About this paper

Continuous Assessment Test for CSC 306 (Human-Computer Interaction), Department of Computer Science, University of Buea, May 2018, 60 minutes. Section A is a 7-item multiple-choice section on HCI good practice, rod/cone vision, font classification, the usability goal of efficiency, selective attention, command-line interface advantages, and stages of the human information-processing model. Section B covers true/false statements on memory for character shapes, cursive vs print legibility, memorability vs learnability, and the safety usability goal; short-answer questions on geons, the cocktail party effect, rod cells and peripheral flicker detection, and the three input/output channels of the human information-processing model. Question 4 covers user-centered design, auditory interface use cases, the concept of a metaphor with its advantages/disadvantages, and four interface metaphors (desktop, button, spreadsheet, recycling bin). Question 5 presents a flawed 'Prescription Refill Service' interface mock-up and asks the student to identify five usability flaws, discuss Miller's 5-9 chunk-capacity guideline for menu design, list two revolutionary aspects of Vannevar Bush's 1945 Memex proposal, and explain the gulf of execution and gulf of evaluation.
