Developing the Spatial Computing Evaluation Framework: A Holistic Approach to Evaluate the User Experience in Mixed and Augmented Reality

The rapid technological advancements in Location-based Services, Augmented and Mixed Reality, Wearable Computing, and Sensor technologies paved the way for the new paradigm known as Spatial Computing. To date, little work has focused on user experience (UX) design and evaluation for Spatial Computing applications despite the emergent need for guidance and references for UX researchers and designers. We aim to address this gap by proposing the Spatial Computing Evaluation Framework based on a literature review and an initial empirical user study. Grounded in 4E Cognition theory, we unpack its Embodied, Enacted, Embedded, and Extended dimensions relevant to UX in Spatial Computing, emphasizing the interconnectedness of the digital, physical, and social environment. The framework can be seen as a valuable instrument for UX design and evaluation of Spatial Computing applications.
