THE EVOLUTION OF HUMAN COMPUTER INTERACTION PAST PRESENT

THE EVOLUTION OF HUMAN COMPUTER INTERACTION PAST, PRESENT AND FUTURE

PAST Challen ges - Focus on functionality - Not user friendly, complex - Not intuitive - Less interactivity People - User have to be technically well trained so that can be able to use the product effectively

PAST 1943 – ENIAC, the world's first all electronic numerical integrator and computer. 1944 - The Mark I paper tape readers. 1948 – IBM SSEC was an electromechanical computer built by IBM

PAS T 1963 - Sketchpad 1983 - Apple Lisa 1984 - Apple Macintosh

Present Input - Keyboard Cursor key Mouse Microphone Touch pad on laptop - Touch screen Outp ut - Scrolling glass teletype - Character terminal - Bit mapped screen - Audio

Prese nt Social Impact -Reduces human to social interaction (anti social) Challen ges - - Functionality should not be at expense of interactivity Have to maximize the potential of existing technology Some interactive HCI technology not mature enough, causing frustration of user. (Voice command, face recognition) People -younger generation is more comfortable with the HCI technology

Prese nt

Future Input - Holographic display - Computer jewelry - Data gloves and suits Outp ut - Head mounted display - Autonomou s agents

Future Challen ges People - - Security and privacy may not be economically effective - - Holography , gesture based HCI Artificial intelligence may be able for computers for better understand or interact with humans. Better voice recognition Neurology based (brain wave control
