A NOVEL EXPERIMENTAL DESIGN OF A REAL-TIME VR TRACKING DEVICE

Virtual Reality (VR) is progressively adopted at different stages of design and product development. Consequently, evolving interaction requirements in engineering design and development for VR are essential for technology adoption. One of these requirements is real-time positional tracking. This paper aims to present an experimental design of a new real-time positional tracking device (tracker), that is more compact than the existing solution, while addressing factors such as wearability and connectivity. We compare the simulation of the proposed device and the existing solution, discuss the results, and the limitations. The new experimental shape of the device is tailored towards research, allowing the engineering designer to take advantage of a new tracker alternative in new ways, and opens the door to new VR applications in research and product development.

Axioms of Value

Extensive work exists on value in multiple domains. However, there are different interpretations, highlighting a lack of clarity about the fundamental characteristics. To address this, we present seven value axioms resulting from inductive research. The axioms may be viewed as general rules describing value in any context, therefore conveying the fundamental characteristics of the phenomenon. They reveal that value is: (1) connected to people; (2) an output of a cognitive process; (3) in requirement of a determination process; (4) a matter of a given situation; (5) determined by the interpretations of entities; and related to (6) entities and (7) criteria. The nature of value is of particular importance to the design community, given the emphasis on value in design and product development. In this context, a lack of clarity may be perceived in terms of when value appears, appropriate metrics, and how to add value. To provide explanations, there is a need for a theory of value in design. The presented axioms may provide the basis, as they are fundamental statements on the nature of value and not limited to a specific domain. We highlight theory requirements based on the axioms.
