LBE Large-Space VR / Cultural Tourism Entertainment

Let players see their bodies and real companions

Semcam Live is built for large-space VR, cultural-tourism experiences, immersive theater, theme parks, and multiplayer location-based entertainment. Fixed edge AI camera arrays capture full-body player motion, while Goku synchronously tracks controllers, props, weapons, vehicles, and interactive objects so virtual avatars, real companions, and physical touch enter one real-time data chain.

Core Value

Large-space VR should not be only “put on a headset and walk around an empty room.” Many spatial exploration and narrative touring experiences already let visitors move freely in a shared virtual space. But if the system can only represent the environment, headset, and controllers, while failing to show the player’s corresponding body or companions’ accurate body motion, presence stops at “I am looking at a world” and struggles to become “we are in this world together.” A truly embodied LBE experience needs to combine full-body motion, haptic feedback, physical props, and multiplayer cooperation, because body presence, companion presence, and physical feedback are core assets. Semcam Live makes this lighter: human motion is captured markerlessly by fixed edge AI cameras, reducing body trackers, markers, mocap suits, and venue maintenance; controllers, weapons, props, backpacks, and interactive objects that need stable rigid-body data are synchronously tracked by Goku optical tracking.

Application Scenarios

01

Multiplayer Free-Roam VR

For 2 to 12 players in the same experience, Semcam Live captures full-body posture, orientation, movement, and collaboration in real time, so virtual avatars show more than heads and hands: torso, arms, legs, formation, and motion intent become visible.

02

Cultural Tourism and Immersive Theater

For large exhibition halls, theme parks, immersive performances, and interactive story spaces, Semcam Live brings visitor motion, performer motion, prop states, and spatial events into one content system, turning a visit into an interactive, collaborative, reviewable live experience.

03

See Companions’ Body Motion

In multiplayer exploration, escape rooms, combat, and team missions, players need to read companions’ position, orientation, gestures, dodges, crouches, and swings. Semcam Live makes companions more than floating heads and hands: they become complete bodies the content system can understand.

04

Prop and Interactive Object Tracking

Goku tracks the 6DoF pose of controllers, weapons, tools, vehicles, rackets, training devices, and movable installations, keeping physical props synchronized with the virtual world.

05

Operational Replay and Highlights

Motion data can generate player reports, highlight replays, social sharing videos, and operational analytics, helping venues create stronger memories and repeat visits.

06

Scalable Venue Deployment

Edge-side processing handles complex image features and reduces pressure from sending massive raw video streams, making multi-camera matrices easier to replicate across venues with different areas, ceiling heights, and traffic flows.

How Semcam Live Supports the LBE Operations Workflow

01

Reduce Player-Worn Gear

Players do not need mocap suits or limb markers, and venues can reduce dependence on ankle, knee, waist, and other body trackers, lowering operational pressure from changing gear, sanitizing, charging, straps, numbering, pairing, and lost devices.

02

Real-Time Full-Body Multiplayer Input

Semcam Live outputs 120fps full-body motion data with latency below 0.1 seconds, suitable for driving player avatars, enhancing body presence, showing companion motion, interactive feedback, behavior logging, and on-site monitoring.

03

Goku Rigid-Body Object Tracking

For controllers, weapons, props, tools, vehicles, and interactive installations that require highly stable poses, Goku optical rigid-body tracking complements the boundary of markerless human capture.

04

Connect Physical Touch Back to VR

When players touch a physical prop, hold a weapon, cross a floor boundary, or approach a scene installation, Semcam Live body data and Goku rigid-body poses can jointly drive virtual feedback, keeping visuals, motion, and real touch more consistent.

05

Unified coordinate system and timeline

Active Center centrally manages Semcam Live AI cameras and Goku optical cameras, so player bodies, headsets, controllers, props, and scene objects are calibrated, recorded, and exported in one project.

06

Venue Operations Friendly

After fixed PoE cameras are deployed, operators mainly maintain the space, headsets, haptic vests, and props, without preparing a complete body-tracking kit for every player, making queue turnover lighter.

07

Content Engine Integration

Supports Unreal Engine, Unity, Live Link, FBX, BVH, C++, Python, and related workflows for retargeting, real-time driving, and operations data integration based on each project’s character rig.

How It Differs from Traditional Optical LBVR

Traditional optical LBVR excels at low-latency, highly stable spatial positioning, especially for headsets, controllers, weapons, backpacks, and other rigid objects. Mature optical systems typically build an ecosystem around cameras, active light markers, player accessories, and prop accessories, and emphasize scalable tracking for free-roam VR arenas. The issue is not that they are inaccurate; it is that body expression often depends on players wearing or carrying camera-visible LEDs, retroreflective markers, or trackers. Venues then need to manage straps, charging, cleaning, calibration, occlusion, inventory, replacement, and throughput. Semcam Live shifts human capture from “attach more devices to players” to “let the venue understand player bodies,” using fixed edge AI cameras to output human body rigs and motion data, while Goku handles objects that truly need rigid-body precision.

Fill the Gap of Seeing Yourself and Companions

Some cultural-tourism VR projects mainly solve spatial visuals and story content: visitors wear headsets, hold tracked devices, and walk through a shared virtual space. These experiences can create grand visual spectacle, but they may not accurately present each player’s full-body motion. Without the body, players cannot see their own leg lifts, side steps, hand waves, crouches, and evasive movements, and they have less social presence from companions’ body language. Semcam Live turns multiplayer bodies into real-time data assets, helping content move from “seeing the same scene together” toward “being present, moving, and interacting together.”

Relationship with Headsets, Vests, and Props

Semcam Live does not replace VR headsets, haptic vests, recoil props, or controllers. It turns player body motion and spatial behavior into data that can drive content in real time. The headset provides visual immersion, the haptic vest provides body feedback, props provide touch and interaction, Goku provides rigid-body poses, and Semcam Live provides markerless human motion. These data streams are synchronized in Active Center, helping projects balance immersion, operating efficiency, and scalable deployment.

What is Semcam Live?

Semcam Live is an edge computing AI markerless motion capture system. Target detection, 2D keypoints, ReID, tracking, segmentation, cropping and confidence calculation are completed on the camera side, and Active Center locally completes cross-camera matching, triangulation, 3D keypoints, body rig solving, IK, filtering, retargeting and exporting.

IndustriesWorkflow

Does body capture require wearable equipment or patches?

Human motion capture does not require motion capture suits, inertial sensors or reflective markers. If your project requires tracking rigid body objects, such as tools, props, robot ends, handles, or training equipment, you can use Goku for 6DoF rigid body tracking.

ProductsIndustriesWorkflow

When should I use real-time capture versus HPE?

The live link delivers 120fps motion output and sub-100ms end-to-end latency, making it suitable for live previews, live drives, interactions and acquisition inspections. HPE is a post-harvest high-precision processing pipeline suitable for research, training data production, key shots and projects requiring higher quality keypoint results.
