Software products that serve the users’ needs and goals: CS820 Usability and Interaction

Course Overview Investigates what qualities of a software product make it usable How does one include usability concerns throughout the software lifecycle How does one design for usability Determine experimentally the usability of a product, and the importance of early usability testing on a simple prototype

Course Objectives Qualify and quantify what is commonly meant by “usable” Identify a means to inject usability attributes into each phase of the software development lifecycle in a way that is appropriate for that phase Develop usability criteria for a product Discuss and develop ethical guidelines for products and user testing Design a usability experiment for a product. Analyze data collected from a usability experiment. Interpret usability data that indicates a potential problem with a product. List and discuss the fundamentals of Human-Computer Interaction and the application of those fundamentals to the design of a product.

Your Objectives Apply learning about usability to work products (security, plant operations, government contract, etc.) Weigh usability vs. investment and assess Be involved with “Next, Next” products and think out of the box Find proper place for usability in sw development cycle Discover difference between functionality, acceptability and usability Reduce complexity; find more pleasant user experiences

Usability Principles Learnability Memorability Efficiency Jakob Nielsen Technology needs to be tied to how users work (play, communicate) not just to what the work (game, message) is. (anonymous student, 2011)

Points in Interface Design/Development ...”people’s experiences with technology should be structured in accordance with their abilities of perception, cognition and movement (Cooper, et al., 2007)

Mental Models Mental Models: M of X M is a good model of X to the extent that it is useful in answering questions about X (Minsky, 1985) People understand and interact with systems and environments based on mental representations developed from experience (Lidwell, et al., 2003) p. 154

Interaction Design The What: “... you want to rigorously define the human and business needs that your product must satisfy.” (Cooper, et al., 2007) Goal directed “Why is a user performing an activity, task, action or operation in the first place?” (Cooper, et al., 2007)

Interaction Frameworks Cyclical (Heim, 2008, p. 42) Affordances (Norman, 1990)fundamental properties that determine just how a thing could possibly be used

Platforms for Interactive Devices Physical form, posture, display size, resolution, input method, connectivity, capacity, environment desktop, portable, handheld, web sites, web applications entertainment and educational systems Automobiles, Appliances, Robots, etc. Professional devices Kiosks

Postures for Interactive Devices Behavior of the program Sovereign (up and running continuously, e.g, word) Transient (comes and goes, invoked when needed, e.g., widgets) Daemonic (in background, e.g., printer driver)

Flow, Orchestration Follow user mental models Users direct Tools close Less is more Modeless feedback Design for probable Provide comparisons Provide graphical input/output Reflect object & app status Avoid unnecessary reporting, blank slates Provide choices Hide ejector seat levers Optimize for responsiveness Harmonious Interactions (Cooper, 2007, pp. 215-216)
