Tetrad for 3D Display

McLuhan's Tetrad for 3D displays

Enhances: What does this technology do that is new?

3D technology is not new it was developed in the late 1890’s by many different individuals:  William Friese-Greene, Etienne-Jules Marey and Louis Aime’ Augustin Le Prince. This new hardware began the stereoscopic era of motion pictures. However, this form of film was not widely excepted or produced because it was expensive to create. In this new era of 3D film IMAX lead the way, using 3D films as educational tools which allowed for mathematical correctness.

Obsoletes: What does this technology replace?

3D technology has the ability to replace 2D displays for television, computers, video games, and cinemas.

 Retrieves/Rekindles: What does this technology bring to mind (or retrieve) from the past?

This technology brings to mind the stereoscopic motion pictures and the equipment needed to create them. This brings to mind that 3D films previously were highly expensive to create and with the resurgence of 3D films that the cost may have come down.

Reverses: What might replace this technology in the future, or what might it cause to occur?

This technology may be replaced by virtual display. Televisions, computers, video games, and cinema may soon have virtual displays for audience to participate in the experiences of the entertainment.

Emerging Technology

From the raising of hands to the click of a button

For centuries students and participants responded to the teacher’s or presenter’s questions by raising their hand. Teachers would quiz their students utilizing multiple methods such as quizzes, tests, tickets out the door, or by having students respond to questions at the end of sections of the text. New technology has been developed to now provide teachers and students instant feedback; these devices are called student response devices. Teachers or presenters can provide students or participants with a question; each individual can respond to the question utilizing the method the method provided likert, multiple choice, numeric, sequential order, and others.

There are many companies that provide student response devices: SMART, Promethean, Qwizdom, H-itt, eInstruction, and many more. These companies provide these devices at varying price points. Some of these companies also provide professional development to help new users effectively utilize these new educational tools.

This technology also has research and articles to support its use with participants or students such as:
