MARKETING
1960’s – 2000’s
LOGITECH SOLD $618 MILLION WORTH OF
POINTING DEVICES IN 2011, JUST A FEW
MILLION SHORT OF 2008'S PEAK, AND UP
$90 MILLION FROM 2010. THOSE SALES
WERE MADE IN AN ENVIRONMENT WHEN
THE IPAD WAS THE HOTTEST ELECTRONICS
DEVICE AROUND. WHATEVER ROLE THE
MOUSE AND KEYBOARD PLAY IN OUR
FUTURE, ONE THING IS CERTAIN: THE
MORE WE DIGITIZE OUR LIVES, THE
GREATER NUMBER OF TOOLS WE'LL NEED
TO TALK WITH COMPUTERS -- WHETHER
MOUSE, KEYBOARD, OR TECHNOLOGY
STILL UNSEEN.
MARKET PERSPECTIVE
COMPUTER MICE ARE OFTEN MADE
FROM A COMBINATION OF MATERIALS,
NAMELY PLASTICS, RUBBER, WOOD
AND METAL. PLATICS SUCH AS P.E.T.,
A.B.S. AND ACRYLIC ARE COMMONLY
USED, BOTH OF THE THERMOPLASTIC
AND THERMOSETTING PLASTIC
VARIETY. CERTAIN MATERIALS SUCH AS
RUBBER AND LEATHER ARE USED FOR
THEIR GRIP, COMFORT, CONTROL AND
DURABILITY PROPERTIES.
MATERIALS
A COMPUTER MOUSE IS AN
INPUT DEVICE THAT IS MOST
OFTEN USED WITH A
PERSONAL COMPUTER.
MOVING A MOUSE ALONG A
FLAT SURFACE CAN MOVE THE
ON-SCREEN CURSOR TO
DIFFERENT ITEMS ON THE
SCREEN. ITEMS CAN BE
MOVED OR SELECTED BY
PRESSING THE MOUSE
BUTTONS
ERGONOMICS &
ANTHROPOMETRICS
A COMPUTER MOUSE DESIGN IS BASED ON A
NUMBER OF ERGONOMIC FACTORS, WHICH
RELATE TO OR ARE DESIGNED FOR EFFICIENCY AND
COMFORT IN THE WORKING ENVIRONMENT.
HUMAN ANTHROPOMETRIC MEASUREMENT IS AN
IMPORTANT INPUT FACTOR WITHIN THIS PROCESS
IN TERMS OF GUIDING DESIGN SHAPE AND SIZE.
REGARDING COMPUTER MOUSE DESIGN, HAND
COMFORT, POSITIONING AND MOVEMENT
COUPLED WITH FINGER CONTROL MOVEMENTS
INFORM A VARIETY OF SHAPES AND FUNCTIONAL
COMPONENTS ON COMPUTER MICE. SURFACE
PRESSURE, PALM COMFORT AND FINGER
MOVEMENT ARE ALL EMBEDDED THROUGH
ERGONOMIC AND ANTHROPOMETRIC
CONSIDERATIONS AS COMPUTER MICE INVOLVE
LONG REPITIVE USE AND THEREFORE MUST
SUPPORT THE USER. SPECFIC COMPUTER MICE
HAVE BEEN DEVELOPED FOR C.A.D. DRAWING AS
WELL AS ASSISTIVE TECHNOLOGY FOR FULLY AND
PARTIALLY DISABLED USERS.

PAGE
EXPLORATIONOFBRIEF
THERE ARE AT LEAST TWO PRIMARY
CONSIDERATIONS FOR ERGONOMICS:
PROTECTION FROM
INJURY/DISCOMFORT RISK FACTORS
FOR FORCE, POSTURE AND
REPETITION/FREQUENCY. DURATION
(OF INDIVIDUAL FORCE OR POSTURE
EVENTS; OF THE DAY) TO OPTIMIZE
PERFORMANCE AND
ACCURACY/PRECISION AND
COMFORT
FOREARM FLAT.
VERY COMMON AND EASY TO
PROCURE;
GENERALLY SIMPLE AND INEXPENSIVE;
SUITABLE FOR NON-INTENSIVE USE
AMONG HEALTHY POPULATIONS.
THE FOREARM REMAINS IN NEAR
EXTREME PRONATION DURING USE, A
POTENTIAL POSTURAL RISK FACTOR,
ESPECIALLY FOR HEAVY COMPUTER
USERS.
FOREARM ANGLED
REDUCES FOREARM PRONATION WHILE
MAINTAINING A SIMILAR EXPERIENCE TO
TRADITIONAL 􀂢AT DESIGNS ANGLED
FOREARM MICE ARE OFTEN, IF NOT
ALWAYS, DESIGNED FOR EITHER THE
LEFT OR RIGHT HAND, AND CANNOT BE
USED INTERCHANGEABLY BY EITHER
HAND. SOME MODELS ARE AVAILABLE IN
BOTH RIGHT AND LEFT HAND VERSIONS,
WHILE OTHERS ARE RIGHT HAND ONLY.
FOREARM VERTICAL
OFTEN TOUTED AS SUPPORTING A NATURAL "HANDSHAKE POSTURE," VERTICAL
MICE ENCOURAGE A MORE NEUTRAL FOREARM POSTURE. NON-TRADITIONAL
APPEARANCE AND USABILITY EXPERIENCE MAY BE REJECTED BY SOME USERS;
ARE OFTEN, IF NOT ALWAYS, DESIGNED FOR EITHER THE LEFT OR RIGHT HAND,
AND CANNOT BE USED INTERCHANGEABLY BY EITHER HAND; SOME MODELS
ARE AVAILABLE IN BOTH RIGHT AND LEFT HAND VERSIONS, WHILE OTHERS ARE
RIGHT HAND ONLY; OPERATION INVOLVES FULL-ARM MOVEMENT, WHICH MAY
AGGRAVATE SHOULDER DISORDERS, FOR EXAMPLE, AND MAY AFFECT
PRECISION FOR SOME USERS AND TASKS.
SPECIALIZED GRIPS
DEPENDING ON THE MODEL, SPECIALIZED GRIP DESIGNS ARE TYPICALLY
DESIGNED WITH A SPECIFIC UNDERLYING POSTURAL THEORY IN MIND, SUCH
AS RECREATING A PEN-LIKE GRIP FOR PRECISION TASKS, OR ENCOURAGING A
"POSITION OF FUNCTION" FOR THE HAND. NON TRADITIONAL APPEARANCE
AND USABILITY EXPERIENCE MAY BE REJECTED BY SOME USERS; SOME
SPECIALIZED GRIP DESIGNS, SUCH AS THOSE TOUTING PRECISION (E.G., THE
BOTTOM TWO EXAMPLES AT RIGHT), ARE MORE SUITABLE FOR SPECIFIC
PRECISION TASKS, AND MAY NOT NECESSARILY IMPROVE THE USER
EXPERIENCE FOR GENERAL COMPUTING TASKS.
CENTRED
ELIMINATES THE NEED TO REACH TO ONE SIDE
OR THE OTHER, REDUCING SHOULDER
LOADING; OFFERS FLEXIBILITY IN THE USE OF
DIFFERENT FINGERS/THUMB TO OPERATE.
NON-TRADITIONAL APPEARANCE AND
USABILITY EXPERIENCE MAY BE REJECTED BY
SOME USERS; SOME MODELS DON'T
INTEGRATE WELL WITH SHAPED OR SPLIT
KEYBOARDS; REQUIRES ADDITIONAL WORK
SURFACE SPACE.
TRACKBALL
DEPENDING ON THE MODEL, CAN
REDUCE CONCENTRATED FORCES BY
DISTRIBUTING OPERATIONS OVER
MORE THAN ONE FINGER; CAN
PROVIDE ENHANCED PRECISION. NON-
TRADITIONAL APPEARANCE AND
USABILITY EXPERIENCE MAY BE
REJECTED BY SOME USERS; SOME
MODELS CONCENTRATE LOADING
ONTO ONE FINGER/THUMB.
TOUCH PAD
INTRODUCED THE CONCEPT OF
FINGER/TOUCH INTERACTION;
MINIMIZES FORCE AT THE FINGERS
AND ELIMINATES GRIP
REQUIREMENTS. NON-TRADITIONAL
APPEARANCE AND USABILITY
EXPERIENCE MAY BE REJECTED BY
SOME USERS; THIS TECHNOLOGY IS
BEING REPLACED BY TECHNOLOGY
IMPROVEMENTS THAT SUPPORT
TOUCH SURFACE / GESTURING.
TOUCH SURFACE
REDUCES OR ELIMINATES THE NEED TO
GRIP; MINIMIZES FORCES; PROVIDES
VARIABLE POSTURE SUPPORT; MAY
PROVIDE NEW FUNCTIONALITY (E.G.,
MULTIPLE FINGER SWIPING
PROTOCOLS). NON-TRADITIONAL
USABILITY EXPERIENCE MAY BE
REJECTED BY SOME USERS; SOME
USERS EXPERIENCE HIGH ERROR RATES,
ESPECIALLY WHILE LEARNING THE
SWIPING PROTOCOLS.
PEN OR STYLUS
DESIGNED TO EMULATE THE
POSTURE USED IN WRITING TASKS;
DEPENDING ON THE MODEL, CAN
BE GOOD FOR PRECISION TASKS.
CAN RESULT IN CONTACT STRESS
POINTS ON THE SIDE OR BASE OF
THE HAND; LIKE WRITING, CAN
RESULT IN HIGH PINCH GRIP
FORCES.
FOOT CONTROLLED
ELIMINATES THE HAND(S) FROM MOUSE
TASKS; HAS APPLICATIONS BEYOND
TYPICAL COMPUTER INPUTS (E.G.,
MUSICIANS THAT NEED TO OPERATE
COMPUTERS / SWITCHES WHILE
PERFORMING WITH THEIR HANDS). NON-
TRADITIONAL APPEARANCE AND
USABILITY EXPERIENCE MAY BE REJECTED
BY SOME USERS; POTENTIALLY LONG
LEARNING CURVE; POTENTIAL
PERFORMANCE DEGRADATION.

INTERACTIVE TECHNOLOGY
MOVEMENT SENSOR BASED
EXTERNAL SUPPORT / ALTERNATIVES
ONE OF THE MOST
SUCCESSFUL TECHNOLOGIES
HAS BEEN MICROSOFT’S
KINECT, AS IT HAS BEEN
DESIGNED TO ANALYZE
PEOPLE’S COMPLETE BODIES,
THEREBY ALLOWING FULL-
BODY MOTIONS AND
GESTURES.
STANDARD COMPUTER MICE REQUIRE CONSTANT MOVEMENT OF THE HAND,
WRIST AND ARM TO OPERATE. AS SUCH, THEY POSE MANY PROBLEMS FOR
PEOPLE OF ALL AGE GROUPS WITH DISABILITIES. IN ADDITION, USERS WHO
SPEND LONG PERIODS AT THE COMPUTER CAN DEVELOP REPETITIVE STRAIN
INJURY AS A CONSEQUENCE OF THIS CONSTANT MOUSE MOVEMENT.
AS THE NAME SUGGESTS 'MOUSE ALTERNATIVES' IS A RANGE OF DEVICES
(TRACKBALLS, JOYSTICKS, TRACK PADS, SWITCHES ETC.), WHICH REPLACE MICE IN
COMPUTING ACTIVITIES. THESE DEVICES ARE SPECIFICALLY DESIGNED TO ADDRESS
THE NEEDS OF COMPUTER USERS WITH LIMITED HAND CONTROL, FINE AND GROSS
MOTOR SKILL DIFFICULTIES, POOR HAND-EYE COORDINATION, LIMITED MANUAL
DEXTERITY, REPETITIVE STRAIN INJURY, INVOLUNTARY MUSCLE SPASMS, SPASTIC AND
FLACCID PARALYSIS, CEREBRAL MOVEMENT DISORDER OR CENTRAL
NEUROMUSCULAR DISABILITY AND INFLAMMATORY OR DEGENERATIVE CHANGE.
THE FUTURE
MORE THAN 84% OF CAD DESIGN
ENGINEERS REPORT A NOTICEABLE OR
SIGNIFICANT IMPROVEMENT IN THEIR
PRODUCT DESIGNS AND THEIR ABILITY
TO DETECT DESIGN PROBLEMS AS A
RESULT OF USING 3D MICE. - THE
AVERAGE PRODUCTIVITY GAIN
REPORTED BY CAD USERS WHILE USING
3D MICE IS 21%. - THE PAYBACK PERIOD
FOR 3D MICE IS VERY SHORT, TYPICALLY
LESS THAN ONE MONTH

LOGITECH HAS
INTRODUCED A NEW
WIRELESS TRACKBALL
SOLUTION (VIA USB
ADAPTER) INTO THIS
UNDERREPRESENTED
CATEGORY OF COMPUTER
MICE, THE M570 ($59.99
DIRECT). THIS ADVANCED
NAVIGATING PERIPHERAL
ALLOWS USERS THE
OPTION OF SIMPLE PLUG-
AND-PLAY ACTIVATION
THE M570 HAS A DARK GREY,
MATTE FINISH CONTRASTED BY
THE BOLD MARBLE-LOOKING
BLUE TRACKBALL. THE DESIGN
IS MODEST AND NOT OVERLY
LOUD LIKE MOST GAMING MICE
AND DESKTOPS TEND TO BE.
THE STRUCTURE OF THE DEVICE
WAS COMFORTABLE, AND THE
WAY MY HAND CURVED
AROUND ITS BODY FELT
NATURAL. IN BETWEEN THE
TWO MOUSE BUTTONS IS A
RUBBERY SCROLL WHEEL
THE M570 WEIGHS A LIGHT 4.8 OUNCES POUNDS, BUT HELD
FIRMLY IN PLACE EVEN IN MY MOST INTENSE GAMING
MOMENTS, BY THE FOUR RUBBER STOPPERS FOR
RESISTANCE. ALSO ON THE UNDERSIDE OF THE DEVICE IS THE
ON/OFF SWITCH AND A PLACE FOR THE AA BATTERY
(INCLUDED) TO POWER THE M570 THAT ALSO DOUBLES AS A
HOLDING PLACE FOR THE THUMBNAIL USB WIRELESS
ADAPTER. THE M570 IS A LITTLE BULKY, BUT IT HAS TO BE TO
SUPPORT THE TRACKBALL. IT MEASURES IN AT 1.7 BY 3.7 BY
5.7-INCHES (HWD),
THE M570 WAS
RESPONSIVE WHEN
PITTED UP AGAINST
EVERYDAY TASKS AND
THE GAMING GRID. ITS
18 MONTHS OF
SUGGESTED BATTERY
LIFE FROM LOGITECH
AND ITS VERSATILITY OF
USE ON ANY SURFACE
(SINCE THERE IS NO
MOUSE WAGGLING
REQUIRED) PROVED IT
WAS A RELIABLE
COMPETITOR.
