On-screen augmentedrealitydisplays,coupledwithtactilefeedbackthroughthesteeringwheel andothervehiclesurfaces, could provide appropriatedisplay possibilities. Inputs to the system could include motion sensors, eye-tracking devices and physiological sensors to capture driver/passenger state, in addition to explicit controls such as tangible objects (switches, dials) and voice inputs. In addition to the range of functionalities listed above, traffic, vehicle and environmental data would form part of the ambient environment. Mechanisms for dynamic balancing would be needed to cater for emergencies and other changing circumstances, as well as for personal characteristics and preferences of specific users. Personal blended reality spaces could also interact with public spaces equipped with appropriate sensing and communication infrastructures. These would include ambient and other displays, sensing of participant locations and activities, amongst other features. Everyday events such as buying groceries, filling a car with fuel, or paying for parking space would simply require actions in physical space, and these would also enact intentions executed in the virtual realm – most importantly payment transactions – since aspects of the physical world will be dynamically identifiedwithinthecurrentblendedrealityspace.Therewouldbenoneedforcredit or other paymentcards, or mixedreality methods(such as sendinga specific mobile phonemessagestoparticularphonenumbers). In Conclusion Human-experiential design of physical-digital materials and environments has the potential to impact on our lives in several different but ultimately interrelated ways. Ourmental activities will be changed along with some of the ways in which we carry out our intentions. An integrated sense of mediated presence can potentially providea smootherlink between our intentions and actions in mixed reality. The way in which we perceive and function with our bodies – our sense of our own embodiment – will also be changed, when we perceive ourselves acting from the altered perspectives provided by technology.
