Human Computer Interaction Introduction

You will understand what is Human computer Interaction, what is User interface design, Job opportunities in HCI

2. What is HCI? HCI is the study of how humans can interact, with computer systems. Or HCI deals with the interaction and relationships between humans and computers .

3. HCI - History It was mainly popular from the late 70s to the early 90s . As a field of study It's a combination of computing science and behavioral psychology , and was mainly used to investigate how to make desktop computers more usable. Because in earlier time many never touched a computer.

4. .. Then in the 90s, the web was invented, and mobile phones and broadband internet both became widespread, and all that changed. In software fields , what used to be HCI is more widely known now as UX (user experience). In hardware fields such as robotics, virtual reality etc it tends to be called Human-machine interface(HMI) The combination of both Robotics and HCI is called Human –Robot Interaction(HRI)

5. Now HCI is moving in a new direction  Now, the pervasiveness of big data , new data collection  and interaction techniques is giving rise to a new but related discipline:  Human Data Interaction  (HDI) This is likely to be a field with major new opportunities for designers and analysts in the coming decades.

6. So if your some one who studied HCI Your more likely a user researcher Your someone who studies users motivations , barriers and circumstances to better understand how to solve their problems.  Your output generally takes the form of a report with some findings.

7. So if your someone claims you know UX Your closer to a interface designer. You take inputs from researchers , product managers , analysts , and the market to functionally solve the problems. Their output can vary from wireframes to fully functioning visual prototypes . Note : wireframes (an image or set of images which displays the functional elements of a website or page, typically used for planning a site's structure and functionality.

8. Difference between HCI & UX HCI is a field of study - you can do a Masters in HCI. UX is an application of the HCI theory. It is equal to Computer Science vs Software Engineer …….. One uses computer science theories to engineer a software.

9. After MS in HCI or Any Master degree in HCI Various job opportunities: 1. User Experience Researcher : identifies user wants/needs through a number of different qualitative and quantitative methods (e.g. interviews, querying user data logs).

10. … 2. Product Designer : goes from user needs to a product idea that addresses those needs. 3. Product Manager : takes a product idea, formulate its business potential outcomes and justification, and helps organize   the team of researchers, engineers, and designers to ensure that the execution of the idea still addresses the user needs. This is important because product idea changes often happen mid development.

11. …. Visual Designer : takes a product idea to physical form. Sketches, wireframes, and prototypes with tools like Figma /Sketch. User Interface Engineer or Software Engineer : works with visual designers to build their prototypes and wireframes into functioning code.
