Scratch Me with Lidar Sensor

Project Overview:
Scratch Me with Lidar Sensor is an interactive installation developed in Unity, designed to engage attendees through a playful scratch-and-reveal experience. Installed at ground level, the project used a Lidar sensor to detect user movements across the surface. As users “scratched” the screen with their feet or hands, hidden messages were revealed, offering a dynamic and memorable interaction. The project seamlessly blended cutting-edge sensor technology with gamified interaction to captivate audiences and promote user engagement.

Methodology:
Game Development:
Platform:
Developed in Unity, the application ensured real-time movement detection, scratch visualization, and message reveal animations. Unity’s flexibility allowed for the creation of highly responsive and visually dynamic scratch surfaces.

Game Components:
Mechanics:

• Lidar Sensor Detection: A Lidar sensor accurately tracked user movement on the ground-mounted screen, interpreting physical interactions as scratch actions.

• Scratch Screens: Users scratched different areas of the screen, gradually uncovering hidden messages underneath.

• Message Display: As scratching continued, personalized or branded messages were dynamically revealed, creating an element of surprise and engagement.

User Interface Development:
Intuitive Design:

• Natural Interaction: The scratch mechanism felt intuitive and required no instructions, encouraging spontaneous participation from users of all ages.

• Smooth Visuals: Real-time scratch animations and seamless message reveals enhanced the overall experience, keeping users entertained.

• Immediate Feedback: The system instantly responded to user movements, ensuring a lively and interactive session.

Testing and Validation:
Performance Optimization:

• Conducted extensive testing to ensure the Lidar sensor consistently and accurately detected a range of movements.

• Verified real-time response without lags, even with multiple users interacting simultaneously.

• Fine-tuned scratch sensitivity to balance user effort and message reveal timing perfectly.

Deliverables:

• Unity-Based Application: A robust application integrating Lidar sensor input, scratch effects, and real-time message display.

• Scratchable Screens: Custom-designed digital surfaces that created a rewarding and playful scratching experience.

• Dynamic Message Reveal: Hidden messages that were revealed interactively as users engaged with the screen.

Conclusion:
The Scratch Me with Lidar Sensor project successfully combined innovative sensor technology and interactive gamification to deliver an unforgettable experience. By allowing users to physically engage with a scratchable digital surface and uncover hidden messages, the installation captured attention and created lasting impressions. This project demonstrated a creative use of Lidar technology within Unity, emphasizing real-time interaction, user enjoyment, and cutting-edge experiential design.
