I'm sure I've seen this before, but I can't track it down.

I'm working on something that involves measuring the accuracy of clicks. IF I use the same virtual dimensions for all dimensions, the 10" tablet owners will have a very distinct advantage over the 4.5" mobile users.

Is there any data in AppGameKit (2) I can use to assess the physical size of the users' device?

I can get the base name and type, but this needs to be accompanied by a very large database of all device brands and sizes available.

Hm

you are right not all devices have the same "physical" size when they have the same resolution.

The problem is that tablet's wich are larger than an smartphone (physical size)but have the same resolution... the tablet owner does have an advantage because you can better aim on it... hm

We don't have access to the physical size of an device ...you can't even read it from the OS... and i don't know a Data base with all devices.

BUT maybe you can measure the devices size via input...
you could ask the user to put two fingers on the device and calc the distance from the multitouch events.
Then you can either assume that the normal distance is ~1 cm and calculate the device size... ( I have to go)

Nice idea, this could work for many applications.

But for me, with a global scoreboard, the tablet owners (who have the advantage) can cheat by placing their fingers further apart to "shrink" the perceived size of the screen.

I wonder how much advantage it gave to Flappy Bird players, or that flying Dragon game with the hills?
