Integration Overview

Polycom offers two distinct ATX software solutions:
The ATX SDK version 2.0 enables the AV integrators to add more value to ATX 200, ATX 300, and ATX 400-based solutions by allowing the integrators to support the unique requirements of their customers. The ATX SDK version works in conjunction with special control panel code (provided by the control panel vendor), enabling AV integrators to customize the Touch Panel user interface to the specific needs of their customers.
1
The ATX 300 version 2.7 provides a user interface with the same feature set as the standard Polycom Immersive Telepresence software, including the Touch Panel with Enhanced user interface capabilities. Rather than the Enhanced user interface, customers can opt for the Classic user interface, which maintains the look and feel of the ATX version 2.0 user interface, but does not include the new version 2.7 features. Note that a 10-inch Touch Panel is required for the Enhanced user interface.
For additional information regarding the differences between ATX SDK version 2.0 and ATX version 2.7, refer to the Polycom Architected Telepresence Experience ATX/ATX SDK Technical Specifications.

Note that the information is provided here as guidelines only. These guidelines allow you to create a highly immersive, real-size, telepresence solution for a typical conference room with a rectangular table. Integrators may also achieve high quality telepresence solutions based on the ATX platform in a wide variety of room sizes, table shapes, and seating arrangements.
Ultimately, the quality of experience for a telepresence solution involves a multitude of factors ranging from furniture design, camera placement and angles, display technology, room lighting and acoustics, and many other factors. While Polycom does not provide design consulting services, we do work very closely with our certified ATX partners to ensure success of their designs. Polycom is not in a position to guarantee or otherwise warrant that a proposed design will meet the expectations of the customer.

Selecting the Room, Displays, and Table

To achieve the most realistic immersive experience, you must select the appropriate room and furnishings as described in this section.

Selecting the Room

When selecting a room in which to install the ATX 200, ATX 300, or ATX 400, you must take a number of factors into consideration. For example, besides

Installing the Displays, Table, Cameras, and Chairs

Selecting the Displays and Table

The list below provides the basic information you need when choosing your displays and table. Following these guidelines will enable you to create a lifelike immersive telepresence experience. However, you may decide to make changes depending on your particular situation:
The displays should be between 58" to 65" in diagonal size.
Each display must have an HDMI input.
Each display must be able to go into Sleep or Standby mode when no
video is received. Additionally, each display must be able to wake up from Sleep or Standby mode when video is received.
The displays must be able to support 1920 x 1080 resolution @ 60Hz without overscan or underscan.
The table must be rectangular.
Note that you can use more than one rectangular table and set them up in a non-rectangular seating arrangement as shown in Figure 2-3.
As shown in Figure 2-1, the table width required to capture two people is 53" (134.6 cm). The space between the cameras should be between 3" (7.6 cm) and 6" (15.2 cm).
As shown in Figure 2-1, the table must have a minimum width of 115" (292.1 cm) for ATX 200 rooms, 171" (434.3 cm) for ATX 300 rooms, and 227" (576.6 cm) for ATX 400 rooms.
If you choose to add content display(s), Polycom recommends selecting LCDs. You can select plasma displays, but they are subject to burn-in from the Polycom logo that appears when content is not being shared (if that option is selected). If you do choose plasma displays, be sure to power off the content displays when they are not being used.
Note that these guidelines do not apply to ATX SDK solutions. They should be adjusted to fit your room size, table shape, and seating arrangement.

Determining the Placement of the Displays and Table

To properly align the cameras, you should correctly place the displays and table relative to each other. These are the guidelines you should follow:
The displays must be mounted on a wall so that they are horizontally aligned and positioned next to each other with no space between the bezels.
The displays must be mounted so that the bottom edge of the active video on the displays is at the same height as the tabletop. For example, if the tabletop is 30" (76.2 cm) high and the displays have a 2" (5.1 cm) bottom bezel, then the displays must be mounted so that their bottom edge is 28" (71.1 cm) from the floor.
The distance from the rear edge of the table to the front of the displays should be 110" (279.4 cm). Figure 2-2 shows the fields of view from the cameras when the table is placed at this distance in an ATX 300 room. Note that the center camera does not capture all the participants completely.

Installing the Displays, Table, Cameras, and Chairs
The table must be centered with the vertical center of the middle display.
For non-rectangular seating arrangements, you need to provide the
vertical and horizontal fields of view along with the table size into a CAD package. The target is for the sight line to be perpendicular to the table edge and to the people in the room.
Note that the camera line of sight is perpendicular and intersects the tables at their mid point.

For ATX 300 only, if the room is large, you can choose to place the table farther than 110" (279.4 cm). By moving the table out to 126" (320 cm), you will be able to completely see Seats 1 through 6 when the center camera zooms out for the full room view, as shown in Figure 2-4. Note, however, that by moving the table farther than 110" (279.4 cm), the participants will appear somewhat farther from view on the far end of the conference.

Installing the Displays, Table, Cameras, and Chairs
If, due to room restrictions, you must position the table closer than 110" (279.4 cm), the field of views will widen and, therefore, overlap more than normal. Figure 2-5 shows the overlap in an ATX 300 room. This increases the likelihood of a person appearing on two displays at the same time. For example, if a person seated at Seat 2 backs up or moves to his/her right, the people at the far end will see that person on two displays at the same time. If you move the table as close as 84" (213.4 cm), Seats 2 through 5 may not appear completely on camera in calls in which only one camera is used to capture Seats 2 through 5.
Note that placing the table closer than 110” will prevent the camera from capturing the outside participants.

Installing the Displays and Table

Once you have determined where to place the displays, you can install them on the wall. After installing the displays, place the rear edge of the table 110" (279.4 cm) from the front of the displays. The table should be parallel to the displays and the centerline of the table should align with the centerline of the displays as shown in Figure 2-6.
Figure 2-6 Placing the Table Relative to the Displays
(Top View) in an ATX 300 Room

Installing the Cameras

The ATX comes equipped with Polycom EagleEye 1080p cameras. When installing the cameras, you must center one camera above each display. You can either attach the cameras to the wall above the displays or you can install the cameras on top of the displays; however, Polycom highly recommends attaching the cameras to the wall. By doing so, the cameras are less likely to become misaligned if the displays get bumped.
Whether you are planning to install the cameras on the wall or on top of the displays, you must first attach them to the Polycom EagleEye 1080p shelf (part number 2215-24143-001). For information about how to attach the cameras to the shelf and how to mount the shelf to the wall or to the displays, refer to the Setting up the Polycom EagleEye 1080p Shelf document (part number 1725-28622-002) provided with the shelf.

Installing the Displays, Table, Cameras, and Chairs
The camera should be placed on the center of the captured image rather than the center of the display as shown in Figure 2-7. This makes the camera line of sight perpendicular to the table edge.

Creating the Camera Alignment Marks

To create the camera alignment marks:
1 Ensure that the vertical centerline of the table aligns with the vertical
centerline of the middle display as shown in Figure 2-6.
2 Determine the table length required to capture two people on camera in
seating positions. The recommended width is 53" (134.6 cm).
3 Determine the separation distance between the captured field of view.
The recommended distance is 6" (15.2 cm).
Keep in mind that the wider the distance, the further it takes before the cameras’ field of views overlap.
4 Adhere painter’s tape to the top of the table to create the camera
alignment marks as shown in Figure 2-8.
Note that all the cameras are normalized to the same width so that they all have the same scaled factor.

Installing the Displays, Table, Cameras, and Chairs

Placing the Chairs

As shown in Figure 2-2, where a conference participant is seated affects where and how they appear on the displays at the far site. To ensure that the conference participants appear on the displays, but that they do not appear on more than one display, you should place the chairs at the proper locations at the table and mark those locations.
To help participants keep their chairs at the proper locations at the table, Polycom recommends that you use one or more of the following visual or physical markers:
Place placemats on the tabletop at each of the proper chair locations.
Mark the tabletop or the floor to indicate where the chairs should be
positioned.
Attach barriers under the table so that the participants cannot physically move their chairs to an incorrect location.
Additionally, the chairs you select must not exceed the following dimensions:
Arm span: 24½" (62.2 cm)
Wheel base: 27" (68.6 cm)
