Abstract : A review of sampling processes and forms of continuous signal reconstruction therefrom has revealed several forms which may be useful in modeling the average display scanning behavior of the human operator. The most promising form appears to be cardinal reconstruction. Low frequency approximations to the effective time delay for truncated cardinal reconstruction are only slightly less than for linear reconstruction. The influence of sampled first derivative and of sampled dwell time appear analogous to the influence of sampled prediction in reducing the effective reconstruction time delay. The implications of these results for the measurement and interpretation of multi-instrument display tracking are discussed. (Author)
