Spatial computing evaluation framework. A holistic approach to evaluate the user experience in mixed/augmented reality

Abstract

Spatial computing is an emerging technology which combines the physical and digital space and enables interaction with spatial meaning. The extension of reality through virtual worlds creates new opportunities, but also uncertainties regarding UX and UX evaluation. This is reflected in the current state of the art, where human factors in spatial computing tend to be overlooked and the focus is often on technical considerations. Consequently, there is a lack of knowledge in HCI about which aspects should be considered in the UX and evaluation of spatial computing applications. However, contextual factors such as the emotions of a place, the surrounding community, and the activities in the augmented space are crucial as the user experience in spatial computing is fundamentally shaped by context.

To support researchers and experts in HCI, the Spatial Computing Evaluation Framework has been developed. It provides support and guidance for the UX evaluation of spatial computing applications, without limiting exploration. The framework aims to evaluate the situation holistically, highlighting the connection between the physical, digital and social context.

The framework was developed through an extensive literature review followed by a user study using the Apple Vision Pro. In order to emphasize the interconnectedness of the physical, digital and social environments in spatial computing, the theory of 4E cognition was used to build the framework. The specific guidance the framework provides is a novel contribution and can be particularly supportive in the early stages of the field to rapidly build up knowledge and create awareness.
