ADVANCED COMPUTER DEVICES (SENSORY & INTERACTIVE TECHNOLOGY)
These devices are mainly used in:
Virtual Reality (VR)
Augmented Reality (AR)Human-Computer Interaction (HCI)
Robotics & Simulation
📌 1. HAPTIC GLOVES ⭐
🔹 Definition:
Haptic Gloves are wearable devices that allow users to feel virtual objects through touch (feedback).
🔹 Key Feature:
Provides force feedback / vibration
Simulates real-world touch sensation🔹 Uses:
Virtual reality gaming
Medical training
Robotics control
👉 Exam Point:
Haptic = Sense of touch
2. TACTILE DISPLAY
🔹 Definition:
A Tactile Display is a device that converts digital information into physical touch patterns.
🔹 Key Feature:Used by visually impaired people
Displays Braille-like output
🔹 Example:
Refreshable Braille display
👉 Exam Point:
Tactile = Touch-based output device
3. VOICE RESPONSE UNIT (VRU)
🔹 Definition:
A Voice Response Unit (VRU) is a system that allows users to interact with a computer using voice or keypad input.
🔹 Key Feature:
Converts voice ↔ digital signals
Used in automated phone systems🔹 Example:
Customer care helpline (“Press 1 for English”)
👉 Exam Point:
VRU is part of IVR (Interactive Voice Response) system
4. DATA GLOVE
🔹 Definition:
A Data Glove is an input device worn on the hand that captures hand movements and gestures.
🔹 Key Feature:
Uses sensors
Tracks finger movement🔹 Uses:
Virtual reality
Motion capture
Gaming
👉 Difference:
Data Glove → Input (captures movement)
Haptic Glove → Output (provides feedback)
