PEOPLE INTERVIEWED “She forgets to turn off the tap, and

leaves the water running, lights too..” –Caretaker

“I think old people have trouble reaching for switches in the dark.” – Working adult

“I am concerned about her falling down, I have to watch her constantly..” - Caretaker

POSSIBLE SOLUTION

To reduce the consequences caused by forgetfulness:

Motion Sensing switch

Existing product found

Product Reviews:

•Light turns off too quickly

•Insufficient current supply to certain lights

•Difficult to install

Solution strategy:

Split

Device 1Stick-on battery operated transmitter that senses presence of the elderly,

sends to receiver

Split

Device 2Stick-on device that gets

transmitter signal and physically turns on/off light

switch

Transmits to

Solves the problems

• Light turns off too quickly

• Insufficient current supply to certain lights

•Difficult to install

Able to stick-on to any surface, close to spaces frequented by elderly

Uses existing light switches, rather than

relaysConvenient peel and stick using adhesive

pads

Testing selected solution

1)Create physical paper prototype

2)Interviews, collect feedback

3)Re-iterate design using feedback

Identified a target market:25% surveyed use sensors at home

76.7% surveyed would use the device

Three out of five interviewed would purchase the device

Mention of the elderly led to agreement on the usefulness of the product

Conclusion

INTERVIEWS

“This would be very useful for my children, they are not tall enough to reach the switches..” -Mother of two

“I would get this for all the appliances in my house..”– Working adult

Prototyping in progress

• Sketches of mechanism

• Paper Prototypes
