How to capture attention and build stronger brand awareness with interactive video walls

In today ’ s highly visual and digital world , large-format interactive video walls are an effective and persuasive educational , promotional and informational platform in a variety of settings . Education facilities , corporations , broadcast companies , entertainment venues and many more organisations are benefiting from enhanced engagement .
When deployed , interactive video walls increase audience dwell time and interest , create stronger brand loyalty , provide greater satisfaction for the audience and result in higher messaging and brand awareness .
A typical interactive video wall system is a combination of display technology , which could be multiple LCD flat panels or rear-projection DLP LED display cubes tiled into a near seamless display , and large-format LED Direct view displays .
The interactive component usually incorporates touch , object and gesture recognition hardware and software to create the content for the display . Regardless of the display technology chosen , the following criteria should be considered when designing an interactive video wall :
Bezel width A narrow bezel-to-bezel width provides a near seamless display when multiple panels or display cubes are arranged into a video wall , resulting in a more aesthetically pleasing display void of any discernible gaps between screens . A narrow bezel-to-bezel width results in a more accurate and responsive interactive touch experience because the gap between screens is minimal .
Image quality The display technology used must be sufficiently high-resolution so the content is clear and sharp at any angle and distance – especially close-up . A high-brightness visual display that produces vibrant images with rich colours and deep contrast also helps attract the attention of the audience – encouraging engagement with the display .
Durability Interactive video walls must be designed to withstand continuous contact on a regular , long-term basis . Options such as optically bonded , scratch-resistant glass increase flat panel durability by protecting the LCD screen . Fingerprints
left on flat panels that have a protective layer of bonded glass are easily removed with standard glass cleaner .
Rear-projection DLP technologybased LED display cubes typically have robust , easy-to-clean acrylic screens that don ' t require any additional protection . A matt finish also results in a glare-free display , which is particularly effective in high ambient light environments . More recently , field-based interactive
or gesture based systems take the user away from the actual video wall , which helps protect the screen while also increasing the viewing area .
Interactive technologies Interactivity can be added to a largeformat video wall by installing purposebuilt interactivity hardware capable of recognising touches , objects or gestures . For video walls where two or more people will be interacting with the display , the technology should be able to properly recognise multiple , simultaneous touch points . The two most common interactive technologies are imager-based and sensor-based .
Imager-based interactive technology relies on one or more cameras to detect
