This document outlines an assignment to compare and contrast the interaction methods of multi-touch screens versus mouse-driven screens. Students are asked to analyze the metaphors, interaction types, and conceptual models used in applications designed for each type of screen. They must also describe the task-domain objects users manipulate. The paper should be 4-5 pages using at least 3 quality resources, following APA formatting standards. The assignment addresses learning outcomes around cognitive principles in interfaces, conceptual terms like affordances and feedback, and researching and writing about human-computer interaction topics.
