionaries

7. Wheelchair Comparison Manual Pros easy to transport lightweight lower maintenance Cons requires arm strength to move difficult for slopes Power Pros allows those with difficulty propelling wheelchair to move adequately increased freedom Cons high cost heavy difficult to transport requires charging higher maintenance Team 12: Wheelchair Visionaries
