This document discusses human-computer interaction (HCI), which involves studying how users interact with computers. HCI aims to design interfaces that allow intuitive interaction. The document outlines the history of HCI technology from the 1950s onward and discusses recent advancements in interaction methods, like gesture recognition and virtual controllers. It also notes some challenges in developing technologies that flexibly support natural human behaviors.

3.  This article is about the interaction between
users and computers. For the direct
communication between brain cells and
computers
 Human–computer Interaction (HCI) involves the
study, planning, and design of the interaction
between people (users) and computers
 Interaction between users and computers occurs
at the user interface (or simply interface), which
includes both software and hardware

4.  HCI has to do with the space that is created
for you to work with technology.
 That space is what you become “submerged”
in when you interact with a computer
 HCI (human-computer interaction) is the
study of how people interact with computers
and to what extent computers are or are not
developed for successful interaction with
human beings

5.  The article, “A Brief History of Human-Computer
Interaction Technology” is a brief description of the
history of HCI technology from 1950s to 1990s.
 Recently, HCI technology has been rapidly developed
and diversified, so it seems that we are trying to
interact with almost every object around us in a way
that wasn’t possible before.
 These technologies include Hypertext and
Multimedia; the ways to input information with
machines, like mouse, tablet, and motion sensing
device and effective.

6.  Sign language recognition
 For socially assistive robotics
 Directional indication through pointing
 Control through facial gestures
 Alternative computer interfaces
 Virtual controllers
 Remote control

7.  Sometimes called as Man-Machine
Interaction.
 Interaction (HCI) follows technologies like
hypertext &multimedia.
 HCI design should consider many aspects of
human behaviors and needs to be useful

8.  Identification
 Latency
 Resolution
 Stability
 User friendly

9.  Inflexible.
 Does not take responsibility.

10.  HCI promises to allow users to interact with
computers in much the same way that they
interact with the physical world.
 The aim is to make the computers more
friendly &easy to use for the user.
