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.
