EDUC-7108 Emerging and Future

Technology

In the 1940s the first overhead projector were used by police for criminal profiles and

the U.S Army for military training. Roger Appledorn invented the modern overhead

projector in the 1960s. It was a flop until he reached out to businesses and teachers

across the country in order to increase the sales of the product and by the 1960s and

70s it was used by many businesses and classrooms.

The Elmo Projector is a document camera that displays objects and

documents that are not transparent. The Elmo digital camera display

more than just documents but can be used to display three-dimensional

objects.

The overhead projector was very important in the classroom for displaying information so that
all students could see at one time and it saved the teacher from having to write all this
information on the chalkboard. Also, the information could be stored for future use whereas if
it had been written on the chalk board it would have to erased and then rewritten if needed
later.

Yes. Teachers thought that it was an amazing technology because it saved them the time of
having to write or draw figures. Objects and other material on the chalkboard.

Some of the disadvantages of the overhead projector were that it could only display still
objects and transparencies . Also, as for its size, it was a large and bulky type of equipment
That took up a lot of space.

The Elmo can do a lot of things that the overhead could not such as display live and in color
objects that brings the presentation to life, display in 3D dimension, and can display different
types of documents that do not have to be transparent and textbook material.

The Elmo projector makes the overhead projector, slide projector and opaque projector
obsolete.

The Elmo projector rekindles the Overhead projector, chalk board, and blackboard
from the past.

The Elmo projector represents an increase in students learning and achievement. It is
a technology that is valuable to teachers because it will save them time, resources and
let them create an environment where students work is used in the creative process.
Anything that is put under the camera can be depicted and it is versatile.

It brings life to a presentation and creates a more engaging and healthy learning
environment for all the students.


The Elmo projector can display pictures in color, demonstrate a new technique and
display a book for everyone to view.

Teachers feel great about it using the Elmo and uses it in the classroom as part of
their instruction for demonstrating information

It can be used to teach students how to do certain things such as writing or forming
letters

Teachers really feel good about this technology because for one thing it saves them
the time of having to write and erase material which is time consuming.

The can have material that comes with the lesson textbooks as well as go online to
gather information.

The Decatur County school system has adopted the Elmo projector by providing all
schools in the system with an Elmo projector.

Overhead Projector was:
 First used by the police for criminal profiles and by the U.S Army for military
training. In the 1940s.

 The overhead projector became popular when Roger Appledorn introduced it to
teachers in the 1960s. A major “manufacturer of the overhead projector was a
company called 3M (Wikipedia, 2011).

 Teachers used it for instruction in order to deliver their lessons through the use of
transparency paper.

 In the 1980s and 90s, teachers used the overhead projector to present
material to students in their classrooms.

(Google, 2011)

It helped teachers to present pre-printed material and saved them time
from having to write this material on the blackboard.

Emerged from the opaque projector.

More beneficial in presenting material than the opaque projector.

It was more beneficial than the opaque projector in presenting
material and information.

The overhead projector did not require as much preparation as the
slide projector required.

Emerging Technology Elmo Projector
 Is a “document camera that displays objects that are not translucent
(WiseGEEK, 2011)” and was first developed in the 1980s but arrived
around the early 1990s because of the need for the display of information
and material without using transparencies.

 Could be used in other areas other than just education such as
business, training, and museums.

Overhead Projector

The opaque projector came before the overhead projector.

The opaque projector was invented in 1911 which displayed
images through a bright light on non-transparent objects.

Overhead Projector
In its day in education, the overhead projector experienced
increasing returns when teachers used transparencies instead
of making copies of material to pass out to the students.

Elmo Projector
The Elmo projector is becoming a part of every classroom
with the obstacle being its cost seeing the increasing
returns.

It is in competition with the interactive white board and
other computer projection presentations and digital display
or presentation technology.

Elmo Projector’s Future is based on the
following:
 Lower cost

 A smaller technology

 Provide clearer images

 Bring a classroom presentation to life.
