Questionnaire 'shower'

Introduction:

We have created a device which helps you to become more aware of your showering behavior. In this way you get more inside in your water consumption. Please click on the button below to meet ‘Will’. He will give you feedback on your showering habits. Will: Hello I am Will! Thank you for joining. Let’s see how your typical shower goes.

Do you take a shower every day? (yes/no)

• Yes: (Sad) It is such a shame that you choose to behave in this way.

• No: (Happy) Yes, that is the way to go!

On the average, do you shower longer than ten minutes? (yes/no)

• Yes: (Sad) You let me down. Please change your behavior.

• No: (Happy) That is what I would like to hear!

Do you turn off the shower when you are using shampoo or soap? (yes/no)

• No: (Sad) I am disappointed that you waste so much water.

• Yes: (Happy) That is fantastic. Keep up the good work!

Do you own a rain shower?

• Yes: (Sad) It's a pity that you spill so much water by using such a shower.

• No: (Happy) Good! I'm glad you don't have such a shower.

Do you usually stay in the shower for a longer time than is actually needed?

• Yes: (Sad) Oh no, I think that's such a bad habit.

• No: (Happy) That's excellent! It's a really good habit.

Thank you for using our device! We will give you a short explanation of why Will commented in this way: It is not necessary for your hygiene to take a shower every day. It is actually bad for the condition of your skin as it dehydrates it. Besides that it is bad for the environment and for your wallet. Most of the time taking a ten minute shower is more than enough. There are exceptions of course for example when you need to shave yourself under the shower or when you are using a conditioner. Nevertheless we tend to stay under the shower longer than necessary. Mostly when it is cold outside and a warm shower feels too nice or when a shower is a nice way to wake up in the morning. Finally, keeping your shower running while you are using shampoo or soap is a massive waste of water. Most people even turn the showerhead sideways so it does not wash away the soap too soon. We cannot say it enough that it is bad for the environment and as well for your wallet.

Follow up questions 'shower'

We would like to implement Will in a smart home system where he can motivate you at home to think about and change your water consumption. Before we can do that, we need some feedback about how you experienced Will and how we can make him better. The following questions are about this experience.
