Topic Introduced: A three-dimensional interactive display system using hardware consisting of an array of linearly adjoining slices of concave mirrored surfaces This work is a proof-of-concept of the Control Unit (PIFCU) and the Interface Freespace (GCIF) which is the sensorized volume of space Translations of control through a visually bounded freespace Removes the need for keyboards and similar interface hardware Provides methods of construction, computer navigation, gaming, as well as a solution for certain physical limitations that traditional computing experiences currently exert on users (i.e. rigid hand angles for typing) 11/11/2013 Holly Ferguson 2013 IASTED Presentation 3
Research Background 1: Background in spatial architectural design Human-interactivity in computing is a personal interest Led to pursuing possibilities for computerized spaces Research began here addressing response to changes 11/11/2013 Holly Ferguson 2013 IASTED Presentation 4

Possible Future Uses and Conclusion Allows the creation of a type of holographic control unit Creates a 3D, human occupiable space, acting itself as an interface control system This approach provides freedom from the hardware (mouse, keyboard, etc.) The freedom from the hardware reduces ergonometric strain Setup allows future work to be improved for parallel computing (image side) Setup allows future work to be improved for parallel computing (screen rendering side) Setup allows future work to be improved for parallel computing (sensor field side) Will show both 2D and 3D applications of free-space API controls Could create a type of bridge between usage of current APIs This is not dependent on human/finger touch (i.e. could use a # of moving objects eventually) For later work, could become a layer acting on top of any OS Would have similar benefits to other holographic media The limits of certain parts of this system could act as beneficial in terms of security in the future In the future, could offer a new method to control an interface off-site via video feed This could build on the vast gaming application techniques Industry uses outside computing addressing security issues, hygienic issues, etc. Architectural Design Implications (personal & previous studies) Virtual reality spaces which are free of needing headgear(s) 11/11/2013 Holly Ferguson 2013 IASTED Presentation 14
