CELLUON EVO MOUSE

ABSTRACT

The traditional mouse has certainly seen an evolution over the last ten years, moving from

the crud – collecting ball version with serial connections to laser – guided devices that plugs into

any USB port. Celluon now wants to take the evolution one step further by removing the hand –

held device altogether, turning your desk into a virtual touch screen. It is the new Evo Mouse

Pet, a dog – shaped device that functions differently and not like the other mouses.

The Evo Mouse pet is a device which sits at one side and gives access to the user to use

any surface close to like a touch pad. Here the user will no more have to carry the mouse and

move it in order to move the pointer on the screen. Now, the time has changed where all you

have to do is to move your finger on the surface and the pointer will move accordingly.

Basically, two lights emit from the device which track your finger and enables you to perform

your task just like a regular mouse.

Despite the conventional mouse, the functionality of this mouse is much simpler and

exciting. You don’t have to worry for the cursor control, dragging and double – clicking, right

and left clicking. This is the Evo Mouse developed by Celluon company to offer to the general

and business consumers an opportunity to enter in the multi touch world. This new mouse

enables you to rotate and zoom on images, scrolls the text to read and is done through gestures.

So, things have become more convenient. The design of this device is the shape of the dog,

which is why it is named as “PET”.

1. HISTORY OF COMPUTER MOUSE

1.1 EARLY MOUSE

The first functional mouse was actually demonstrated by Douglas Engelbart, a researcher

from the Stanford Research Institute, back in 1963. The respective peripheral was far away from

what we know today as “mice,” given the fact that it was manufactured from wood and featured

two gear-wheels perpendicular to each other, the rotation of each single wheel translating into

motion along one of the respective axis.

It’s not exactly very clear where the name “mouse” originates, since, apparently, the

name came from the fact that the device had a “tail” behind it, connecting it to a computer and a

display and was the idea of Bill English, a colleague of Douglas Engelbart’s and the person who

actually built the prototype device.

Engelbart's product was not the first pointing device, though. In fact, it seems that the

first such product, the trackball, was invented a lot earlier, namely at some point in 1953, by

Tom Cranston, Fred Longstaff and Kenyon Taylor from the Royal Canadian Navy, as part of the

secret military project DATAR. The name “trackball” comes from the fact that the respective

device actually used a standard Canadian five-pin bowling ball.

1.2 MECHANICAL MOUSE

German company Telefunken published on their early ball mouse, called "Rollkugel"

(German for "rolling ball"), on October 2, 1968. Telefunken's mouse was then sold commercially

as optional equipment for their TR - 440 computers, which was first marketed in 1968.

Telefunken did not apply for a patent on their device. Bill English, builder of Engelbart's original

mouse, created a ball mouse in 1972 while working for Xerox PARC. It is also called as Roller

ball mouse.

The ball mouse replaced the external wheels with a single ball that could rotate in any

direction. It came as part of the hardware package of the Xerox Alto computer.

Perpendicular chopper wheels housed inside the mouse's body chopped beams of light on the

way to light sensors, thus detecting in their turn the motion of the ball. This variant of the mouse

resembled an inverted trackball and became the predominant form used with personal

computers throughout the 1980s and 1990s. The Xerox PARC group also settled on the modern

technique of using both hands to type on a full-size keyboard and grabbing the mouse when

required.

Fig. Mechanical mouse, shown with the top cover removed.

The ball mouse has two freely rotating rollers. They are located 90 degrees apart. One

roller detects the forward – backward motion of the mouse and other the left – right motion.

Opposite the two rollers is a third one (white, in the photo, at 45 degrees) that is spring - loaded

to push the ball against the other two rollers. Each roller is on the same shaft as an encoder wheel

that has slotted edges; the slots interrupt infrared light beams to generate electrical pulses that

represent wheel movement. Each wheel's disc, however, has a pair of light beams, located so that

a given beam becomes interrupted, or again starts to pass light freely, when the other beam of the

pair is about halfway between changes.

Simple logic circuits interpret the relative timing to indicate which direction the wheel is

rotating. This incremental rotary encoder scheme is sometimes called quadrature encoding of the

wheel rotation, as the two optical sensor produce signals that are in approximately quadrature

phase. The mouse sends these signals to the computer system via the mouse cable, directly as

logic signals in very old mice such as the Xerox mice, and via a data-formatting IC in modern

mice. The driver software in the system converts the signals into motion of the mouse cursor

along X and Y axes on the computer screen.

The ball is mostly steel, with a precision spherical rubber surface. The weight of the ball,

given an appropriate working surface under the mouse, provides a reliable grip so the mouse's

movement is transmitted accurately.

2. X and Y rollers grip the ball and transfer movement

3. Optical encoding disks include light holes.

4. Infrared LEDs shine through the disks.

5. Sensors gather light pulses to convert to X and Y vectors.

1.3 OPTICAL MOUSE

Optical mice make use of one or more light-emitting diodes (LEDs) and an imaging

array of photodiodes to detect movement relative to the underlying surface, rather than internal

moving parts as does a mechanical mouse. A laser mouse is an optical mouse that uses coherent

(laser) light.

The earliest optical mice detected movement on pre-printed mouse pad surfaces, whereas

the modern optical mouse works on most opaque surfaces; it is unable to detect movement on

specular surfaces like glass. Laser diodes are also used for better resolution and precision.

Battery powered, wireless optical mice flash the LED intermittently to save power, and only

glow steadily when movement is detected.

Often called "air mice" since they do not require a surface to operate. It uses a tuning

fork or other accelerometer to detect rotary movement for every axis supported. The most

common models (manufactured by Logitech and Gyration) work using 2 degrees of rotational

freedom and are insensitive to spatial translation. The user requires only small wrist rotations to

move the cursor.

Usually cordless, they often have a switch to deactivate the movement circuitry between

use, allowing the user freedom of movement without affecting the cursor position. A patent for

an inertial mouse claims that such mice consume less power than optically based mice, and offer

increased sensitivity, reduced weight and increased ease-of-use. In combination with a wireless

keyboard an inertial mouse can offer alternative ergonomic arrangements which do not require a

flat work surface, potentially alleviating some types of repetitive motion injuries related to

workstation posture.

1.4 LASER MOUSE

The laser mouse uses an infrared laser diode instead of a LED to illuminate the surface

beneath their sensor. As early as 1998, Sun Microsystems provided a laser mouse with their Sun

SPARC station servers and workstations. However, laser mice did not enter the mainstream

market until 2004, when Paul Machine at Logitech, in partnership with Agilent Technologies,

introduced its MX 1000 laser mouse. This mouse uses a small infrared laser instead of a LED

and has significantly increased the resolution of the image taken by the mouse. The laser enables

around 20 times more surface tracking power to the surface features used for navigation

compared to conventional optical mice.

Fig. Laser mouse

Glass laser (or Glaser) mice have the same capability of a laser mouse but can also be

used on top of mirror or transparent glass with few problems.

In August 2009, Logitech introduced mice with two lasers, to track on glass and glossy

surfaces better. These mice are considered as effective, sensitive and accurate devices as they

support better tracking ability. With its user – friendly interface, this mouse is used by those

users, who perform highly skilled jobs. One of the positive outcomes of this mouse is its energy

efficient component that consumes lesser electricity when in use.

1.5 GYROSCOPIC MOUSE

There are a number of computer pointing devices (in effect a mouse) on the market that

have gyroscopes inside them allowing you to control the mouse cursor while the device is in the

air!  They are also wireless so are perfect for presentations when the speaker is moving around

the room. The gyroscope inside tracks the movements of your hand and translates them to cursor

movements.

Fig. Gyroscopic mouse

1.6 3D MOUSE

Also known as bats, flying mice, or wands, these devices generally function through

ultrasound and provide at least three degrees of freedom. Probably the best known example

would be 3D connexion / Logitech's Space Mouse from the early 1990s. In the late 1990s,

Kantek introduced the 3D Ring Mouse. This wireless mouse was worn on a ring around a finger,

which enabled the thumb to access three buttons. The mouse was tracked in three dimensions by

a base station. Despite a certain appeal, it was finally discontinued because it did not provide

sufficient resolution.

A recent consumer 3D pointing device is the  Wii Remote. While primarily a motion-

sensing device (that is, it can determine its orientation and direction of movement), Wii Remote

can also detect its spatial position by comparing the distance and position of the lights from

the IR emitter using its integrated IR camera. The obvious drawback to this approach is that it

can only produce spatial coordinates while its camera can see the sensor bar.

A mouse-related controller called the Space Ball  has a ball placed above the work

surface that can easily be gripped. With spring-loaded centering, it sends both translational as

well as angular displacements on all six axes, in both directions for each. In November 2010 a

German Company called Axsotic introduced a new concept of 3D mouse called 3D Spheric

Mouse. This new concept of a true six degree-of-freedom input device uses a ball to rotate in 3

axes without any limitations.

2. EVO MOUSE

2.1 INTRODUCTION

The Evo Mouse is the evolution of the computer mouse. It is the latest and portable

device which is the most cutting version of the mouse today. Evo Mouse is a dog – shaped

device that a dog-shaped device that functions differently and not like the other mice. It turns any

surface into a touchpad. With the Evo Mouse, you can perform common mouse operations by

using only your fingers. It works on nearly any flat surface and requires very little space. It

tracks effortlessly to your comfortable and natural movements.

The Celluon Evo Mouse is easy and convenient to set up and use. It can connect

wirelessly via Bluetooth or by using standard USB port with any device like smart phones,

tablets, laptops, computers, etc. It works with almost any desktop or laptop computer. The Evo

Mouse changes the way to interact with the computer by allowing you to use natural hand

movements and gestures in order to control the on – screen cursor.

2.2 TECHNOLOGY USED

In the Celluon Evo Mouse device, the technology is basically made up of two principle

components:

3D Electronic Perception Sensor Chips

Image Processing Software

2.2.1 3D Electronic Perception Technology:

Electronic Perception Technology (EPT) is a low cost, single chip imagining technology

that enables electronic components to form a 3D map of their surroundings and see what their

users are doing. One of the first applications is “Virtual keyboard”, a system that projects a laser

keyboard onto a table and detects which keys the user is pressing by watching their hands and

sensing which spots on the table their fingers are touching.

By sending out pulses of light and timing how long it takes for the reflection to return to

the sensor, EPT systems can determine depth. EPT systems can accurately determine brightness

and distinguish objects from one another.

Fig. Example of EPT

2.2.2 Image Processing:

 Image Processing is any form of signal processing for which the input is an image, such

as a photograph or video frame; the output of an image processing may be either an image or a

set of characteristics or parameters related to an image. Most image processing techniques

involve treating an image as a two – dimensional signal and applying standard signal processing

techniques to it. Image processing usually refers to the digital image processing, but optical and

analog image processing are also possible.

Fig. Image Processing

3. HOW IT WORKS ...?

The Evo Mouse pet looks like a small box with legs, almost like a crouching animal. It

turns any flat surface into a virtual track pad with your finger as the pointer and there is no more

pushing around a physical mouse. It sits right at the position where you would usually place a

mouse and through its two infrared sensors that look like eyes, it allows the usual mouse

functions. The two lasers coming out of this device track your fingers or pen which you use as

mouse on the surface.

Using the similar technology to projected laser keyboards, the Evo Mouse lets you move

your on-screen cursor without the use of a mouse. Just drag your finger over the area of projected

light to move the cursor where you want it to be. However, just like the conventional mouse, this

mouse functions. For instance, tap once with your finger which indicates a click, double tapping

means double clicking, next finger tapping means right click and double finger tapping at once

and dragging means scrolling the page. The Evo Mouse also features multi-touch functionality

including scroll, rotate and zoom, forward and back. The Evo Mouse can even be used for

handwriting recognition with your finger or a pen.

4. PRINCIPLE AND COMPONENTS

The basic principles of EVO mouse:

Celluon use the "TIME OF FLIGHT" principle to detect the motion of object.

Basic components of this technology:

IR pulse emitter - you can see the rectangle at the bottom. 

IR TOF CMOS sensor:

On the head of the cute shape between the two LEDs.

(LEDs here are indicators of system in operation, not for TOF function.)
