Design Changes Affect AV Placement

Design Changes Affect AV Placement ….It was a perfectly designed AV System for a meeting space. At the touch of a single button, a state-of-the-art laser projector would quietly drop from a disguised ceiling tile. Displaying content optimally scaled to meet the viewing requirements of the room’s occupants throughout the collaborative space. The equipment order had been placed and the trades were scheduled.

And then, deep into the project; a request was made to change a prominent light fixture and consequently, its location.

It’s new position places it directly in front of the projector.  It may not sound like a serious issue but repositioning the projector may require a specialized short or long-throw lens be added. The electrical drop may also need to be relocated, along with moving any other affected ceiling features. Audio visual systems are an integral part of room design and changes to a room’s walls, ceiling, flooring, lighting or furnishings may have a ripple effect that could result in costly change orders and extend your project’s timeline.

Change orders happen and for a variety of reasons

Design Changes Affect AV placement and configuration. Collaborative video conferencing-enabled spaces will feature either a flat panel display, videowall or projection system, along with microphones, speakers, AV equipment and room control device(s). These elements are an engineered system, each with precise locations carefully documented. If, for example, a change is made regarding the conference table size, additional in-ceiling speakers or microphones may be required. Placement of these components may likely affect other ceiling features. This could include fire sprinklers, HVAC, occupancy sensors and lighting fixtures. Switching conference room table sizes also changes the locations of the floor boxes for power and connectivity. While these issues can be resolved through redesign and coordination with other trades, clearly they will impact the project’s timeline and budget.

Furniture that was specified months earlier may have been discontinued or the designer or client may have requested a change.  Regardless of the circumstances, collaboration among stakeholders at the onset of change is the key to successful project outcomes.

Selecting the Best Conference Display

Selecting the Best Conference Display  …Effective communication and collaboration relies on the participants’ ability to comfortably engage with the shared content. Content should be visible and any text being displayed, legible from any seat in the room. Determining the proper display size, type and placement is key in creating an engaging collaborative environment.

Consider the technology early in the planning phase.

This allows for the most flexibility in design options and provide the best possible outcome. An analysis of the requirements and goals will help in determining the ideal display for the space.

Viewing Distance Drives Display Type

There are various methods to determine proper viewing distance and screen size. The commercial AV industry association, AVIXA (Audiovisual and Integrated Experience Association), offers the specification “ANSI/INFOCOMM V202.01:2016, Display Image Size for 2D Content in Audiovisual System. The standard uses multiple calculations that factor content, viewer positions from multiple locations, image size, font size, ambient light, off-axis viewing, the human eye’s range of sight at various angles, and more.

Selecting the Best Conference Display – Calculating for Content

Calculations for huddle spaces and small-to-medium conference rooms… Using a multiplier factor can provide a close estimation of display size that can help guide the design. Screen size and distance calculations are directly impacted by the content. However, because the type of content dictates the multipliers (or factors) used in the calculation.

Spaces where presentations will be shared, a large image will allow participants to read the content more clearly and comfortably. To calculate for this scenario, use a multiplier of 6 times the display’s image height (based on 1920 x 1080P resolution) to determine the furthest seating position. If data-rich content such as CAD drawings, Word or Excel documents or Web pages are to be shared, a factor of 4 should be used for added clarity. In conference rooms using video conferencing, a multiplier of 4 is also recommended.

The 45° Rule of Thumb

Viewing angles are a critical consideration.  A general rule-of-thumb, participants should be within 45 degrees from the center of the screen. The top of the screen should be within 30 degrees above the audiences’ eye level. AVIXA’s standards are much more detailed. However, this general guideline will help set the expectation of screen size and positioning for initial design purposes.

Aspect Ratio

Widescreen aspect ratios of 16:9 are currently the most common. Laptops have also landed on 16:9.

By providing a screen that maximizes your content, your participants will remain engaged and your meetings will become more productive. Do you have a meeting space that could benefit from a more engaging video experience? Call us for a complimentary on-site assessment.
