HCIW/notes/2 - Interface and Interaction for IoT.md

@@ -0,0 +1,99 @@
+#### **1. New Interfaces**
+
+- Traditional point-and-click or touchscreens are less common in IoT due to:
+    - Cost
+    - Space limitations
+    - Context-specific constraints
+
+#### **2. Physical Controls**
+
+- Examples: buttons, switches, sliders, rotary knobs.
+- Serve both as input and state indicators.
+- **Advantages**:
+    - Fast, direct control.
+    - Good for precise adjustments.
+    - Accessibility for visually impaired users.
+- **Disadvantages**:
+    - Not ideal for frequently updated software.
+    - Limited flexibility when multiple control points exist.
+
+#### **3. Lights (LEDs, etc.)**
+
+- Used for:
+    - Color coding
+    - Blink patterns
+    - Quick notifications
+- **Advantages**:
+    - Non-intrusive, quick-to-understand feedback.
+- **Disadvantages**:
+    - Inefficient for complex information.
+
+#### **4. Displays and Screens**
+
+- Types: segment displays, monochrome, color screens, E-ink.
+- **Advantages**:
+    - Dynamic labels.
+    - Support for software updates.
+- **Disadvantages**:
+    - Increased cost.
+    - Feature creep (does it work without a display?).
+    - Can complicate UX.
+
+#### **5. Audio Output**
+
+- Includes sounds and text-to-speech.
+- **Advantages**:
+    - Effective for urgent alerts.
+    - Can convey emotions.
+    - No need for visual attention.
+- **Disadvantages**:
+    - Can be annoying or disruptive.
+    - Unsuitable for silent environments.
+
+#### **6. Voice Input**
+
+- Still unreliable, better for command lists than free speech.
+- **Advantages**:
+    - Hands-free interaction.
+    - Works well with good connectivity and low noise.
+- **Disadvantages**:
+    - Struggles with complex or multilingual commands.
+    - High implementation cost.
+
+#### **7. Tangible and Tactile Interaction**
+
+- Uses physical objects for control (e.g., force touch, vibrations).
+- **Advantages**:
+    - Intuitive and easy to learn.
+    - Provides ambient feedback.
+    - Good for educational products.
+- **Disadvantages**:
+    - Parts may get lost.
+    - Requires learning time.
+    - Reliability concerns.
+
+#### **8. Gestural Input**
+
+- Includes swipes, pinches, mid-air gestures.
+- **Advantages**:
+    - Suitable for video games, wearables, short interactions.
+- **Disadvantages**:
+    - Not good for precise or prolonged interaction.
+    - Risk of false positives.
+
+#### **9. Context-Sensitive Interaction**
+
+- Device responds to presence in a specific location.
+- **Advantages**:
+    - Reduces user effort in managing complexity.
+    - Effective when context directly relates to device features.
+- **Disadvantages**:
+    - Can feel restrictive if the system makes decisions for the user.
+
+#### **10. Computer Vision and Barcodes**
+
+- Includes facial recognition, biometrics, QR codes, OCR.
+- **Advantages**:
+    - Automates complex manual input.
+- **Disadvantages**:
+    - Can introduce unnecessary complexity if simpler alternatives exist.
