Chapter 5: Non-manual control task selection

This chapter gives a detailed statement of the necessary features of a task that could be studied in the manner envisaged here. This would be useful for anyone considering undertaking a similar study. It goes on to evaluate options available at the time of the study, concluding that no available systems were suitable, and that a new task had to be constructed specially.

Chapter overview and links to contents

The problems of the last chapter led to the recognition that the study must proceed with the study of a non-manual task. At this point, there was enough clarity to formulate the requirements of such a task, and to make a rational choice. The first section is the rationale behind the selection criteria.

5.1 Criteria of suitability for study
5.1.1 The level of complexity of the target system and task
5.1.2 Level of control
5.1.3 Independence from psycho-motor limits
5.1.4 Realism, task definition and feedback
5.1.5 Adaptability of the task and the interface
5.1.6 Logging
5.1.7 Obtainability

The second section starts with a table of comparison, going on to explain the table, and to use it in selection.

5.2 Choice of experimental system
Table 5.1: Comparing experimental options against criteria
5.2.1 A nautical simulator
5.2.2 STEAMER
5.2.3 A toy flight simulator
5.2.4 Other existing computer games
5.2.5 A nuclear power plant simulation
5.2.6 Another nautical task simulation
5.2.7 Decision, and implementation implications
