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.

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

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

Sensors
Sensor – a device that takes a readingExamples:– Thermometer (temperature sensor)– Light sensor– Clock (time sensor)– Tiltometer (3D orientation sensor)– Motion detector
![Page 8: Testing the Usability of the SEEU System Seth Holloway, PhD Candidate Christine Julien, PhD The University of Texas at Austin IRB#2010-02-0052](https://reader036.vdocuments.us/reader036/viewer/2022062720/56649f125503460f94c24f2e/html5/thumbnails/8.jpg)
Actuators
Actuator – a device that performs a commandExamples:– Thermostat– Lights– Fan– Blinds– Alarm
![Page 9: Testing the Usability of the SEEU System Seth Holloway, PhD Candidate Christine Julien, PhD The University of Texas at Austin IRB#2010-02-0052](https://reader036.vdocuments.us/reader036/viewer/2022062720/56649f125503460f94c24f2e/html5/thumbnails/9.jpg)
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

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

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

Task 1a
• Edit an existing sensor • For example, change the name or description
![Page 14: Testing the Usability of the SEEU System Seth Holloway, PhD Candidate Christine Julien, PhD The University of Texas at Austin IRB#2010-02-0052](https://reader036.vdocuments.us/reader036/viewer/2022062720/56649f125503460f94c24f2e/html5/thumbnails/14.jpg)
