The operation of the electricity sector has resulted in more sophisticated equipment and requires more attention from operators. This results in increased cognitive load and environments more conducive to error, which can cause failures that result in significant economic losses, physical damage, or threats to human life. This research aims to evaluate the workload of the operators in two Elect...

For multi-modular nuclear power plants under the scheme of multiple steam supply system (NSSS) modules driving a single turbine, NSSS are coupled tightly with each other by common giving more complex normal operation respect to single-modular plants. To limit cost plants, one operator is assigned monitor and control two or modules, whose feasibility should be verified. Combined characteristics ...

INTRODUCTION: The visual scanning techniques used by helicopter pilots are a critical skill to accomplish safe and correct landing. According the human information processing theory, can be analyzed as function of fixation location, number, duration fixations. METHODS: This study assessed these in expert novice during an open sea flight simulation low-workload condition, consisting daylight goo...

In this pilot study, the authors employed a basic driving simulator to examine both driving behavior and task performance as subjects performed music retrieval tasks using one of three variants of the ”SpeakPod” voice search prototype. The variants shared speech and manual interface designs but differed in visual output capabilities. Preliminary data indicate that the chosen variant and the pre...
