WebThe effective target width (W e) column was added, as discussed shortly. Table 1 Data From Fitts' Tapping Experiment With 1-oz Stylus. Fitts conjectured that the MT-ID relationship is approximately linear, implying a constant rate of information processing. This is reasonably confirmed in the scatter plot and linear regression analysis in Figure 2. WebThe output or "effective" target width (W e ) is derived from the observed distribution of "hits", as described by Crossman and Welford (Welford, 1968, p. 147). This adjustment lies at the very heart of the information-theoretic metaphor — that movement amplitudes are analogous to "signals" and that end-point variability (viz., target width ...
