* 1. Which of the following best describes your level of vision?

* 2. How much do you walk on a given day?

* 3. Do you currently have a device to assist walking, such as a cane or guide dog? If so what type of assistance do you use?

* 4. Thinking back to the past week, have you walked into any objects at waist level or above? (such as tree branches)

* 5. If you answered yes to the previous question, how often did you walk into objects above waist level?

* 6. We are currently designing a pair of glasses that use ultrasonic sensors to detect nearby objects or obstacles and notifying the user through a vibration to either the left, center, or right side of the chest in a vest or suspenders, depending on where the obstacle is located. The glasses would be able to detect a obstacle from up to 2 meters away, and the vibration would increase the closing you were to the object. The device battery would last at least 8 hours, and would be powered by two rechargeable AA batteries.

Given these product features, how much interest would you have in the device on a scale of 1 - 5?

* 7. How important are the following features of the device? Please answer using a 7-point scale where 1 means “not at all important” and 7 means “extremely important.”

  1 (Not at all Important) 2 3 4 5 6 7 (Extremely Important)
Vibration Response
Light Weight
Long Battery Life

* 8. If the device were on the market, do you think you would buy it?

* 9. At what price would you think that the device would be a good value?

* 10. Do you have any comments or concerns about the device?
