Surface Computing &

DevicesBy : Sheeyam Shellvacumar

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 Direct Interaction - Hands interacting with touch/Physical gestures Multi-Touch - Recognize multiple points of contact at the same time Multi-User

- Allowing a collaborative computing experience Physical Object Recognition

- Retrieve digital content from physical objects

Microsoft PixelSense 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

The Design 1-Screen

2-Near IR light source

3-Near IR camera

4-Projector

5-CPU

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

display

The picture is analyzed using image processing techniques

The output is sent to the PC. It includes the corrected sensor image and various

contact types.

Surface Computing Applications

Surface Computing Applications

AFTER-MOUSE Paint-Touch

AFTER-MOUSE Presentation-Touch

AFTER-MOUSE Map-Touch

Application Development

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

administrator tools

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

Advantages 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

Disadvantages Surface computers are very expensive and doesn’t fit with

household usage.

For now it only fits to enterprise context.

Microsoft’s pixel-sense based surface computer cost around

12,500 USD

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

countertop.

Educational environment, where university students could

assemble and disassemble quickly and easily.
