• provide interaction model which provides usable and efficient interaction and results higher productivity

Factors considered by HCI designers

2 factors

• functionality: set of actions or services it provides to its user
• usability

components

• computer science - study of process that interact with data if form of programs
• Human factor Engineering - study of how people use system or equipment for designing , developing , creating tech
• Cognitive Science - study of mind intelligence and learning

Multimodal HCI implementation

• responds to input in more than one modality or communication channel
• rg: speech, gesture ,writing and others.
• used to construct variety of interfaces for different app using advance HCI
• two component
