Aplaudes when you put the dirty dishes in the dishwasher, Calls you up and thanks you when you put the socks in the hamper and the wet but clean laundry in the dryer. It also tracks how the household is doing as a team, and congratulates you when you join the effort.
Actually, I thought at first
about a PutMeBack device that nags you to put the used cup in the dishwasher (it feels the change in temperature and so knows when it has been left out) and the same for your car keys when you get home, and for the cold water bottle that needs to be filled and left in the fridge. But then I started thinking positively and constructively.
There used to be a "standing ovation" website which did a good job at uplifting your spirit and making you laugh even though it was corny. Nowadays, a device that is paired to an app is probably easy to make.
In any case, it's easy to make the mobile phone whimper a bit when it's going out of power and clap its hands when you finally plug it in. When you tell it "good night" it should say: wait, could you please plug me in. and then give you a nice: Awwww that feels so good.
== Not directly related to the idea's description: =====
Here's an interesting thing I just noticed: Ovation is from Latin Ovare meaning exultation which stems from the Greek Ovo which is an onomatopoeic word that originally was spoken as Oh Woe!
In Ancient Hebrew there is a Psalm in the bible Havoo Li<Y.H.F.H God's name> Bney Elim, meaning sons of gods praise (the name of God) Havoo La... meaning Give to...
This psalm's parallels were found in the Israelite army site and temple in Egypt on the island of Jeb in the Nile. It was written in the Aramaic language and Egyptian Demotic (priestly short type of cuneiform) writing system mentioning the northern Israeli gods such as El Bethel and Baal Shamin and is possibly of Syrian origin.
The reason I'm mentioning this is that possibly it was read as Hovoo rather than Havoo, not meaning "give" but "exalt", which would be more befitting the general meaning of the text.
