Human-computer interaction has evolved significantly from the early use of punched cards and command line interfaces to modern graphical user interfaces, touchscreens, and gesture-based interaction. Key developments included the first mouse in 1963; the Apple Lisa personal computer with a GUI in 1983; multi-touch screens in 1984; and technologies like Microsoft's Kinect and intelligent personal assistants that support natural user interfaces using gestures, speech, and touch. Virtual and augmented reality now provide immersive, simulated experiences through head-mounted displays and other sensory technologies. User experience design draws from fields like psychology, software engineering, and human factors to optimize interfaces for usability.
Human Computer Interacton
- 1. Human Computer Interaction HCI Then & Now
- 2. Analytical Engine Charles Babbage - 1837
- 3. Punched Cards (1950) • According to IBM punched card became the basic I/O methodology for computers. • 18th century used for textile looms. • 19th century used for enter data in to tabulate machine. .
- 4. Light Pen (1951) • A device that senses the change of the brightness of the screen. • Whirlwind was the first computer, which used this revolutionary new device .
- 5. Command Line Interface • Teletype keyboard help to input the command through the command line. • Later cathode ray tube use to display the commands.
- 6. Computer Mouse (1963) • First mouse was developed in 1963. Only one button with wooden block. • 1972 mouse developed with two roller wheals with metal balls. • 1980 made the special mouse pads and utilize sensors to detect light and dark.
- 7. Before 1960 • There was no focus on HCI • Focus was on computations rather than presenting it attractively. • Graphical and gestural user interfaces (Sutherland 1963), • Synchronous collaboration through direct pointing and shared windows (Engelbart and English 1968)
- 8. Apple Lisa (1983) First Personal Computer with GUI
- 9. Multi touch (1984) • First transparent multi touch screen overlay was build on 1984. • Surface of voltage applied across it and touch sensors laid above the CRT display
- 10. Factors led to HCI development after 1980s 1. Prototyping and Iterative Development 2. Software Psychology and Human Factors 3. New User Interface Software 4. Models, Theories, and Frameworks
- 11. UI to UX User Experience
- 12. The modern HCI principles
- 13. Methodologies of HCI Design • Activity Theory • User Centered Design • Principles of UI design • Value sensitive design (VSD)
- 14. Responsive Web designs • Responsive web design (RWD) is an approach to web design aimed at crafting sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices
- 15. Gesture Recognition • Gesture recognition involves determining the movement of a user’s fingers, hands, arms, head or body in three dimensions through the use of a camera; or via a device with embedded sensors that may be worn, held or body-mounted. • The primary application for gestural interfaces at present is in the gaming and home • entertainment market. • potential of hands-free control of devices • Ability for several people to interact with large datasets.
- 16. Kinect Technology • Kinect is a line of motion sensing input devices by Microsoft • Came with Xbox 360 and Xbox One video game consoles and Windows PCs. • Based around a webcam-style add-on peripheral, it enables users to control and interact with their console/computer without the need for a game controller, through a natural user interface using gestures and spoken commands
- 17. Multi touch Devices • Provides a realistic User Experience • Became popular with handheld devices • Still have some drawbacks when adopting for critical systems.
- 18. Intelligent Personal Assistants • Siri by Apple Inc. • Cortana by Microsoft • Speech recognition • Natural language processing • Knowledge management
- 19. Virtual Reality Microsoft developing VR applications
- 20. Virtual Reality • Virtual Reality sometimes referred to as immersive multimedia, is a computer-simulated environment that can simulate physical presence in places in the real world or imagined worlds. Virtual reality can recreate sensory experiences, which include virtual taste, sight, smell, sound & touch
- 21. Devices Used in a VR system • Head Mounted Displays • Head Trackers • Motion Trackers • Data Gloves • 3D Controllers • Haptic Devices • Stereoscopic 3D Displays • VR Domes.
- 22. Advantages of VR • Real life simulations • Cost effective • Safe environments • More practical than a theoretical lesson • Real life situations
- 23. Disadvantages of VR • Cost • Uncomfortable devices • Communication problems
- 25. Augmented Reality • Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data.
- 26. Advantages of AR • Mobility • Wear ability • Hands free • Multi model (google Glass)

Editor's Notes
- #9: Xerox star 8010 was the first commercial computer system with GUI and Mouse.
- #12: Till 1970s computers only for technicians User interface is not the only user experience
- #13: The user interacts directly with hardware for the human input and output such as displays, e.g. through a graphical user interface. The user interacts with the computer over this software interface using the given input and output (I/O) hardware. Software and hardware must be matched, so that the processing of the user input is fast enough, the latency of the computer output is not disruptive to the workflow.
- #15: Social networks – Facebook/twitter Wide range of mobile devices
- #28: Using layar app for the AR
