Latency is the time between when an action is triggered by the user and the response to that action by the projected image. The importance of this concept cannot be overestimated. In simulation applications, user interaction needs to synch flawlessly with the projected image. Unfortunately, the more processes and different components involved in a simulation system, the higher the latency will be. Which is why it’s a good idea to have a complete software and electronics backbone solution embedded in the projectors like Barco Pulse to reduce latency as much as possible.
2. Projecting on challenging surfaces
In multi-projector set-ups for simulators, badly composed surfaces can quickly lead to negative training experiences. This is where blending and warping technology comes in. Edge blending is the alignment of the projectors to remove the visible borders of the overlapping images for a seamless viewing experience. Projector warping, also called geometric correction, is the process of digitally manipulating the image data to make it look correct on the specific projection surface or shape.
With Barco Pulse, warping and blending capabilities are embedded in the projector software. Users can control their warping and blending settings directly from the projectors’ user interface, or they can choose to add their own warping and blending solutions via the Barco Pulse command protocol (JSON-RPC). Geometry corrections performed in the projector only add minimal latency, since all image processing is done in one single step through the proprietary Barco SSP technology.
3. Smooth fast-moving content
While high resolution is important for image detail, it’s often the ability to display images at high speed that makes a true difference in realism. In applications like flight or driving simulation, even the fastest moving scenarios need to be realistic.
Barco Pulse gives customers that extra bandwidth, which allows the projector to take input signals up to 4K @ 240 Hz or 8K @ 60 Hz for true-to-life image response and better ergonomics without image artifacts. Especially when displaying very fast-moving content, the images will appear a lot smoother in the 240 Hz system, as 60 Hz simply lacks the needed information to clearly visualize the objects. More frames per second improve the smoothness of motion and give more resolution and clarity. This increases the immersive feeling.
