    General tips

    Try to find the best balance between the display quality of your content and the performance limitations of the device used for your IntuiFace experience (processor speed, available memory, . . .)

    • Users reported that several antivirus software such as McAfee or Norton Antivirus degrades performances all the time (not only when scanning or updating). Properly configuring the antivirus software may increase performances at run-time.
    • Ensure the Power Plan for your PC is not set to a power saving option when installing and running Composer and Player. Certainly, avoid running off battery power if possible.
    • Test your content as early as possible in the experience design process to anticipate and avoid problems later in your production environment
    • Keep your project simple – too many assets could result in a complicated user experience, negatively affecting performance.
    • Use collections (asset grid, carousel, flip chart, asset flow) to display multiple items in a scene rather than distributing them independently.

    Performance is affected by the number of items in your experience and any third-party applications running simultaneously. This is true not only for IntuiFace but for any third-party software application.

    Reduce the number of similar Scenes

    If you have a large number of scenes with the same layout but different content, you can replace those scenes with a single template-like scene that dynamically reads content from an Excel spreadsheet. This approach not only simplifies maintenance - e.g. when content changes, just update the spreadsheet - but it will also improve experience performance. For information about this approach, see this article.

    Reduce the number of duplicated content

    If you have the same content duplicated across several scenes (such as the home button, high-level menu or background video), you can put this content into Experience Layers. Experience layers are global to an experience and can thus appear in all scenes. They are most commonly used to create foreground and background elements that are shared across multiple scenes. The concept is similar to that of a slide show master template although experience layers offer more power and control. The main benefits are 1/ visually seamless transitions between scenes and 2/ experience size reduction. For information about this approach, see this article.

    Images

    • Image size should not exceed the pixel resolution of the target device
    • Use the "blur" effect strategically. In particular, if your design doesn't require you to dynamically change the amount of blur, we encourage you to pre-blur images using 3rd party software like Photoshop instead of using IntuiFace. If blurring with IntuiFace, the lower the pixel definition of the image and the smaller the blur radius, the better system performance will be.

    Videos

    • On Windows, use WMV codecs whenever possible as they benefit from hardware acceleration.
    • Ensure the resolution does not exceed the target display resolution or the original video content size.
    • Limit bitrate as much as possible (1500 kB/s or less should be fine most of the time).
    • Remove sound from the video if it is not used.
    • Try to avoid playing more than one video simultaneously as this can radically improve performance.
    • Use the "blur" effect strategically. In particular, if your design doesn't require you to dynamically change the amount of blur, we encourage you to pre-blur videos using 3rd party software instead of using IntuiFace. If blurring with IntuiFace, the lower the pixel definition of the video and the smaller the blur radius, the better system performance will be.

    Documents

    • Keep page size below 500 Kb (compress images in your documents with Adobe Acrobat or Microsoft Office)
    • Use the "blur" effect strategically. In particular, if your design doesn't require you to dynamically change the amount of blur, we encourage you to pre-blur documents using 3rd party software instead of using IntuiFace. If blurring with IntuiFace, the lower the pixel definition of the document and the smaller the blur radius, the better system performance will be.

    Flash animations

    • Avoid looping animations
    • Add play controls in the .swf files when possible

    Web browser

    • Avoid pages with too many animations such as embedded Flash banners

    3D models

    • Use a GPU with enough computing power and memory to handle your 3D models
