Optical mice in the test: Logitech Dual Optical against Microsoft Explorer 3.0

Introduction

After we saw the cordless -optical mice from Logitech and Microsoft have some significant restrictions, especially in tough gaming operations ellt, two more candidates have now arrived in our test laboratory who can be considered serious contenders for the first places on the rodent charts. Both the Microsoft Intellimouse Explorer 3.0 and the MouseMan Dual Optical from Logitech bring technological and ergonomic innovations that increase precision and work and Should facilitate game operations. Both candidates are optical mice, but they are on a leash - which means that signal and power transmission are carried out by cable as always. So you have to do without the 'wireless freedom', but this also eliminates two of the noticeable disadvantages of its cordless sisters: On the one hand, the problems that the power supply with batteries brings with it, and on the other hand, the inaccuracy that the radio transmission caused in some cases . Only by eliminating these shortcomings can the two miceUse their technological progress.

Technology

IntelliMouse Explorer 3.0

In the Intellimouse Explorer 3.0 , the technical innovations essentially include an increase the scanning rate of the optical sensor from 2000 images per second in the previous version to 6000 images/sec. On the one hand, this is intended to ensure that all hand movements are implemented precisely even with very fast movements on unsuitable, e.g. reflective, surfaces. On the other hand, the precision should of course be noticeably improved compared to the first generation of optical mice even under ideal conditions.

MouseMan Dual Optical

With the MouseMan Dual Optical , Logitech takes a completely different approach to increasing the precision of its mouse. As the name suggests, this latest MouseMan has two optical sensors. Logitech specifies their accuracy with 800dpi each. Unfortunately, this makes it difficult to compare with the information provided by Microsoft, which for its part, as already mentioned, has specified the unit “images per second”. It is clear, however, that Logitech also claims to offer unprecedented precision, which should be achieved through the coordinated interaction of the two sensors.

With both mice, the question now arises whether this theoretically promising technological advance can be achieved in practice proven and whether the further development was consistently continued in the areas of handiness and software.
