Design Brief

• Client: Ophthalmologists / Visually Impaired Patients
• Goal: Design and build a digital vision exam providing an approximate assessment of visual acuity. The exam should be completed within 5 minutes using a simple calibration headset.

Measurable Constraints:

• The visual acuity result should be within 1-2 optotype rows of actual acuity.
• The test should be completable within 5 minutes.
• The optotype size should be within 2 mm of the actual size.
• The headset should be compact (max 5” x 6”) and lightweight (< 0.55 lbs) with an affordable material cost of $6 or less.
• Designed to fit head circumferences from 20” to 25”.
• Operates in temperatures between 0°C and 40°C.
• Assembly time for the headset should not exceed 3 minutes.
