Is Rear Projection Required or Can Front Projection Work on Water Curtains?
Interactive projection on water curtains is a popular effect used in theme parks, exhibitions, and events. Water curtains act as a semi-transparent screen, allowing projections to appear suspended in mid-air. A critical question for buyers is whether rear projection is mandatory or if front projection can be effectively used on water curtains.
Rear projection is generally preferred because the projector shines from behind the water screen, resulting in clearer and more vivid images without significant interference from ambient light or water droplets. Water droplets scatter light; front projection has to deal with this scattering and the projector light reflecting off water particles, leading to reduced contrast and brightness.
Yet, cases exist of front projection use, especially in controlled environments with low ambient light and high-lumen projectors (typically 8000 lumens or higher). However, the image quality is generally lower compared to rear projection. According to industry experts, for water curtains of 3-6 meters width, rear projection offers optimal clarity and color fidelity.
Does Front Projection Work on Water Curtains in Outdoor Settings?
Outdoor environments usually have high ambient light. Front projection on water curtains outdoors struggles with washed-out images due to sunlight and reflected water droplets. Rear projection, potentially augmented with high-contrast projectors and shading, is preferred for outdoor water curtains to maintain visual integrity.
What Are the Typical Projection Brightness Requirements for Water Curtains?
Experts recommend projectors rated 6,000 to 15,000 ANSI lumens for water curtain projections, depending on size and lighting conditions. Larger water curtains (above 5 meters wide) or bright environments require projectors at the higher end of this scale, often combined with rear projection setups for maximum impact.
How Does Water Quality and Droplet Size Affect Projection Quality?
Water quality and droplet size influence the effective surface for projection. Too fine droplets create excessive scattering diminishing image sharpness, while too coarse droplets reduce the apparent screen size. A balanced droplet size (around 0.5-1 mm diameter) creates an effective projection medium. Clean water also prevents unwanted distortion or opacity.
What Is the Cost Difference Between Front and Rear Projection Systems for Water Curtains?
Rear projection can require more equipment: larger space behind the screen, protective enclosures for projectors, and possibly additional structural elements. This increases installation costs by about 15%-30% compared to front projection setups. However, the enhanced image quality and reliability typically justify the investment for professional-grade installations.
Are There Hybrid or Alternative Projection Techniques for Water Curtains?
Emerging techniques combine holographic and laser projections with water curtains, sometimes eliminating the need for strict rear projection. Some systems use ultra-short throw lenses or curved water curtain setups to optimize front projection in limited spaces, but these require specialized equipment and customization, making rear projection still the industry standard for most applications.
In summary, although front projection can sometimes work on water curtains, rear projection is the preferred and industry-standard method to achieve vivid, high-contrast images, especially in large-scale or outdoor environments. Buyers in the interactive projection field should prioritize projector brightness, water droplet control, and system layout for best results.

How to Write an Interactive-Effect Video Customisation Script ?
① Project Background: Briefly introduce the context in which this interactive scene will be used (e.g., exhibition, museum,
event space, children's area). Example: This scene is part of the “Underwater World” zone in a children's science museum,
designed to be engaging and exploratory.
②Visual Style / Atmosphere: What kind of visual mood are you aiming for? Please describe the color scheme, style, and any
references. it should focus solely on describing the visual aspects of the scene, supported by relevant charts or reference
images.
③ Interaction Points Overview：List each interactive hotspot along with the effect you'd like to trigger when the user
touches or clicks the area. example: when player touch the clownfish, it will swims away with bubble trail (animation effect)
and produce the bubble sound ( sound effect requirement )
④ Static Visual Reference：including but not limited to background image/video, a list of major visual elements (e.g., coral,
rocks, seaweed, fish), which elements should be interactive?
What about the wall/floor material for the projection？
It’s recommended to choose a light-colored material with minimal reflectivity—pure white or light grey works best. the
common material is cement & plaster board
For optimal projection results, the surface should be free of any patterns or textures, as the projector will display content
directly onto it.
There are no specific material requirements; you may use any commonly available material in your local market, as long as it
meets the above conditions.
What's Immersive Projection ？
Immersive projection refers to a technology that creates a captivating and all-encompassing visual experience for viewers by projecting images or videos onto large surfaces, such as walls, floors, or even entire rooms. This technology aims to immerse the audience in a simulated environment, blurring the boundaries between the physical and virtual worlds.
Rapidly Rotating Bouncing Sphere is an interactive space where participants jump on rotating spheres. As they step on it, the spheres surface will show special interactivity
Jumping on spheres of the same color in succession causes them to pop, releasing light particles. The more consecutive jumps, the greater the reward—caterpillars appear, and eventually, all spheres of that color burst, filling the space with light and even more caterpillars.
Indoor interactive floor projections display dynamic themed videos on the floor, commonly used in venues aiming to enhance brand influence or attract foot traffic, such as restaurants, hotel corridors, and brand car retail stores.
By using projectors and compatible software, the interactive content is projected onto the floor, encouraging engagement between people and the projected visuals. A single 5500-lumen indoor floor projector can cover an area of 5 m × 3 m. Typically, each project will use at least 3 units to ensure broad coverage and optimal visual effects.
We also offer customized design and installation support to enhance the interactive experience for your venue.
A variety of interactive games solution for your kids playing area, such as interactive small ball games, trampoline interactive games, slide interactive projection games, drawing interactive wall projection games, interactive floor games, kinect interactive games and so on. it’s interactive solutions designed based on your needs.
