Creating a Model for Developing and Evaluating Technical Instructions that use Extended Reality

Purpose: Extended reality (XR) is an umbrella term for the many ways that we can now design 3D, interactive, and real-time environments as in combining virtual and real elements, and experience immersion in a completely virtual reality (VR). The use of XR is increasing in popularity across a range of industries. Although researchers are becoming increasingly interested in the benefits and challenges of using XR to convey technical instructions, more comprehensive research is required. I aim to address this need in the present article by introducing an affordance model of Technical Instructions in Extended Reality, the TIER model. Two earlier categorizations, the affordances of technical instructions, and the phases of data handling in XR, formed the point of departure for this article. The analysis utilized a four-category model of affordances by Rantakokko and Nuopponen (2019) that comprised: accessing, finding, understanding, and relying on. Data handling in XR drew on a phase-based model by Rantakokko (2022) featuring: collection, processing, storage, transfer, combining, and presentation. Methods:The two sets of categorizations were combined into a holistic model with an iterative process in order to offer a tool for analyzing and describing the possibilities and challenges that XR brings to designing technical instructions. The iterative process was conducted by adding examples from existing research into matrix tables to understand how the affordances of technical instructions and the phases of data handling in XR are connected. Results: The TIER model is introduced with examples to illustrate how it can be used to view every phase of XR data handling in terms of the affordances of technical instructions based on the laws, regulations, principles of good guidance, and the design process. Conclusion: The TIER model can be used as a tool for an organized, step-by-step design process as well as testing XR-based technical instructions to ensure that the features of XR support the intended affordances of technical instructions. technical instructions, affordances, extended reality, mixed reality,
