Advances in Human / Computer Interaction technology are transforming the way we interact with our computing devices

7

“From brain-controlled machines to gesture-driven devices, there's a range of technologies in development that may find their way into everyday electronic devices.” – IDG News

“For decades our options for interacting with the digital world have been limited to keyboards, mice, and joysticks. Now with a new generation of exciting new interfaces in the pipeline our interaction with the digital world will be forever changed” – SingularityHub

Gartner: Interface Types

Gartner

“Why do we still use a keyboard and mouse to interact with digital information? This mode of human-computer interaction, invented more than 40 years ago, severely constrains our ability to access and interact naturally with digital content..” – MIT Media Lab


Apple’s iPad Multi-touch capability has already changed the way we expect to interact with computers in the future.

8

“The iPad has created a transformational change in how people interact with computers. Multitouch on the iPad and other media tablets has liberated users from the hardware keyboard and pointing device (aka the mouse). As media tablets become more commonplace, users will expect the convenience and simplicity of multitouch user interfaces when they interact with other computing devices” – Gartner

Multitouch


...and Apple Siri and MS Kinect are paving the way for a whole new way of interacting with our computers.

9

“I’m convinced this (Kinect) is a transformational technology. With NUI, computing devices will adapt to our needs and preferences for the first time and humans will begin to use technology in whatever way is most comfortable and natural for us” – Bill

Gates

http://www.youtube.com/watch?v=diy7rkWkDtU http://www.apple.com/iphone/videos/#tv-ads-siri

“An intelligent assistant that helps you get things done just by asking. Siri understands context allowing you to speak naturally when you ask it questions” – Apple Press Release

Kinect

Siri


Mobile Computing will impact all business processes, requiring new application solutions written just for mobile

10

“Mobile business is the number one IT issue pre-occupying the minds of IT professionals in Asia/Pacific, according to IDC's CIO Innovation Survey 2011. ” – IDC

“Second generation mobile strategies differ considerably from those of the first generation. They must be multichannel, part of your holistic digital strategy, and include innovative mobile-only capabilities.” – Gartner

IBM 2011 Tech Trends Report

“By 2015, mobile Web technologies will have advanced sufficiently, so that half the applications that would be written as native apps in 2011 will instead be delivered as Web apps. ” – Gartner

Cloud Computing Definition

Cloud computing is a new consumption and delivery model inspired by consumer internet services and driven by client needs

Cloud computing has 5 key characteristics:

1. “Always on” network access 2. On-demand self-service 3. Location independent resource pooling4. Rapid elasticity – grow & shrink easily5. Flexible pricing models

SaaS is a delivery model in which a commercial vendor develops the software, hosts its operation, and provides customers access to it over the Internet

• The SaaS provider delivers a complete, usable, finished application complete with user support on a pay-for-use or subscription basis. Enterprise data import/export and management is achieved with an API or an administration console.

• SaaS applications can generally be configured, but not customized. The changes that a company can make to a SaaS application are only those envisioned and enabled by the SaaS vendor.

Base: North American and European IT services decision-makers from enterprises with 1,000 employees or more who have adopted each “as-a-service” offering/approach (where 161 and 397, respectively, are the smallest and largest sample sizes of the group) (percentages may not total 100 because of rounding)
