Human Computer Interaction Nizamae Campong
ICS3U-03 Table of Contents Introduction
Trip back in Time
Categories of HCI User Activity
HCI Design Process
Impacts on Society, Culture & Economy
Recent Advancements in HCI
What the Future Holds What is HCL? a study about how people interact with computers study of how far computer development will go. HCI Design Process How are successful technology made? Impacts Society User-friendly Culture Economy convenient
wide variety of choices
personal judgement
Touch Screen used in mobile phones and portable computers

easier input as the user touch the icons, press to choose options Gaming has evolved to the point where users do not need joysticks, handles, remote controls Kinect full body motion sensor (Xbox 360) surpassed and change video home gaming Statistic: Followed by the Christmas holiday in 2012, there were a combine sales of 800 million units Mobile Phones major breakthrough in portable communications technology
first release, business world used, and was the size of a brick developed and innovated
compact size
better features (smartphones) Specialized Interfaces widely available to people with disabilities Disadvantages Deskilling People lean on computers
Lesser intelligence Sociological impact weak literacy and social skills Repeated cycle = new generation = less intelligent Benefits More people are connected
Interaction between cultures and interaction Mobile networks in Africa small tribes scattered across continent Slight increase of wealth and income Productivity to individuals and the company efficient contributor to society
increases output for the company, able to work with more businesses. Portable communication invention of gadgets, communication anywhere past: workers had to go to workplace to do work present: Stay-at-home, work anywhere
Stay on task effectively Negative Effects more automated machines, less need for employees massive job unemployment > lower economy Millions of outdated technology and e-waste each year developing countries Recent Advances in HCI GOAL: provide easier
user-friendly experience SixthSense created by Pranax Mistry of MIT Media Lab's Fluid Interfaces Group Wearable gestural interface Create. Be imaginable Ultrasonic pen Infrared camera attached to laptop tracks your handmotion phone dial pad on palm
take pictures Emotiv created by Tan Le allows control over electronic systems

lets users move objects on a computer screen with the power of THOUGHT Demos:
Wheelchair controlled by man with the headset
Lift virtual box after training session GPS Navigation Systems specify a specific location
helped navigation on Earth Method

former methods of interaction + advancing technologies = better technology for humans. Devices
virtual Military Devices: thermal vision
RFID radio frequency identification products
PDA assistants Canesta Keyboard made by Compaq specifically designed for iPAQ
virtual keyboard, projects QWERTY keyboard
Finger movements tracked by motion sensor and send input to device's screen. HCI User Activity 3 types: physical
affective 3 human senses Vision switch bases
pointing devices Audition speech recognition
beeps, alarms, commands of GPS Touch haptic devices (skin and muscle sensors)
made for virtual reality or disability and assistive applications Trip back in Time PUNCH CARDS 1800 control looms
IBM initially used by 1900s
fail of usage 1873 Christopher Scholes
invented the QWERTY layout TRACKBALL 1952 Canadian-made
secret military project
belonged to Canadian Royal Navy. ATARI 2600 1900 APPLE LISA MOUSE 1963 NINTENDO WII 2006 LAPTOPS What the Future Holds Interactive 3D projection projected from a portable surface
physical contact, gestures, and speech interaction users can touch icons
body gestures can be recognized by a camera
speech recognition application IMPACTS
maximize interaction between human and computer
no need of devices
user-friendly to disabled people
increased economic growh
easier work In the future: intuitive
easier to use BENEFITS: humans exert less activity
dependent on computers
trust computers in lives
socially connected DISADVANTAGES: high technology change may confuse users
difficult to use, replaces hardware tech (mouse) -> software
changes job skill
expensive to produce such technology
power consumption
too expensive to buy cognitive planning DESIGN PROCESS References http://searchcio-midmarket.techtarget.com/definition/HCI
