so you never ever want to search for things again?
how cool would it be to have device that tells you what to put in your bag when you leave for work and even tells you where to look for said things. even reminds you to take this-fancy-new-gadget-to-be-shown-to-friends-in-the-pub. how does it know that you will not be back between work and the pub? you never go back thats why.
imagine a PDA like device, it knows when you have to be where, it has GPRS and GPS built into it and a RFID tag reader. With a little bit of training it will know what you take to work everyday and will notice that you always take your newest gadget to show it to your friends in the pub. it could monitor your mobile phone batts and tell you to take the charging device to the office as you will have to leave for the airport straight after.
How would it work? you enter your dates and todo lists as you do at the moment and also you attach a list of stuff to take to every "event". After a few days the software coudl start "guessing" these lists based on what you take to similiar "events". easy ones would be going to the gym or to office. slightly harder ones would involve a list of clothes et al to take on a 2 day trip to a customer.
Perhaps using RFID is not the best way to track your items. there is no way of knowing where the item realy is, the rfid reader can only tell if it is close enough so you would end up with a sphere in which the item has to be. easily improve it by telling the device the location of walls, track them while moving around and so deleting points in the sphere. just imagine yourself with a sphere of radius 2m around you moving around in a room. items would be visible from different places in the room but can only be in regions where all the spheres intersect or it has moved which would completly mess everything up. still knowing that an item is in this room is a great thign to know when trying to find something. so something as easy and cheap and small as a RFID tag which can be located from the reader woudl be ideal.
You probably do not want to do all this computing and database keeping on the PDA like thing, itll just use up batteries and stuff. this is where GPRS comes into play. use it to tell a "server" about the events entered and where you are and which items you can see. he will have enough cycles and no power problems to do all the maths for you.
A central server would also make it much harder to loose your database. It is much easier to backup a normal PC then makeing sure you do not loose your PDA or have it stolen.
