围绕World first这一话题，我们整理了近期最值得关注的几个重要方面，帮助您快速了解事态全貌。
首先，Goodstein (1981) has discussed process displays which are compatible with different types of operator skill, using a classification of three levels of behaviour suggested by Rasmussen (1979), i.e. skill based, rule based and knowledge based. The use of different types of skill is partly a function of the operator's experience, though the types probably do not fall on a simple continuum. Chafin (198l) has discussed how interface design recommendations depend on whether the operator is naive, novice/competent, or expert. However, he was concerned with human access to computer data bases when not under time pressure. Human-machine interaction under time pressure raises special problems. The change between knowledge-based thinking and reflex reaction is not solely a function of practice, but also depends on the uncertainty of the environment, so that the same task elements may be done using different types of skill at different times. It could therefore confuse rather than help the operator to give them a display which is solely a function of their overall skill level. Non-time-stressed operators, if they find they have the wrong type of display, might themselves request a different level of information. This would add to the work load of someone making decisions which are paced by a dynamic system. Rouse (1981) has therefore suggested that the computer might identify which type of skill the operator is using, and change the displays (he does not say how this might be done). We do not know how confused operators would be by display changes which were not under their own control. Ephraph and Young (1981) have commented that it takes time for an operator to shift between activity modes, e.g. from monitoring to controlling, even when these are under the person's control, and one assumes that the same problems would arise with changes in display mode. Certainly a great deal of care would be needed to make sure that the different displays were compatible. Rasmussen and Lind's recent paper (1981) was about the different levels of abstraction at which the operator might be thinking about the process, which would define the knowledge base to be displayed. Again, although operators evidently do think at different levels of complexity and abstraction at different times, it is not clear that they would be able to use, or choose, many different displays under time stress.
