HCI-2

• Cognitive models


  representation of how human thinks and process information
• Goal and task hierarchies model


  breakdown of complex task into smaller steps so it design a system that are easier to use and learn and a powerful tool that designing effective system
• Linguistic Model


  enhancing natural language understanding and communication
• Physical and device model


  shaping the design and interaction between users and technology. Predict how users will interact with device.
• Ergonomics


  ensure devices and interface that is comfortable and minimize physical strain for user
• Gesture and motion interaction

  how user physically interact with devices through gesture, touch, movements
• haptic feedback


  involves sense of touch of the user such as vibration or force feedback
• physical accessibility


  users varying physical abilities. Designers focuses on creating physically accessible interface.
• device form factor


  create aesthetically pleasing design
• Wearable technology


  integrate seamlessly into user's daily life. A design that comfortable and can be worn extended period.
• Socio organizational and stakeholder requirement


  understanding the social and organizational context in which interactive systems are developed and used.
• stakeholders


  the one who the end users, designer, developers, managers, individuals. Directed or indirectly effected by success or failure of a system.
• Benefits of using goal and task hierarchies

  Identify users needs, design user friendly interface, and evaluate usability
• Benefits of using linguistic models

  natural language interfaces, personalized interaction, and enhance machine learning
• Benefits of using physical and device model

  user centered design, enhance ergonomics, and improve accessibility
• Identify users need


  by understanding the subgoal and task so it address the users need
• design user friendly interface


  hierarchy helps identify key decision of confusion, allowing design a clear and intuitive interface
• evaluate usability


  analyzing how users navigate the hierarchy can reveal usability issues in your system
• Natural language interface


  enable system to understand users input in a wat that more natural
• personalized interaction


  adapting to individual communication so it create more engaging experience
• enhance machine learning


  improve the accuracy and effectiveness of machine leaning algorithms
• user centered design


  helps designer adopt a user centered approach by considering physical aspects of user interaction
• enhance ergonomics


  understanding physical dimension and ergonomic factors of input devices that can interact with over extended periods
• improve accessibility


  models that account for physical diversity and accessibility contributing to the creation of inclusive interface. Creating adaptive solutions for users so it is accessible to a broader audience
