Core Themes for the Workshop
•How Smart Homes Are Portrayed
•What Are Smart Homes?
•Why Smart Homes and Community Care?
•Types of Smart Home Technology
•Appropriate Design
•Where to get Help
PART 1
The most common features of a smart home
Environmental Controls
Enable a person to control
•Lights
•Heating
•Ventilation
Security Systems
Enable a Person to:
•Feel secure in their property
•Detect motion in the house
•Protect the vulnerable person
Enabling Systems
Enable the Person to:
•Undertake common tasks that they find difficult
•Undertake tasks they would not be able to do
•Undertake augmentative caring roles
How are smart homes portrayed
Enabling the enabled?
The Plaything of the Rich
Or as a Geeky / ‘macho’ thing full of computers and technical
stuff
The Main Purpose of Smart Home Technology
What are Smart Homes?
Smart Home Technology means:
Devices are able to carry and store the information and ‘know’ what they are
and what they are supposed to be doing
What are Smart Homes?
Smart Home Technology also means:
Devices are able to determine what all other
devices in the system are doing and supposed to be
doing
What are Smart Homes?
Smart Home Technology also means:
That computers are not always required to enable
the devices to continue their activities.
Busline Technology
The EIB Busline
Disorientation on waking?Need for toilet at night?
Activates pressure pad at side of bed
Light illuminates gradually
Lights come on in hall and bathroom
User goes to bathroomLights can be switched off manually
And set to go out after a period
Devices don’t operate in isolation
Can incorporate many safety features
Pressure pad activated...
Alarm sent if not reactivatedTo call center, formal or informal carer The home is
connected to the outside world
Smart homes Summary• Enable people to undertake tasks
that they might be unable to do normally.
• Enable people to feel secure.• Control some of the main household
electrical features.• Provide a better quality of life to the
occupant of the house.• Empower the [email protected]
Smart homes Summary 2
•Can provide carers with additional support
•Enable caring levels to be increased as there can be more
one to one person contact
•DO NOT PROVIDE A SUBSTITUTE FOR STANDARD
CARE PACKAGES
Part 2
Some of the Most Commonly Used Smart
Home Devices
Automated Window Opener
An Infra-Red Receiver (IR)
A Passive Infra-Red Sensor - the ‘magic eye’ or motion detector (PIR)
An Automated
Curtain Motor
Touch Switches for minimal upper body mobility
EIB Switches
A Bus Coupler
This stores the information for the devices
The Switch Fascia fits into the Bus coupler and becomes a switch
Selection of Appropriate Switches
Alternative Switches
A Multiple Dial-up External
Communicator
Controllers
Direct Automation
Passive InfraRed Sensor Taps
Passive Infra-Red Bath Tap
Controls
PIR Taps enable limit upper body mobility to
control water supply
Door Entry Systems
Door Entry Systems 2
The Consumer Unit or Control
Boxes
Standard Switches
Interactivity and Automation
Control over the Domestic Environment
Part Three
Types of Smart Home Technology
There are generally three main types of technology:
•x10
•Radio Frequency (RF)
• Busline (EIB)
X10
Problems:
•One way protocol
•Unreliable
•Requires computer
Conclusion: NOT SUITABLE FOR PEOPLE WITH DISABILITIES
Radio Frequency (RF)
eg. Bluetooth and Powerline
Problems:
•Not fully tested
•Interference may effect operation
Conclusion: NOT SUITABLE FOR PEOPLE WITH DISABILITIES
Busline
•Two way protocol
•Robust and reliable
•tested extensively throughout Europe
Conclusion: MOST SUITABLE FOR PEOPLE WITH
DISABILITIES
Part Four
Some Thoughts on the Design Process
A quick quiz to get you thinking straight.....
Question Number 1How do you put a giraffe into a refrigerator?
The correct answer is: Open the refrigerator, put in the giraffe and close the door.
This question tests whether you tend to do simple things in an overly complicated way.
Question Number 2How do you put an elephant into a refrigerator?
Wrong Answer: Open the refrigerator, put in the elephant and close the refrigerator.
Correct Answer:Open the refrigerator, take out the giraffe, put in the elephant and close the door.
This tests your ability to think through the repercussions of your actions.
Question Number 3
The Lion King is hosting an animal conference. All the animals attend except one. Which animal does not attend?
Correct Answer:
The Elephant.
The Elephant is in the refrigerator.
Remember?
This tests your memory.
OK, even if you did not answer the first three questions correctly, you still have one more chance to show your abilities.
Question Number 4There is a river you must cross. But crocodiles inhabit it. How do you manage it?
Correct Answer: You swim across. Why? All the Crocodiles are attending the Animal Conference.
This tests whether you learn quickly from your mistakes.
Some GOLDEN Rules to Smart Home Design
Does the design meet the needs of the person(s)?
Is the most appropriate design used?
Would conventional technology not work better?
IS THIS REALLY THE BEST DESIGN?????
If the answer is YES to all.....
Well Done
Sounds like you are on a winner
Has the design been discussed with other stakeholders?
Are you within budget?
Have you remembered the hidden costs??
The Hidden costs of SMART Homes
•Installation- Retrofitting/new build
•Ordering devices- time=£
•Your time and travel costs
•Maintenance- The system will need maintenance
•Third party failures - late arrival of parts, job set backs etc
Smart home Technology cannot replace barrier free
design
Often Common problems can be sorted by good design
Not Technology led answers
