This document presents information on touch technology and multi-touch interfaces. It discusses the history of touchscreens and how multi-touch improved on traditional keypads. Major companies that adopted multi-touch include Apple, Microsoft, Dell, Google and HP. Multi-touch offers advantages like more intuitive gestures over menus and is now common in smartphones, tablets and other devices. While powerful, multi-touch interfaces also face limitations such as difficulty with small selections and lower battery life. Overall, the document examines the rise of multi-touch technology and its impact on business applications.

2. Outline
 Touch technology
 Multi-touch
 Problems of traditional keypad
 Advantages of multi-touch
 Companies benefited using multi-touch technology
 Business value of multi-touch
 Limitations of touch technology
 Case study questions & answers

3. 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

4. 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. . .

5. 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)

6. 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.

7. What is ‘new’ to the touch?
 New in mobile market
• Introduced into the market through
Apple’s iPhone (2007)
 Replaces traditional keypads

8. 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

9. Motivation behind Apple’s multi-touch
Control everything using only your fingers

10. Other companies adopted multi-touch
 Microsoft
 Dell
 Google
 HP

11. Windows Touch
 Browse online newspapers
 flick through photo albums
 shuffle files and folders
—using nothing but your fingers.

12. Dell Latitude XT tablet PC
Helpful to people who can’t grasp
a mouse

13. Android’s multi-touch
 Native support for multi-touch

14. 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)

15. 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

16. 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

17. 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

18. 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)

19. 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

20. 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

21. 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

22. 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

23. 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

24. 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

25. 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

26. 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
