Heartbeat Of A City: Tech Rider
Concept
A walkable projection-mapped installation that translates urban history into an embodied experience, where each step advances time and reveals the evolution of a fictionalized port city merging Singapore and San Francisco.
Setup
The installation consists of a linear, hallway-like environment with a projection-mapped ground plane approximately 20 feet in length. Visitors walk along this path, triggering real-time visual changes through embedded floor sensors. Each 2-foot step advances the timeline by 10 years, allowing participants to physically navigate 100 years of urban transformation.
The system integrates an Arduino-based sensing array beneath or along the walking surface, connected to a central workstation running Unity and TouchDesigner. Overhead projectors (2-3 units) or a continuous display system are used to map visuals across the full length of the floor. The setup requires precise calibration for projection alignment, edge blending, and sensor responsiveness.
Lighting
- Requires a fully dark or black box environment to ensure projection clarity and contrast.
- The space should minimize ambient light, as the primary visual focus is the projected ground plane.
- The installation itself will be the primary light source.
Space Requirements
Ideal: 20 ft (length) x 4 ft (width)
Minimum: 10 ft x 4 ft
Minimum: 10 ft x 4 ft
- Requires a long, continuous floor surface with adjacent vertical surfaces (walls) to emulate a corridor or hallway condition.
- Clear overhead space is needed for projector mounting and alignment.
Sound Requirements
- The installation includes ambient and reactive audio tied to movement and timeline progression.
- Audio is immersive but moderate in volume and should not significantly disrupt nearby works.
Can be presented either through localized speakers or headphones depending on exhibition constraints.
Can be presented either through localized speakers or headphones depending on exhibition constraints.
- Preferably placed in a semi-controlled acoustic environment to preserve sound clarity.
Venue
- Designed for an indoor gallery or black box exhibition space.
- Requires controlled lighting and sufficient ceiling height for projection setup.
- Ideally installed within a dedicated section of the gallery to maintain immersion and spatial continuity.
- Qualcomm Institute (Spatial Computing Lab), Design Lab, B114
Power
Requires approximately 4-6 power outlets for:
- 2-3 projectors
- 1 workstation (PC)
- Arduino/sensor system
- Speakers or audio equipment
- Continuous power required throughout exhibition duration.
- No major battery-dependent components, but occasional access for maintenance and recalibration is needed.
Safety
All cables must be secured and safely routed to prevent tripping hazards, especially around the walking path.
Floor sensors and surfaces must be stable and flush with the ground.
Floor sensors and surfaces must be stable and flush with the ground.
No hazardous materials, sharp objects, or dangerous equipment involved.
Overhead projectors must be securely mounted.
Operation
The installation runs continuously once powered and initialized.
Requires:
- Daily startup (power on system, launch software)
- Occasional calibration of sensors and projection alignment
- No constant supervision required, but periodic monitoring is recommended.
Audience Interaction:
- Visitors (1 by 1) walk along the path at their own pace.
- Each step triggers time progression and visual change.
- No instructions needed beyond simple entry guidance.
Anything Else
Installation requires 2-3 days for setup, including sensor calibration, projection alignment, and testing. The work benefits from uninterrupted linear flow, so crowd management may be considered to prevent congestion on the path.
