Augmented Reality and Cognitive Load

Extract

[...] Augmented reality influences several characteristics of the user. It influences problem-solving ability, the ability to retain information, and learning, emotional self-regulation capacity. The NASA-TLX, which is a subjective and multidimensional assessment tool, was used in this study to understand this influence. It has been shown that its use can actually reflect interesting and meaningful cognitive processes. At least 5 sources of variation are cited: variations in the objective and subjective importance of different characteristics in relation to the workload of different tasks, experimental variations in the magnitude of different factors, differences in the rules according to which individuals combine information about the task, their own behavior and psychological responses to the task in subjective experiences of workload, difficulties associated with translating a subjective experience into a manifest evaluation, lack of sensitivity to experimental manipulations7.

[...] The theory of cognitive load is not a 'theory of everything'. It is not intended to be applied to non-educational contexts. In certain domains that focus more on skill development, theoretical explanations may not be useful for explaining how these skills are developed Augmented reality has garnered a lot of attention in educational research because it is associated with many expectations of more motivating and more effective learning In the field of education, it is predicted that the integration of AR will help to develop learning and this will give more effective results.

[...] Poorly constructed materials and cluttered classroom environments can lead to a split-attention effect and add to unnecessary cognitive load. It is our duty to reduce this in the way we present our lessons. In simple terms, the split-attention effect is the distraction generated by using too many conflicting principles. This hurts cognitive load. Unnecessary or germane load is what we actually want to happen, it is the ability of working memory to link new ideas with information in long-term memory. The more prior knowledge a student has, the more efficient the relevant loading step is. [...]

[...] It has been shown that augmented reality-based information technology systems (ITS) improve retention knowledge by up to 25% among novices, and experts benefit more from an RA-based training system without ITS. In addition, the details of the RA and the number of remediation steps should be reduced as expertise increases. Novices evolve along a changing process to become experts. Therefore, as novices quickly become experts, RA and ITS are then required to adapt to the evolution of expertise. Without these considerations, a novice effect in RA and a conditioning effect in RA are likely to occur, diminishing problem-solving performance and potentially interfering with learning8. [...]

[...] In what ways does augmented reality influence cognitive load? There are three types of augmented reality, immersive, augmented and mixed (AR and MR respectively). In science fiction, traveling through time, being teleported to the past and also the future has always inspired and dreamed the human being. This is now possible thanks to the technology of augmented reality. This technology is taking on more and more scope with the condition that smartphones and other RA compatible devices will be more accessible around the world. [...]
