Floors, walls, and tables that respond to the audience

Projected floor: light, shadows, and detection

The floor receives projector light while detection follows a separate route. Draw the beam and sensor field with people/scenery: projection shadows and detection blind zones may occur for different reasons.

• Optics: area, throw distance, lens, permitted orientation, and ambient light. Select model/mount with its owner; not every projector can point at a floor.
• Surface: material, color, texture, and reflections. Review content legibility and traffic with the venue owner.
• Interaction: map coordinates, create zone boundaries, and choose responses visible from above and entry points.

Proposed rehearsal: one standing person, slow steps, crossing people, and event lighting. Distinguish visual shadow from missing data before recalibrating. Broad ripples may tolerate occlusion better than small targets, depending on intent.

Fallback keeps a useful visual scene without tracking and permits manual assistance. Recheck mapping if optics, sensor, or surface moves. This route does not use LED-floor mechanics or establish physical floor suitability because video works.

LED floor: picture, sensors, and application

A video floor does not necessarily detect steps. ROE Visual Black Marble Interactive exemplifies integrated interaction; other systems may need external sensors. Confirm the exact model before designing the response.

Draw three maps: video distribution, detection zones, and application coordinates. BrightLogic documents sensor exclusion/calibration for compatible variants. Disabling interaction does not change floor use conditions.

• Test step, dwell, movement, intended clothing/objects, and multiple people on the specific system. Sensor count is not participant count.
• If video works without response, review data and application separately before changing image processing.
• Prepare a visual-only mode and operator supervision. Coordinate cleaning, edges, and circulation with installation/venue owners.

Loads, supports, wheels, footwear, and use suitability belong to the documented assembly and its owner. This complements the LED-floor rental guide retaining system/surface requirements. A documented LED-floor project does not prove it used tracking.

Wall: presence, gesture, or touch

Choose approach, midair hand movement, or contact. These are different actions: someone facing the wall may not intend activation. The invitation zone must make the action understandable.

• Separate waiting/active zones; define spectators passing behind and another participant entering.
• Place targets/gestures for different heights and seated participation. Offer a button/operator without requiring raised arms.
• Confirm touch display versus external tracking. Sensor view must remain clear of body, furniture, and decoration.

Proposed rehearsal: approach, valid gesture, ambiguous gesture, exit, and two people. Confirm selection visually and show return. Adjust target size/dwell to task; do not demand pointer precision from presence-only detection.

On tracking loss, remove cursor/effect and return to idle, rather than moving to canvas origin. Installation, fixing, and circulation approval remain with their owners. Test actual lighting/background before advertising contactless interaction.

Touch table: multiple people without conflicting control

Device contact maximum differs from participant count. Microsoft documents a reported digitizer maximum; OS, driver, and application must also process the required contacts.

• Separate personal/shared zones; define object ownership and release when a finger leaves.
• Orient text/controls for each side, keep actions reachable, and provide a touch-free alternative.
• Test simultaneous touches, accidental palm, two hands on one object, and lost contact. Detected touch contacts do not, by themselves, identify the person.

Proposed rehearsal: one user, then several doing the same tasks. Check a stuck control cannot block reset and approved cleaning does not trigger actions. Manufacturer specifies cleaning materials/method; operation organizes pauses/assistance.

If a touch zone fails, the operator may disable that function and use assisted mode as designed. Table/support must suit the intended orientation/use; placing a display horizontally does not automatically make it a public-use table.

Choose the surface by action and viewpoint

Compare pictures from participant and spectator positions. A top-view effect can distort in perspective or be hidden by a body. Interaction alone cannot fix an unreadable picture.

Agree light, scale, detail, delivery resolution, and audience positions before selecting equipment. Optical design, loads, and installation require their owners and exact models. If detection does not fit the space, compare another action/surface while preserving intent. Video equipment guides and the LED-floor guide complete technical selection.
