Human Computer Interaction (IT-803 (B)) - Important Questions

Explain the structure and components of human memory. Distinguish between sensory memory, short-term (working) memory, and long-term memory with examples relevant to user interface design.

Discuss the implications of human memory limitations for user interface design. Describe at least five design guidelines to accommodate memory constraints (e.g., recognition over recall, progressive disclosure).

Explain the multi-store model of memory (Atkinson-Shiffrin). How is this model relevant to designing effective user interfaces?

Differentiate recognition and recall as memory retrieval processes. Explain how recognition-based interfaces reduce cognitive load and provide examples from real-world interfaces.

List and explain the human input and output channels. For each channel, give examples of interaction devices and discuss primary design considerations for HCI.

Compare visual and auditory channels in terms of bandwidth, persistence, error susceptibility, and suitability for different types of information in HCI. Provide examples of when each channel should be preferred.

Explain the role of haptic feedback as an output channel in HCI. Describe situations where haptic feedback improves usability and discuss its limitations.

Define Human-Computer Interaction (HCI). Discuss the primary goals and scope of HCI with suitable real-world examples.

Explain Norman's seven stages of action. Apply these stages to a common interface task such as composing and sending an email, identifying potential user breakdowns.

Describe the concepts of mental model and system model. Explain how discrepancies between the user's mental model and the system model affect usability, and discuss strategies to reduce such mismatches.
