Emerging Technologies Tetrad

At the time of this publication we have not yet developed the ability to create an augmented reality like the ones depicted in science fiction. The holodeck of Star Trek Next Generation’s Enterprise is still considerably far off in the distance. However, augmented reality is currently considered by many to be an emerging technology. One way to examine the impact of a technology as it emerges is to use McLuhan’s tetrad (Thornburg, 2013). To further understand the nature of augmented reality emerging into our society we will ask questions centered on each area of the tetrad.

1. Extension or enhancement – How will augmented reality extend or enhance the natural abilities or functions of the user? Augmented reality increases the connection between the real world and the digital world. “The result is a more effective demonstration of spatial and temporal concepts, as well as of the contextual relationships among real and virtual objects” (Billinghurst & Duenser, 2012 p. 56). Interacting with three dimensional objects in a three dimensional work space is simply more natural.
2. Obsolescence – What technologies or process could become obsolete as augmented reality grows in popularity? As this technology grows and continues to demonstrate its effectiveness as an educational tool using two dimensional modeling could become a thing of the past. Imagine using augmented reality to enter a virtual world where you can easily experiment with various engineering and design principles. This type of learning environment is one where computer screens and paper become a thing of the past.
3. Retrieval – The augmented reality can be seen as a revival or return to hands on learning activities. Often these are major features in early learning but seem to dwindle as the materials needed become more complex. Through augmented reality the size or complexity of the objects being manipulated is simply a matter of programing and design. This lowers the cost and even the space needed to a more reasonable level.
4. Reversal – What factors or developments could trigger a reversal of augmented reality? One possible catalyst that could trigger the reversal of augmented reality is 3D printing. If the cost of 3D printing continues to drop as the possible size of items created then it is possible that some aspects of augmented reality could be replaced with actual reality.
