What is Surface Computing?
Surface computing is a multi-touch technology that allows users
to handle digital contents using natural motions using hands and
physical things on a flat surface
Surface computing is a new approach of working with computer
that replaces the traditional mouse & keyboard experience.
NUI (Natural User Interface) used in surface computing help
interaction with digital contents in the way how they interact with
physical objects with hand gestures
Features of Surface Computing
- Hands interacting with touch/Physical gestures
- Recognize multiple points of contact at the same time
- Allowing a collaborative computing experience
Physical Object Recognition
- Retrieve digital content from physical objects
Long time research of Microsoft for more than 12 years which
started on 2001
An NUI with a combination of hardware and software
Hardware support given by Samsung
2-Near IR light source
3-Near IR camera
How does this work?
A contact is placed on the display
IR back light unit provides light that hits the contact.
Light reflected back from the contact is seen by the integrated sensors
Sensors convert the light signal into an electrical signal/value
Values reported from all of the sensors are used to create a picture of what is on
The picture is analyzed using image processing techniques
The output is sent to the PC. It includes the corrected sensor image and various
Applications for the Microsoft PixelSense are built using the
Microsoft Surface 2.0 SDK
The Microsoft Surface 2.0 SDK builds upon:
Embedded Windows 7 Professional 64-bit
.NET Framework 4.0
Windows Presentation Foundation (WPF) 4.0
Microsoft XNA® Framework 4.0
Windows PowerShell and DMTF DASH support, and enhanced
Second Light Technology
Microsoft's Second-Light is a new technology in the works
from Microsoft Research.
Second Light technology allows users to slide "magic lenses"
over the display to provide a second surface that can be
linked to the first
Works as an interface between human natural gestures and
high tech hardware components
Detect physical objects using its cameras
No need wires or USB Ports to connect devices
Processes are done in a natural way using an NUI so that
the time is saved
Surface computers are very expensive and doesn’t fit with
For now it only fits to enterprise context.
Microsoft’s pixel-sense based surface computer cost around
Surface application cost around 2000-3000 USD.
Privacy of data of users is lost.
Future of Surface Computing
Brand new experience for the PC , laptop & tablet users
Surface Computing become more mingled with people’s
lifestyle and variety of environments
It will be used in schools, businesses, homes as a part of the
Educational environment, where university students could
assemble and disassemble quickly and easily.
