- Companies in various fields are developing information systems that are supposed to show information in a context sensitive manner. This involves modifying user interfaces based on the current activity and location of the user. The research that exists for context aware, task aware, and location aware systems come mostly from research in the office environment and using stationary work computers using standard mouse and keyboard-operated systems. Other environments, such as manufacturing environments, have not received the same research attention, and therefore research is required to see whether existing theories and frameworks apply to the manufacturing domain. Adding to this, context aware systems are now being created for new classes of devices such as mobile and wearable devices, to be used in multiple domains. All this requires an investigation and validation of older research, and shows how the research of the basic human factors surrounding new devices and domains has fallen behind the development of the devices themselves. This paper examines shortly how recent changes advances in technology affect what is required from the field of interruption research, as well as what is needed to support other domains than the office environment.

- The interest in cognitive aspects of human performance has dramatically increased in recent years in manufacturing, complementing the area of physical ergonomics, and the expanded focus on cognitive aspects may offer significant insights and contributions to industrial domains. A considerably increased interest has been directed at the role and effects cognitive load has on human performance, and ultimately on production outcome. The main question addressed is: How can an understanding of cognitive load in manufacturing lead us to design better workplaces for the personnel at the shop floor? To answer this question, we have to consider how technology interacts with work environment and with human cognition from a systems perspective. Technology should be considered a resource in the design of a better working environment, aid those activities for which we are poorly suited cognitively, and enhance those cognitive skills for which we are ideally suited. This has resulted in a potential framework of factors that might have impact on high cognitive load, consisting of three levels; internal factors, external factors, and activity space. The initial framework focuses primarily on the former factors, identifying risks where a high cognitive load might lead to difficulty of work, negatively affecting production outcome.

- Interest in cognitive or mental workload has over the last couple of years increased drastically from a manufacturing application perspective. More and more, people are becoming aware of the cognitive limitations that may have great impact on production outcome. The more easily observable area of physical ergonomics has been successfully investigated for a long time and it would seem as though focus has broadened to also include cognitive ergonomics. Considering the effects that a large cognitive load has on human performance, knowledge regarding the role of the cognizing human in a manufacturing environment could potentially have significant effect on production outcome (i.e. quality and productivity). With this in mind, developing and using methods and tools for assessment of the cognitive burden associated with particular tasks or workstations should be and is of substantial interest to the manufacturing industry. Whatever assessment methods exist in the scientific literature today are almost exclusively expert tools where significant expertise in the area of cognitive ergonomics/psychology/science is required. This paper reports parts of the development process and initial version of a non-expert tool for assessment of cognitive load in manual production environments, primarily manual assembly.
