Logitech IFeel Optical Mouse
Page 5 of 7

Build & Design
Notwithstanding the "plasticky" feel, the mouse is solidly built, offering the same comfort and usage for left/right-handers alike. On a personal note, I prefer a smaller mouse design, rather than the bulky but ergonomic MouseMan variants. This facilitates gameplay by allowing easy side maneuvers, propelled by my thumb or 4th finger.

A perfectly snug fit

Optical Impressions
Generally, the mouse is both smooth and responsive, serving my needs well for generic Windows usage. Even when used on my Q3A Everglide board, the white wordings didn't pose a problem for the IFeel's optical sensor.

But having said the above, I still can't adapt to "Quakin'" with the IFeel mouse. The accuracy of movement is definitely there - a testament of its optical performance. Yet somehow, the absence of a roller-ball beneath makes it extremely sensitive to motion shifts, especially abrupt turns. Even after playing around with acceleration cum sensitivity settings, I still couldn't find a sweet spot for my liking. But knowingly, this is more an issue of acclimatisation and "upbringing". With time and practice, I am confident that this can be duly addressed.

In general, the optical performance really "shines" (note: pun ) and I have no qualms with its mechanism at all.

The IFeel Experience
But the ultimate question lies in how IFeel actually improves a user's interaction and experience whilst working in the OS. In that regard, IFeel works predominantly well, and literally, one can feel his way around the desktop. However, I actually preferred a subset of actions to be mapped to IFeel vibrations, rather include the whole enchilada, which made it just too disruptive for use.

In addition, although each action is fully customizable, there is a real difficulty in adequately feeling and discerning these actions aptly, unless one customizes them to be vastly different. And despite the whole myriad of customizations allowable, much of its nuances are effectively lost and attenuated upon reaching the external shell. But don't get me wrong. The issue doesn't lie with the FFB strength of the mouse (believe me, it can gyrate pretty violently ), rather it is more an issue with our internal sensors, that aren't as sensitive or trained to feel the finer changes. Perhaps if one puts a visually impaired individual, with a much better developed sense of touch, the IFeel could serve as the perfect interactive experience. However, for individuals like myself (with a sub-par touch-sense accumen), perhaps Immersion could consider introducing more effects with drastically different characterics, before a better sense of feel round the desktop is actuated.

Another moot point is the limitations of the TouchSense recognition engine with regards to the OS. Whilst the mouse certainly does vibrate in active response to how one customizes his/her own IFeel experience, the engine probably uses "mouse-overs" (a programming term that signifies a pointer entering a certain pre-defined widget or GUI component, in Windows) to discern its activation. By and large, rectangular GUI boxes (like window borders, task bar sides, etc) with clearly defined edges are excellently represented. However, when it comes to GIF icons with transparent borders, the mouse begins vibrating even before "hitting" their physical outline. But having said that, I believe this is an inherent issue within the OS, that programmers have no way of circumventing or exploiting. Thus, I can't really fault them in this arena.
