comment Fitts' law and minimum target size
@JørnE.Angeltveit Very interesting post. I think i get your reservations and agree if you are working on a specific application. However, i'm trying to get a way of estimating an at least ok/usable element size for varying modalities and applications. There are several publications that show how Fitts' law is able to predict the outcome of user studies that compare different input devices, so even if it is not the perfect way it should be valid to get an estimate ?

comment Fitts' law and minimum target size
I'm really looking for a generic solution so guidelines for a specific modality or even task/application environment are not what i'm looking for. I would however be interested how people came up with those guidelines as they should have done exactly the calculation i'm looking for using their application and modality parameters.

@André a and b are to be determined empirically since they depend on your input modality but T/D/W are really the things you are trying to determine as i understand it.

@JørnE.Angeltveit I think the idea of the law is that it will work for real users otherwise it would be pointless
