1. Testing the Usability of Paper Prototype Interfaces Christine Julien, PhD and Seth Holloway, PhD Candidate The University of Texas at Austin IRB#2010-02-0052

2. Materials Present In front of you, you should see several items: – Cover letter – Consent form – Post-test questionnaire – Three paper prototype interfaces

3. Consent Form Please read and sign the consent form now. If you do not wish to complete, you may leave.

4. Pervasive Computing: A Brief Introduction The third age of computing has been termed pervasive computing – Characterized by many computers per person – Can be seen in practice with personal computers and cellular phones – More sensors and actuators will be available soon – Currently, there is no standard for programming pervasive computing applications

5. Sensors Sensor – a device that takes a reading Examples: – Thermometer (temperature sensor) – Light sensor – Clock (time sensor) – Tiltometer (3D orientation sensor) – Motion detector

6. Actuators Actuator – a device that performs an action Examples: – Thermostat – Lights – Fan – Blinds – Alarm

7. This Study We are learning how people specify behaviors in intelligent environments You will interact with three paper prototype interfaces

8. Interfaces Using paper prototype interfaces, we will be creating “policies” to govern the actions of devices in smart homes.

9. Available Devices In these examples, imagine you are controlling devices in a bedroom. You have data from a temperature sensor, light sensor, motion detector (presence sensor), and the current time. You can control the fan, automated blinds, lights, thermostat, and send SMS (text messages), email, or sound an alarm.

10. Interfaces You will be creating rules to govern behavior in a smart home using three interfaces Puzzle Mad-libs Magnetic poetry

11. Task 1a Create a rule to control the temperature in your bedroom using the Puzzle interface

12. Task 1b Create a rule to control the temperature in your bedroom using the Mad-libs interface

13. Task 1c Create a rule to control the temperature in your bedroom using the Magnetic Poetry interface

14. Task 2 Now, we will create a different rule—anything you please—using the available interfaces.

15. Task 2a Create any rule you please using the Puzzle interface

16. Task 2b Create any rule you please using the Mad-libs interface

17. Task 2c Create any rule you please using the Magnetic Poetry interface

18. Tasks complete! Please complete the post-test questionnaire

19. Thank you Have a great day!
