What is a touch screen?
An electronic visual display
Locates the coordinates of a
user’s touch within display area
Works independently of what is
being displayed on screen
When is it Applicable?
Allows users to interact directly
with what is being displayed
Can be used without any
intermediate device
Found in modern smartphones,
video games, navigation
systems, etc. . .
Brief History
1965 : Invented by E.A. Johnson for air traffic control
1971 : Brought into public domain by Elographics, Inc.
1983 : HP-150 (personal touch screen computer) by Hewlett-Packard
1993 : Apple’s Newton and IBM’s Simon
2002 : Microsoft’s Windows XP Tablet
2007 : Apple’s iPhone (Multi-touch)
Multi-touch
Recognize the presence of two or more
points
Not new, Academic and commercial
researchers have been working on multi-
touch technology for years
Used in ATMs, airport kiosks etc.
What is ‘new’ to the touch?
New in mobile market
• Introduced into the market through
Apple’s iPhone (2007)
Replaces traditional keypads
Problems with traditional keypads
Complex UI with lots of menus and buttons
Need to remember the commands
Display must be used for single purpose at a time
Doesn’t support free hand applications
Less flexible
Difficult to adopt for new users
Not user friendly for old users
Not suitable for autistics
Windows Touch
Browse online newspapers
flick through photo albums
shuffle files and folders
—using nothing but your fingers.
HP’s touch smart
Lets you use two fingers at once to manipulate images on the
screen
Make on-screen gestures designating specific commands
without using cursors or scroll bars
Casual computing (For example: Putting on music while
preparing dinner)
Why is Multi-touch everywhere?
More versatile than single-touch interfaces
Allows to use one or more fingers to perform special gestures
Easier to remember than commands
Do not have to be learned
Display used as input device combine with GUI
Real-time interaction for users
Reduces buttons and menus ,making UI simpler
Improved flexibility of customization
Touch technology changes life
Helps an autistic
An easy-to-use computer for students in early grades
Ease of use for older User
Helpful to people who can’t grasp a mouse
Expected Fields
Customers might use touch to place orders with a retailer
Conduct virtual video service calls
Utilize social networking for business
Allows visitors to check out a virtual visitor’s Center
Video chats with remote workers through a built-in Webcam
Use microphone, access e-mail and the Internet, and manage contacts, calendar
items, and photos Without using keyboard and mouse
The revolution touch screen brings
iPhone users in U.S. had grown at a rate of 159 percent in August
2009 compared to past year with 23.8 million users [1]
58 percent of touchscreen mobile devices are expected to contribute
to the worldwide mobile devices sales by 2013 [2]
1. Report of Lipsman (2009)
2. Report of Pettey and Tudor (2010)
The revolution touch screen brings
Market size of touch screen mobile phone
2010 : $4.58 billion
2011 : $6.09 billion
2012 : $9.65 billion
Growth of touch screen mobile phone unit
2010 : 494 million units
2011 : 665 million units
2012 : 1.35 billion units
Limitations
not a realistic replacement for keyboard input
large display requirement
difficult to select small items
are not as accurate as traditional mouse and physical button-navigated applications
having a big bright screen and needing massive computing power to run this means a very low
battery life
in direct sunlight it is much less effective and most of the time very difficult to read the screen
if a touchscreen devise were to crash the whole screen would be unresponsive, and because of
the lack of buttons recovering it would be very difficult
Future of touch technology
It’s too early to know if the new multi-touch interface will ever be as
popular as the mouse-driven graphical user interface
But till today it is showing the positive signs
CASE STUDY QUESTIONS
What problems does multi-touch technology solve?
Helps people with disabilities
Replace the use of mouse and keyboard
Minimize complexity of UI
CASE STUDY QUESTIONS
What are the advantages and disadvantages of a multi-touch
interface?
Advantages
Extremely good for object manipulations
More versatile than single-touch interfaces
Multi touch gestures are easier to remember than commands
Collaborative use
CASE STUDY QUESTIONS
Disadvantages
Eyes on : Touch screen interfaces are nearly all “eyes on”. You cannot type by
touch while your eyes are occupied elsewhere
Hands on : Handheld devices that rely on touch screens for input require two
hands to operate: one to hold the device and the other to operate it.
Fingers on :Your finger is not transparent: the smaller the touch screen, the
more you obscure what is being pointed at
CASE STUDY QUESTIONS
Describe three business applications that would benefit from a
multi-touch interface.
Reading digital material (e-books/ e-mail)
Customers might use touch to place orders with a retailer
Video chats with remote workers through a built-in Webcam
CASE STUDY QUESTIONS
What management, organization, and technology issues must be
addressed if you or your business was considering systems and
computers with multi-touch interfaces?
Management : Cost, technology adoption, training, business objective
Organization : Structure and capability
Technology : Fast server, system ready for use, better
serve, permanent hardware
