A huge variety of e-services are available today. Besides functionality, they are expected to enable users to interact with them accurately, efficiently, and with a reasonable level of satisfaction.Hence, a principal goal of the course is for students to develop an awareness and sensitivity for user needs and abilities as they interact with computer applications,websites and other interactive devices. Students will be introduced to basic aspects of human behavior that influence the design, development, and use of new e-services in order to: articulate the cost and consequences of ineffective e-services design to users, organizations and society; articulate psychological theories explaining human capabilities and limits as they apply them to e-services design; identify usability and accessibility issues for diverse user populations; analyze and specify the goals and needs of users; observe users interacting with e-services and diagnose problems using theoretical constructs; plan, prototype, evaluate, and document the user-centered rationale for an e-services design project
