Abstract
Goal items were selected by a series of touch-menu choices among sequentially subdivided ranges of integers or alphabetically ordered words. The number of alternatives at each step, b , was varied, and, inversely, the size of the target area for the touch. Mean response time for each screen was well described by T = k + c log b , in agreement with the Hick-Hyman and Fitts' laws for decision and movement components in series. It is shown that this function favors breadth over depth in menus, whereas others might not. Speculations are offered as to when various functions could be expected.

The experiments reported in the present paper extend the theory to the human motor system, including the visual and proprioceptive feedback loops that permit S to monitor his own activity and create an experimental situation in which it is reasonable to assume that performance is limited primarily by the capacity of the motor system.

It is conceivable that such judgements are made in the same way as judgements of stimuli varying along physical continua, but numerical judgements may be made at a different, less perceptual and more cognitive, level.

In the typical reaction-time experiment, S's reaction time is greater when he has to respond differentially to one of two equally probable stimuli instead of to just one stimulus, but this becomes even more significant when looked at from the standpoint of modern communication theory.

This chapter discusses the abstraction and the process of recognition, concerned with the successive stages of processing that are involved in the encoding of simple stimuli and with the record that each stage produces.

Goal acquisition speed and accuracy were compared for subjects using four different menu configurations of a semantic hierarchy on an interactive computer terminal demonstrating that the fastest conditions also produced the least errors.

The results suggest minimizing the depth of tree structures by providing menus of eight or nine selections each, which is consistent with known limits on human information processing capacity.
User perceptual mechanisms in the search of computer command menus

Menu-based command systems, in which a user selects a command from a set of choices displayed to him, have acquired widespread use as a human-computer interface technique.

In the present study, subjects searched through one of four verbal hierarchies developed by Miller (1981), each with 64 words at the lowest level, and found the deepest hierarchy consisted of binary choices at six levels while in the broadest array all target words were presented in a single menu.

Two experimental comparative studies of two prominent data models; the relational and hierarchical models were presented and significant effects were found for the data model, presentation order, subject background and tasks.

This research compares several different ways of describing ill-defined categories of objects using combinations of names and examples to provide a promising possibility, both as a means of flexibly naming new or difficult menu categories and as a methodological tool for studying certain categorization problems.
