I. Theoretical Background
A holographic projector is a unique display system. The holographic projector system embodies a top of the range full High Definition Hologram Projector with an in-house computer system capable of feeding the projector with fully uncompressed video files. It consist of two technologies namely, the holography and the projector.

Holography is a method which allows three-dimensional images to be made. It includes the use of a laser, interference, diffraction, light intensity recording, and suitable illumination of the recording. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object are still present, therefore making it three-dimensional. The projector that will be used in this project is a overhead projector. An overhead projector is a variation of the common slide projector that is used to display images to a group of people.

II. Project Description
Hologram Projector is a projector wherein it can reflect the full dimension of an image. It consists of a laser, interference, and diffraction, light intensity recording and suitable illumination of the recording.

Hologram Projector is AC operated. It projects special white light or laser light. The light produces two- and three-dimensional images. Authentic 3-D images require laser-based holographic projectors. It can be presented from different angles and can be seen in true perspective.

III. Process Description
To come up with the Hologram projector’s design wasn’t easy. The group had to go through several brain-storming sessions and researches to come up not only with an appropriate but also a hi-end design that will embody the concept of the new technology. The drafts of the prototype’s design were drawn in a three-dimensional view. The designs created varied from rectangular to circular shapes. After choosing the best design that has met the specifications, the image was then rendered using Autodesk Maya, a 3D animation software. Upon the completion of the design, the creation of the prototype immediately followed.

IV. Assembly and Testing
These are the procedures on how the hologram projector assembled:
1. Screw the main circuit board and the power box at the base. Then, connect the wire for the plug.
2. Place the frame of the USB ports at the “side 2” and “side 3” of the base. Connect it to the main circuit using a small wire.
3. Near the USB port of the “side 3”, screw the exhaust fan and connect it to the power box.
4. The lens, laser and the buttons were screwed at the cover plate. Connect them to the main circuit.
5. The cover plate will be placed at the top of the base and screwed.
6. Place and screw the 3 piece of rectangular plastic that serves as the lock and stand for the projector.
Once the assembly was done, the hologram projector was tested by inserting a flash disc with images inside.

V. Discussion
1. When the Hologram Projector was first tested, there were some assembly problems that caused the projector to work functionally. It was suspected that some screws may be loose while assembling the projector. This problem can be solved if the process was given enough time for it to be built.
2. During testing, the hologram had malfunctions when it comes to displaying a full 3D view of the images. There were some hallow parts when displayed. It could be because of the mirrors that were used, the group suspected the quality and stability of the glass that caused this.
3. The dimension of the 3D image was smaller than expected, probably since the equipments used were not best in quality. It is suggested to use equipments that are beyond good quality to preserve the image’s value and characteristics.

...ADVANCED COMPUTER APPLICATIONS MODULE DEFINE A COMPUTER * An electronic machine that works under the control of stored programs to accept, process & output data/information for use by the operator. * A device that accepts data, processes the data in accordance with a stored program, generates results, and usually consists of input, output, storage, and arithmetic, logic, and control units. * A functional unit that can perform substantial computation, including numerous arithmetic operations or logic operations, without human intervention during a run. * It is an electronic device/machine that accepts data (raw facts & figures) as input and processes (works on it) to produce information (data converted to meaningful form) as output. The computer is made up of hardware, software and peripheral devices. Hardware- refers to the tangible, physical and mechanical components of a computer. Software- refers to the intangible computer components, which are the programs or instructions of the computer. Everything that a computer does, it acts under instructions written out as computer programs. The hardware needs these instructions to function Computer program: * A set of instructions, written in a specific programming language, which a computer follows in processing data, performing an operation, or solving a logical problem. See also software. * A computer program is a set of statements or instructions to be used directly or indirectly in a computer...
