My thoughts for this are that if advertisement company's can influence people to buy certain products, why cant I use that same technology to influence myself and my family.
A Burger King billboard might have a celebrity eating a hamburger, my digital signage could have mom or dad eating a apple. Software that checks the weather and puts a picture of a bicycle on a sunny day with the words " Its going to be a beautiful day today, why not use your bicycle to run that errand." Depending on the time of year the digital signage could pull recipes and put up pictures of recipes that have fruits or vegetables that are in season.
I install communications systems for Data Centers, Hospitals, Schools and Offices. Digital signage is a big thing right now. Aesthetically when done correctly it is beautiful and adds a nice touch. If installed at my home my wife would require it to look like a piece of artwork hung on the wall, and it could be.
Is this just a fancy toy or is it a useful tool that can influence our family's habits?
