[1] Fitts's law is used to model the act of pointing , either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor ...

The "optimal viewing distance" [5] is based on the limits of the human eye, i.e. its angle of resolution. This is its ability to distinguish between two pixels. For normal visual acuity (6/6 vision), this angle is 1 arcmin. To obtain a fixed distance for a given resolution, it must be expressed in picture heights (H). [5]
