EDUC 7108-1 Emerging & Future Technologies

Invented by Roger Appledorn in the 1960s

Decline in sales and use beginning in the mid 1990s

Invented by Gene Dolgoff in 1984

Allows projection for large spaces and can connect to computers, document cameras, mobile devices, etc.

In your opinion, how does the overhead projector differ from the LCD projector?

If you had an overhead projector, how could it be used in your work?

If you had an LCD projector, how could it be used in your work?

Which of the two technologies would you prefer and why?

Why do you think we see fewer overhead projectors at this campus than we do LCD projectors?

Interview with Viltz.mp3

Overhead projectors were used less over time

As innovations were made, the need to create connectivity to technologies such as computers and document cameras became more ideal

Deleted the need for overhead projectors, allowed implementation of LCD projectors to emerge

Concept of overhead projector originated from the episcope

Was not used practically until the 1940s by the military

LCD projector was introduced while overhead projectors were still being used highly

Strong emergence occurred with introduction of sophisticated monitors

Other technologies less sophisticated technologies before the overhead projector, none emergence as strongly

LCD projector was less disruptive technology; expected with the emergence of the computer

Concept of overhead projector began in the early 1900s with the episcope

Overhead projector emerged during the 1940s and later was used in conjunction with the computer

LCD projector was created with the evolution of the liquid crystal display and the need for a smaller device

Both overhead projectors and LCD projectors were being used in the early to mid 1990s

LCD projector surpassed the overhead projector as a more suitable companion to the computer

Both types of technology were at the forefront for projection needs

Overhead projector was not able to step ahead of LCD projector (older technology)

Red.mp3

Popularity is beginning to wane during 2000s

New technologies such as Digital Light Processing (DLP), plasma and Liquid Crystal on Silicon (LCOS) are emerging

Expect to be obsolete within the next 10 years

Future.mp3

Both technologies provide projection services and can be used within K-12 education.

As technology has progressed, the LCD projector has moved to the forefront as the more efficient technology.

Within the future, this technology, like others before it, will become obsolete as another form emerges with the times.
