Interaction investigation

 

I have found this interaction design in my student accommodation and it is a electronic timer. Which does what you think it does!

 

Simply you just have turn the power on and the red lights will immediately be glowing. 

 

You can then press the BIG button to switch it on which will look like this....

 

This is what happen when you press that BIG button which shows you after 30 minutes your plug will switched off automatically.

When you hold the big button, you can now change the timer to 15minutes, 30minutes, 1hour & 2hours. 

Conclusion: 

What I like about this design is that it's simple to use, very useful for people who have bad memories and forget about turning off the electricity before going out/going to bed...etcetera. When you switch this off, this can save yourself some money and also saving the WORLD.
