The technology and engineering issues include the creation of accurate, wearable, rugged sensors and wearable input/output solutions, the development of machine learning and pattern recognition techniques for generating insights from the data, the creation of tracking and rendering algorithms for augmented and virtual reality systems and software platforms to deploy them. The Human-computer interaction issues include the need for user-centered design processes across a wide-array of stakeholders as well as lab and field-based evaluations of the resulting technology interventions/experiences. There is also a need to leverage expertise in biomechanics, bio-informatics, physiology, neuro-science to create safe, effective, scientifically validated solutions. Similarly, there is a need to inform the projects based on human-factors psychology and cognitive theories around training and feedback.  The industrial design issues include the need to fabricate aesthetically appropriate, wearable, socially acceptable physical devices to be placed on the body and installed in the physical environment along with compelling digital media experiences.
