Choose the right short throw laser projector for interactive walls, floors, exhibitions and digital experience spaces by comparing projection surface size, user position, throw distance, brightness, WUXGA resolution and installation geometry.
Interactive projection places people close to the displayed image. Short throw optics can reduce the projection distance and help keep the projector closer to the wall, floor or display area while still producing a large image.
Useful for exhibition spaces where walls and walkways limit projector distance.
Helps position the projection beam away from common visitor movement paths.
Suitable for larger interactive walls and floors where traditional displays may be impractical.
Supports museums, retail, education, science centers and immersive exhibits.
Before selecting a projector, define what surface will be interactive, how large the image must be and where visitors will stand or move. The surface geometry directly affects throw ratio and projector placement.
Common for exhibitions, education, digital storytelling and interactive displays.
Requires careful planning around projector height, coverage and user movement.
May require additional geometry correction and multi-projector planning.
Combines walls, floors or multiple zones into a larger interactive environment.
Throw ratio determines how far the projector lens must be from the interactive surface. Always calculate using projected image width rather than diagonal size.
| Image Width | 0.44:1 | 0.48:1 | 0.68–0.82:1 |
|---|---|---|---|
| 2.5 m | 1.10 m | 1.20 m | 1.70–2.05 m |
| 3.0 m | 1.32 m | 1.44 m | 2.04–2.46 m |
| 4.0 m | 1.76 m | 1.92 m | 2.72–3.28 m |
Interactive projection requires people to approach or enter the display area. Projector position should therefore be coordinated with visitor paths, sensor positions and the projected beam to reduce unnecessary shadows and obstruction.
Mark where visitors will stand, walk or touch before fixing projector positions.
Ceiling, wall or overhead mounting can be selected according to the interactive surface and room layout.
Cameras or sensors should be planned together with projector location to avoid blocked detection areas.
Required brightness depends on projected area, ambient lighting, surface reflectivity, content contrast and whether visitors must clearly see the image under exhibition lighting.
Suitable as a starting point for smaller controlled-light displays and retail installations.
Practical for museum exhibits, interactive walls and medium-size digital experiences.
Useful where higher brightness and more flexible optical positioning are needed.
Higher-brightness option for larger surfaces or more demanding indoor lighting.
Interactive experiences may combine maps, text, user interfaces, museum information, educational graphics, animation and detailed visual content. Native WUXGA helps maintain clarity across larger projected areas.
16:10 native format for detailed professional visual content.
Useful for visitor information, interactive exhibitions and detailed digital storytelling.
The main recommended interactive projection models use native WUXGA resolution.
Select the projector according to installation depth, projected area, ambient light and required optical adjustment rather than brightness alone.
| Model | Brightness | Resolution | Throw Ratio | Optical Positioning | Interactive Application |
|---|---|---|---|---|---|
| MX-ST4800U | 4800 lm | WUXGA | 0.44:1 | Fixed short throw optics | Small interactive walls, retail and controlled displays |
| MX-SL6000U | 6000 lm | WUXGA | 0.44:1 | Fixed short throw optics | Museum exhibits, interactive walls and medium-size experiences |
| MX-SL7000U | 7000 lm | WUXGA | 0.68–0.82:1 | 1.21× zoom + lens shift | Professional interactive installations needing flexible placement |
| MX-SL7500U | 7500 lm | WUXGA | 0.68–0.82:1 | 1.21× zoom + lens shift | Larger and higher-brightness professional interactive environments |
Digital storytelling, learning and exhibition interaction.
Motion-based experiences and visitor engagement.
Interactive historical, cultural and educational content.
Product interaction, digital campaigns and brand experiences.
Interactive learning and visual demonstration environments.
Yes. They are useful where users stand close to the projected surface and installation depth is limited.
Yes, provided the overhead mounting position, image coverage, user movement and tracking system are planned correctly.
It depends on image size, ambient lighting and surface characteristics. A 4800–6000 lumen projector can be a practical starting range for many controlled indoor applications.
No. UST can be useful for very close wall installations, while short throw projectors may provide more flexibility for larger walls, floors and exhibition layouts.
Not necessarily. A complete interactive projection system typically combines the projector with compatible sensors, cameras, tracking hardware and software selected by the system integrator.
SMX supports AV integrators, exhibition companies, interactive-experience developers, projector brands and distributors with short throw projector selection, throw-distance planning and OEM/private-label projector supply.
