Testing the Usability of the SEEU System

1. Testing the Usability of the SEEU System Seth Holloway, PhD Candidate Christine Julien, PhD 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 • A laptop computer • Six Sun SPOT devices

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

4. This Study • We are learning how people use a prototype aware home system, SEEU • SEEU - Sensor Enablement for End-Users • You will be creating “policies” to govern the actions of devices in smart homes. • As you proceed through these tasks, it may be helpful to imagine that you are interacting with your own smart home.

5. A Brief Introduction • Computing began with mainframes, then personal computing • We are now in the third age of computing, pervasive computing • Characterized by many computers per person • Can be seen in practice with laptop and tablet computers, cellular phones, etc • More sensors and actuators will be available soon • Currently, there is no standard for creating pervasive computing applications

6. Smart Homes • Smart homes are a very promising pervasive computing application • Computers embedded in the environment can automate common tasks to provide improved convenience, comfort, energy efficiency and security • Home automation for the elderly/disabled can provide increased quality of life for persons who otherwise require caregivers

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

8. Actuators Actuator – a device that performs a command Examples: • Thermostat • Lights • Fan • Blinds • Alarm

9. Rules Rule – a mapping between sensor readings and actuator commands Example: • If it is dark, turn on the lights • If the light sensor reading is low, change light command to on

10. Disclaimer If you have questions, ask. This is not a test of your abilities. Your participation is greatly appreciated! NOTE: Web page values will not update automatically—you will need to refresh the page (command+r or icon on the address bar)

11. Available Devices In these examples, imagine you are controlling devices in your home. • You have data from a • temperature sensor, • light sensor, and • tiltometer (think of it as the angle of your front door) • You can control the • fan, • alarm, and • air conditioner

12. Smart Home System You will be exercising the functionality of a smart home with three basic actions • Edit • Delete • Create Performed on sensors, sensor readings, actuators, actuator commands, and rules.

13. Task 1a • Edit an existing sensor • For example, change the name or description

14. Task 1b • Edit an existing actuator • For example, change the name or description

15. Task 2a • Create a new sensor • For example, a sensor that reports presence (think motion detector)

16. Task 2b • Create a new actuator • For example, automated window blinds that can be remotely raised and lowered

17. Task 3a • Create a new sensor reading

18. Task 3b • Edit an actuator command

19. Task 4 • Manipulate sensor inputs to trigger a rule • Or describe why a rule was already triggered

20. Task 5 • Delete and recreate a rule

21. Task 6a • Create a new rule from scratch

22. Task 6b • Manipulate sensor inputs to trigger your newly created rule

23. Tasks complete! • Please complete the post-test questionnairehttp://localhost:3000/feedback

24. Thank you • Have a great day!
