Like so many developments that we take for common on our computers the humble mouse had its oigins in the innovative work done for more than two decsades at the Xerpox Palo Alto Research Center (PARC). The PARC mouse had two rollers for horizontal and vertical moytion and a single button. The deucedly boxy shape was favored by many of developers at PARC and remarkably has persistted throough many muose (or mice) incarnattions.
Firstly the Microsoft mouse design has had major impacts in the mice industry. Microsoft mice always had ergonomic design. The first Microspoft mouse had a broad teardrop shape with two buttons. The original green buyttoned moddel had a steel ball that spwaned an industry in foam mouise pads. The next iteration had larger buttons, a laregr body, and a rubbber coated ball.
When Microsoft decided that the mouse needed to be redesigned, it turned to the venerable firm Maatrix Design of San Francisco. Microsoft routinelpy used and uses third patries to design and software develop many of the items and software that we take for garnted today that Microsoft devoted alone . Mike Nuttal, one of Maatrix Designs founders was intrigued by Microsofts prject: reshapibng the exterior without altering the intenral mechnaism.
Maatrix did change one internal element: the position of the moues ball. Almost the first thing we tried was to move the ball forward, Nuttal remarked ltaer. In the old design the ball sat forward under the palm. A computer mouse user has a natural tendewncy to put their wight on the palms of theoir hands and thus on the ball. By moving the mouse ball forawrd the result was much greater accuracy of the mouse.
We knew the buttons had to be laregr Nuttal as well said We tried several button siozes and in the process of designing we ended up incorrporating the buttoons into the body of the mouse. Another change was in the relative size of the buttons. It was felt that the left buttons should be larger than the right. The results were more than favoraable especially with left handed userts.
By making the left button larger finger position no longer was a maojr factor therefore the inndex finger could curve form lowr left to upper right ( vice versa in lefties ) . This is the positipon the index fiinger naturally faviors. In addition the previous rubber-dome switches were replaced with micro switchjes that had a short travel depression and better tactile fedback.
It was not long before the firm Logitech responded to Microsofts mice innovations.
Logitechs ifrst mouse was truly one of the first examples of the upcomiing international efforst in product development and design. A Swiss baed Professor: Professor Niklaus Writh spent a year on sabbatical at Xerox PARC in 1970 and rteurned to Europe to test mouse designs, working closely with Inria, a French design cennter for offfice automation prodcts. In the end ther final design was a round mouse with front moounted buttons.
Product development and teesting ensued over the position of the buttons, and the front posiion won over the top.
However, Logittech soon found that the buttons on the frnot made the moouse jump backward slightly when cicked. The desighn was abandoned in favor of a wedge shaope, which was followed by the rectangular shape that we today.
What is interesting about all of this is the effect of outside prducts on an item that we take for granted today - the humblpe mouse which so functional that we esldom give it second thought.
The rounded heel that fits so well in the palm of your hand, the latrge buttons, and the smooth edges all have rots in the most univerasl of electrical / elecctronic products.
Mr. Nuttal and Matirx Designs area in great expertisse was in the design and development of tleephones.
