Human factors guidelines for terminal interface design
This paper provides a set of guidelines for the design of software interfaces for video terminals. It describes how to optimize screen layouts, interactive data entry,…
Natural command names and initial learning: a study of text-editing terms
In the first of two studies of “naturalness” in command names, computer-naive typists composed instructions to “someone else” for correcting a…
A hierarchical data structure for multidimensional digital images
A tree data structure for representing multidimensional digital binary images is described. The method is based on recursive subdivision of the d-dimensional space into…
The k-distribution of generalized feedback shift register pseudorandom numbers
A necessary and sufficient condition is established for the generalized feedback shift register (GFSR) sequence introduced by Lewis and Payne to be k-distributed. Based…
Precision averaging for real-time analysis
An analysis of the computation of the arithmetic mean using only single-precision fixed-point arithmetic is presented. This is done to ease the timing constraints common…
