I would guess realist.

this is for someone that loses the remote (keys, phone...), talking from experience, this either happens for one of three reasons
1)someone sometimes leaves with remote
2)remote is eaten by the seat
3)remote went flying somewhere

all of these can easily happen with this device.

let's call it a locator and the thing you are looking for the remote

step 1: click locator
step 2: walk with locator in hand to where the noise is coming from
step 3: find remote
step 4: pick up remote and leave down locator
step 5: wonder were you left the locator the next time you are looking for the remote :)
