Describe what your interface does in 2 sentences or less.
My interface would keep track of valuables, alerting the user via a bracelet when any of the objects were too far away. It would also contain information to help track the objects down (serial numbers, online mapping service).
Who would use your interface?
Anyone with valuables that has to carry them around to different places, or anyone that loses their keys or has a dog they want to keep track of. The flexibility of the system means it can be used to track just about anything.
What would they hope to gain?
They would hope to not lose anything they had already gained, I suppose. Theft and misplacement prevention with real-time alerts.
What is the context/environment in which people will use your interface? Would it be used in public/private? Alone or in groups?
It would be used mostly in public, but only by one person (and whatever authorities were helping that person recover their goods).
What sorts of physical items might a user have to interact with?
A bracelet with a small LCD screen and a button or two, along with some various items that contain gps tracking systems: phone cases, laptop cases, ipad cases, small stickers, and keychain or pet collar tags.
What questions do you need answered about your interface to see if it is necessary or effective?
I need to know whether wearing a bracelet to be alerted of missing things is something people would be willing to do. Maybe if it looks more like a watch than a bracelet it would be more neutral. But I don’t want to add stress into people’s lives knowing you had this bracelet that might light up and vibrate if you leave your phone at home on purpose. So I’m still working out the kinks with the usability as far as turning the alerts on and off. I also want to be able to add in as many objects/tracker tags as the user wants into one bracelet, but I think the display interface is going to have to be really clear so that doesn’t get confusing.
