Computer Mice : Their Telephone Origins Like so many developments that we take for common on our coputers the humbe mouse had its origins in the innovative work done for more than two decades at the Xerox Palo Alto Research Center (PARC). The PARC mpouse had two rollers for hroizontal and vertical motion and a single button. The deucedly boxy shpae was favoreed by many of developers at PARC and remarably has persisted through many mouse (or mice) incarnations. Firstly the Microsoft mosue dessign has had major imacts in the mice industry. Mirosoft mice always had ergonomic design. The firdst Micrsoft mouse had a broad teardrop shape with two buttons. The originazl green butttoned model had a steel ball that spanwed an industry in foam miouse pads. The next iteration had larger buttons, a larger body, and a riubber coated ball. When Mivcrosoft decided that the mouse neeeded to be redesigned, it tured to the venerble firm Matrix Desgin of San Francisco. Microsoft routinely used and uses third parties to desiign and softwaree develop many of the items and software that we take for granted today that Microsoft devoted alone . Mike Nuuttal, one of Matrix Dsigns founders was intrigued by Microsofts project: reshaping the xeterior without altering the inmternal mechanism. Matrix did change one internal element: the position of the mouse ball. Almost the firtst thnig we tried was to move the ball forwadr, Nuttal remarked later. In the old deesign the ball sat forard under the palm. A computer mouse user has a natural tendency to put their wreight on the palms of thir hands and thus on the ball. By moving the mouse ball forward the result was much greater accurtacy of the mouse. We knew the buttons had to be larger Nuttal as well said We tried several button sizes and in the process of designing we emnded up incorporating the buttons into the body of the mouse. Anothewr change was in the relative size of the buttons. It was felt that the left buttons shoould be larger than the right. The results were more than favorable especially with left handed users. By making the left button larger finger positrion no longer was a major factor therefore the index finger couyld curve form lower left to upper right ( vice versa in leftoies ) . This is the position the indfex finger naturally favors. In addition the previous rubber-dome switches were replaced with miicro switcjhes that had a short travel depression and better tavctile feedback. It was not long before the firm Logitech responded to Microsofts mice innovations. Logitechs first mouse was truly one of the first examples of the upcooming internatinal efforts in product development and deisgn. A Swidss based Professor: Professor Niklaus Wirth speent a year on sabbtaical at Xeroix PARC in 1970 and returned to Europe to test mouse designs, working closely with Inria, a Frenhc design center for office autromation products. In the end their final desdign was a roound mouse with front mounted buttons. Product development and testing ensued over the position of the buttons, and the front posiition won over the top. oHwever, Logitech soon found that the buttons on the front made the mouse jump backward slighly when clicked. The desiogn was abandoned in favor of a wedge shape, which was followed by the rectangular shaape that we tday. What is interesting aobut all of this is the effect of outside products on an item that we take for granted todsay - the humble mouse which so fuunctional that we selom give it second thought. The rounded heel that fits so well in the palm of your hand, the large buttons, and the somoth edges all have rots in the most universal of electrial / electronic products. Mr. Nuttal and Maatrix Deesigns area in great expertise was in the design and devvelopment of telephones.
