The Vision
DeepScreen is a multimodal interactive system designed to provide users with an immersive sensory experience through integrated visual, auditory, and haptic feedback. It enables interaction with virtual materials that feel real.
System Components
Visual Feedback
-
10-inch LCD Touchscreen - high-resolution display for texture images and visual deformations
-
Touch input - serves as the interaction interface
Auditory Feedback
-
Standard speakers - provide complementary audio cues
-
Synchronized with touch - sound responds to interaction
Haptic Feedback
The most sophisticated component, enabling physical sensation:
Voice Coil Actuator
-
Linear actuator with stationary coil and mobile magnet
-
Forces up to 30N
-
30mm stroke for simulating hard and soft materials
Air Bearing Guide
-
Pneumatic guide for frictionless motion
-
Eliminates mechanical noise
-
Smooth, responsive movement
LVDT Position Sensor
-
High-precision contactless sensing
-
±5μm accuracy
-
Ensures reliable haptic feedback
Linear Resonant Actuator (LRA)
-
Generates localized fingertip vibrations
-
Simulates fine textures
-
Enriches tactile experience
Applications
Tele-exploration
Investigating how users recognize and differentiate materials through remote interaction.
Material Rendering
Comparing real materials with rendered versions to assess the impact of multimodal feedback.
Tele-palpation
Exploring medical applications - can doctors perform palpation examinations remotely through haptic feedback?
The Bigger Picture
DeepScreen represents the cutting edge of human-machine interaction research. Understanding how to create convincing virtual touch experiences informs everything from prosthetic sensory feedback to virtual reality systems.
