10 © HUMAN COMPUTER INTERACTION an academic discipline – The study of interactions between people (users) and computers a design discipline – designing interventions for systems involving people & technology

11 © HUMAN COMPUTER INTERACTION Human  End-user of the program – User Satisfaction is paramount Scrap Dealers example  Two or more users (friends,collaborators,co-workers ) Computers  Program that runs on the machine  Collection of servers (DB, Application, etc) Interaction  User tells computer what they want done  Computer communicates results

12 © USER INTERFACES(UI) Part of the application that allows  People to interact with computer  Computer to communicate results Can include hardware design  Buttons, sliders and other sensors HCI= DESIGNING, prototyping, implementation and evaluation of UI’s

13 © MACHINE (Techniques in computer graphics, operating systems, programming languages, and development environments are relevant) HUMAN (Communication theory, graphic and industrial design disciplines, linguistics, social sciences, cognitive psychology, social psychology, and human factors such as computer user satisfaction are relevant) ENGINEERING AND DESIGN METHODS INTERDISCPLINARY FIELD WITH 3 PRIMARY STRENGTH

14 © HCI ALLOWS ONE TO BE ONE OF THESE PERSONAS AT ANY GIVEN TIME Artist - We need to build systems that works We need to get the fit between engineering and peoples need (UR) 1.Design 2.Carry out 3.Analyze 4.Experiment You need to care about the beauty to the user Engineer - Designer Scientist

15 © PROCESS THAT GOES INTO USER INTERFACE DESIGN WHAT SHOULD WE CREATE? SOMETHING YOU CAN TEST QA

 Observe existing practices (due to no idea - IHS)  Create scenarios of actual use  Build models to gain insight into work processes 16 © UNDERSTANDING USERS (DESIGN) – DETAILS OF ITR

 Rapidly build a replica of your UI  Low fidelity techniques: Paper prototyping Video prototyping – without any single code (Photoshop)  High fidelity techniques: Interactive prototyping: (HTML, JavaScript, Flas h) – code development  Reason for prototyping is because we don’t want to get locked in implementation – spend much time here 17 © PROTOTYPING INTERFACES

Formative  Are we building the right thing?  What should be different in the next iteration? Summative  Does it work? Is it better than the existing solutions?  Can this teach us something about how people or the world work? 18 © EVALUATION - QA
