  6. 6. 2011 - NATURAL USER INTERFACE The ability to draw upon the investments in skill we make to undertake the activities of our everyday living experience, as a means to define methods for input modality has many advantages.  This is true for all user demographics.  Immediate familiarity with methods for interfacing, intuitively gifting users of the system with capability for basic interaction. Buxton (2010) describes such interfaces as “natural” detailing that an interface is natural if it “exploits skills that we have acquired through a lifetime of living in the world.” Blake (2010) furthers this definition by determining that an interface is natural if it is designed to utilise human behaviour for interacting directly with content.

  9. 9. TECHNOLOGIES THAT ENCALM In Designing Calm Technology , Weiser and John Seely Brown (1996) provide warning that whilst technological infusion has the great potential to improve and enhance our life experience, it also has the potential to impede and restrict it.  Hmmm…. 00001000001011001010010100010010010000011 In order to address this issue they describe the ethos of technologies that “encalm” as a manifesto for our future relationships with technology.  Must have bought a Betamax back in 80‟s?

  11. 11. WHY DESIGN FOR THE PERIPHERY? By placing technologies within the periphery we are able to become attuned to them, allowing them to be selectively and subconsciously called upon to inform detail. This in turn af fords us with an increased ability to attune to multisensory detail and thus, a greater level of knowledge to inform both response and our perceived locatedness”.
  12. 12. INFUSION OF NUI & DFP From the infusion of the concept of designing for the periphery, with that of the Natural User Interface we can derive a powerful and innovative means for the application and development of interfaces. Interfaces of which from the outset we are familiar, but that also af ford us with an enormous volume of detail.
  13. 13. PERIPHERY MAPPING “As a PE the cane enables a user with an enhanced perception of their environment in many ways. The most immediate and obvious being indication of future potential of obstacles and hazards that may appear within our environment, however when viewed in terms of the peripher y the cane also provides an operator with much more detail than this . Movement across the ground affords additional information such as texture via subtle nuances in vibration; this is fur ther enhanced via the sound transition across par ticular materials. Over time a DT naturally develops a database of such peripheral cues allowing for the identification of the construct of their environment as a visual non impaired user we do the same by also collecting cues from the peripher y .”
  14. 14. PERIPHERY MAPPING “At the same time both auditor y and touch senses provide cues that indicate it is raining, this is fur thered by the subtle reduction in friction the cane makes as it is moved across the surface of travel, in conjunction sound subtly dampened whilst also complimented by the swish made by the movement that experience indicates to be water.” “A slight change in balance indicates the possibility of an incline, however the canes balance in the hand during a concurrent sweep remains similar, a lack of additional pressure on both the fingers and palm indicates resulting and suggesting that in fact we are just on a bump in the road, differing volumes of pressure on the ball, arch and heel of the foot clarify this fact. This is fur thered by our innate proprioceptive functions that tell us our foot in fact parallel to the other just slightly rose in height.”
