HUMAN COMPUTER INTERACTION
Study of Interaction between Human & Computer to Design Human-Centered Skills, So
that there are Principles & Methods to Create Excellent Interfaces with any Technology.
Interaction between Users & Computers occurs at the User Interface, which Includes both
Hardware & Software.
Interface is a point where the Human can Tell the Computer what to do.
5. CONT.
Human-Computer Interaction is a Discipline Concerned with the Design, Evaluation &
Implementation of Interactive Computing Systems for Human Use.
HCI is also Referred to as Man Machine Interaction.
• It is the HottestTopic among IT Professionals of Today.
• HCI would Play a Leading Role in the Creation of Tomorrow's Exciting New User
Interface Software.
7. The User Interacts Directly with Hardware for the Human Input & 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 & Output (I/O) Hardware.
Software & 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 theWorkflow.
WORKING:
9. • The Long History of User Interfaces Spans the Decades from the Primitive Punched-card
Days of the 1950s, through theTyped Command Lines of the 1960s, to the Familiar
Windows & Icons of Today & Beyond.
HISTORY:
10. ADVANTAGES:
• Changing Computers:- Internet, PC & Web Browser were Three Big Inventions of HCI
without these three ourToday would not have been Possible.
• The new Advances in HCI can be categorized in 3 sections wearable devices, wireless
devices, & virtual devices.
• Recent Advances of Research in HCI are in these areas:
➢Intelligent & Adaptive Interfaces
➢Ubiquitous Computing (UbiComp)
11. Intelligent & Adaptive Interfaces:
Intelligent HCI Designs are Interfaces that Incorporate at Least Some Kind of Intelligence in
Perception from &/or Response to Users:
Ex: Speech Enabled Interfaces that Use Natural Language to Interact with Users & Devices.
Adaptive HCI Designs, on the Other Hand, may not Use Intelligence in the Creation of Interface
but use it to Interact with Users.
Ex:A website using GUI for SellingVarious Products.
CONT.
12. Ubiquitous Computing:
The Idea of Ubiquitous Computing was to Embed Computers Everywhere in the
Environment & Everyday Objects so that People could Interact with many Computers.
CONT.
13. • It cannot work without Power/Voltage.
• It is more Expensive & Complex than other Methods.
• Requires the User to learn “Complex” Commands or Language.
• “Hidden Features i.e. if you don’t know the commands you won’t know
the features are there!
DISADVANTAGES:
14. • Quality of System Depends on How it is Represented & Used by User.
• Therefore, Enormous Amount of Attention has been Paid to Better Designs of HCI.
• Virtual Reality can be the Common Interface in Future.
• UbiComp is Trying to Embed theTechnology in the Environment & make it Invisible at
the Same Time.
• Natural & Neural Interfaces are the Future of Human-Computer Input Interfaces.
CONCLUSION:
