2. Question
Identify the potential (possible) market, establish customer needs, and then set up design objectives, design constraints (limitation), and criteria (measure) for design evaluation for the following devices:

3. Self Driving Car by Google

4. Self Driving Car Potential market Customer Needs
People with limitation of visual capability (blind)
Daily commuters (people who travel a lot)
Customer Needs
Self driving automobile
Voice recognition
Satellite assisted to reach final destination
Maintain prescribed speed and distance with surrounding cars
Nearby cars detection to avoid accident
Setting for aggressive/conservative driving
Vehicle speed and acceleration optimization for fuel efficiency
Follow path of road safely
Satellite communication to avoid traffic jam, construction or accidents
Routing to gas station when fuel is needed
Hotel and restaurant destination choices
Estimated time of arrival display
Warning system for inappropriate/dangerous operation

5. Design objectives Criteria Constraints Primary objective:
Design an self driving car that assisted by satellite to reach final destination, with voice recognition, nearby cars detection, etc.
Secondary objective:
The car can calculate time for arrival to the destination , hotel and gas station, can give recommendation, etc.
Criteria
Safety, price, easy to use, less maintenance, features
Constraints
Cost not exceed: SAR
Minimum capacity of passengers: Nos.
Maximum speed: km/h

6. Design evolutions for the following device;
Self-driving car
Cellphone charger powered by kinetic energy
Automatic floor cleaning
Futuristic smart car

7. Preview; Case No. 2 Cellphone charger powered by kinetic energy
Convert kinetic energy to electricity. It can be drawn from activities like jogging, walking, driving, dancing and cycling.

8. The device can be strapped around your shoes as well
The device can be strapped around your shoes as well. As you go out to practice and play, it generates charge which can be sent to a device via USB cable.
