Presentations can be difficult in most cases where there are a lot riding on the outcome, the last thing I want to be worrying about is the audio visual component. This article will present some basic guidelines that will help you set the screen layout space in order to obtain the highest quality projection from the presentation.
General guidelines
Display
For optimal viewing, the audience should be seatedwithin:
30 degrees to a line perpendicular to the center of the screen.
They should then be seated at a distance twice the height of the image.
Note: (If this can not possibly take into account multiple viewing options for the public).
Content Type
Entertainment - The last line should be no more than eight times the height of the image.
Corporate - The last line should be six times the picture height.
Critical Applications - The last line should be four times the imageheight
Display setup
To avoid the obstruction of vision is bottom of the screen should be about four feet (1200mm) above the floor. If the seat is offset, or if the floor is tilted, you can adjust it accordingly. Try to avoid setting the high screen. The ergonomics associated with a comfortable viewing indicate no viewer should have to turn the head more than 30 degrees from the straight, or tilt your head to no more than 25degreeshorizontal.
Seats
The design of the seat is very important to allow viewers to obtain full view of the projection. Often, the staggered arrangement of the seats is more suitable for most situations. As a general rule in a row, with a minimum unobstructed horizontal clearance between the lines lead from the front of a place not occupied at the rear of the seat in front. This game can vary but is typically 16 inches (400mm). Corridors shall be provided so that there are no moreseven seats, one between the seats and a hall. The ports of entry and exit should be considered when designing the layout of the seats. The layout is designed to:
Allow for easy entering the room
Allow quick exit in an emergency
The line contains no more than 100 seats;
Each port is no more than three lines.
Aisles must end in a cross-corridor.
Front or rear projection?
There are a variety of factorspossible to determine whether the front or rear projections are best suited for your presentations.
Front Projection
Front projection can generally provide a wider viewing angle of projection. We require: controlled lighting (ambient light must be kept off the screen to eliminate a reduction of contrast ratio).
Requires either a projection room at the back of the theater, or a platform or mount the projector (s) in the theater. Note that the latter is apotential source of noise.
The projection geometry must be carefully designed to achieve the best compromise between image distortion and blocking the path of light by the public.
Must be accessible for maintenance. A projection room must be free of dust (positive pressure preferred), and have adequate ventilation.
Projection
Projection generally has a more limited projection angle front - as long, narrow rooms.
Can be viewed with greaterroom lighting levels, and are less immune to "wash" lighting environment.
Available in flexible and rigid materials. A rigid screen is more expensive than a front projection screen, and size restrictions.
Requires space behind the screen. Mirrors can be used to reduce the required depth. Must be accessible for maintenance.
Rear projection room must be free of dust, and have adequate ventilation.
To decide whether front or rear projection will enhance your presentation,ask yourself, 'What kind of presentation I will give' and 'What is the purpose of presentation'. For example, if the presentation is "canned" can be considered the front or rear projection. If a speaker is the live interaction with the presentation, rear projection is best so that the speaker can interact with the images without being in the light path of the projector. In addition, lighting allows more room allowed to take notes, etc.
ScreenWidth
Determine the minimum height of the screen depending on the distance of the farthest viewer and the height of the ceilings. This figure may be adjusted based on demand (eg demand entertainment will require a larger screen than the minimum for the impact).
ADA Requirements
When the necessary arrangements will be made for participants who require wheelchair access, and / or have visual impairments or hearing accessibility and sizeof these spaces is defined as:
A minimum number of aisle seats will be required to have any arm aisle or aisle side armrest that folds up. Some additional signs may be required. The audio system will require the addition of an acoustic-assisted. Your emergency systems may require the addition of strobe signals or visual messaging systems. Your videos and other visual presentation systems may require captions.
MiscellaneousConsiderations
Equipment location
It is very important to prevent damage. This is usually but not always, located at the projector (s). This projection device can include controllers, controller of entertainment, video and audio equipment.
Adequate supply
Do not forget to provide adequate electrical power for this equipment and the projector (s). Do not forget to enable channel power cables, control signals, etc. Formeeting rooms and meeting rooms will also want to provide accessible sources (such as VCRs and DVD players).
Aesthetics or Theme
If you need speakers and other equipment are hidden?
How did your presentation?
Automatically,
Public demand,
Host-demand and live presenter (may require random access control or other interaction).
Whether your presentation is for the boss or a big company, taking a moment to plan how youI would like to provide the information may make a significant difference to the public. So take a moment an examination which they mean, as you would like to say and how is the best way for your audience to receive it. You could make the difference between winning new business or losing it.
