Conversational interfaces

At the forefront: Various modes collaborating. Users engage naturally through voice, vision, gesture, and text, while systems grasp context across modalities.

🎯 Key Insight: Different modalities do not substitute one another; they exist together. Text remains crucial alongside voice and vision. Optimal experiences incorporate various modalities tailored to specific situations.

Three Interaction Paradigms

Aside from content formats, the way users engage with systems has progressed through three paradigms, each showcasing a deeper comprehension of user context and devices.

Screen-Centric Interaction

In the traditional web model, interaction occurs on screens via clicking, tapping, and entering information into forms. The system relies on a stationary display, keyboard or touchpad, and the need for user participation in all tasks.

💻 Interaction on screens
🖱️ Clicks, taps, forms
👁️ User actively engaged
🎯 Explicit interaction needed

Device-Aware Interaction

In the modern paradigm, systems identify the device they are operating on and adjust their interactions accordingly. Each device, whether desktop, phone, tablet, watch, or TV, has unique capabilities and limitations, allowing for intelligent adaption of the user experience.

📱 Knows device type
⚙️ Understands capabilities
🔄 Adapts to device
✨ Smarter interaction per device

Environment-Aware Interaction

The new paradigm involves systems that can recognize and react to the user's surroundings, including location, time, light, proximity to others, and current activity. This shift enables interactions to be more anticipatory and seamless, eliminating the need for direct user input.

🌍 Understands location & context
🔍 Responds to surroundings
⚡ Proactive, ambient
✨ Context-appropriate responses

💡 Design Implication: Modern experiences must be able to function seamlessly across all three paradigms. This includes offering specific interactions for users who are focused on their screens, adjusting to various devices, and presenting information based on context in a proactive manner.
