An Overview of Mouse Technology - Page 9

post #81 of 110
@ test user: Well, it doesn't necessarily have to be smoother, or otherwise advantageous in any way for that matter. Just the fact that - again, how it is suggested in this article - there's some kind of different feel to it should qualify the possibility of using high sensor resolutions a viable aspect in mice. But you mentioned that yourself. Habits on the other hand don't seem to be too much of a factor as even players whose gaming histories don't reach as far back as there were only 400cpi mice available tend to prefer lower values after initially starting out with higher ones.
Another reason as to why I think this should've led to a change of mind especially in players is that I doubt that they, the players, crawl around in Windows with 400cpi on their 2000p screens. Most of them use the on-the-fly buttons to go up to at least 800cpi for non-game activities. But if you are really sensitive about this topic, you wouldn't want your mouse sensor to function differently for each field. Not necessarily sensitivity-wise because it's not like your 2D sensitivity will match your 3D one either way, but more in the sense of malfunction speed, jittering, precision, accuracy or even lift-off distance - all of which representing sensor performance issues that can function differently at different levels of CPI.

@ wo1fwood: I see. Would be keen for anyone to share some technical details about that; are sensors today still that "bad" that their best performance is to be expected not out of the 400-800cpi range? I don't see the difference in sensor performance between and 400 and 800cpi nowadays being anything noteworthy myself, so at least going up to that could provide players with a chance to experiment with what they are more comfortable with, especially considering that most of them use it for desktop activities also.

Well, yeah, what wo1fwood says. The general rule of thumb for optimum performance would be using the lowest native sensor cpi level, I guess. So it depends largely on the sensor. As far as I know, most mice perform better on lower cpi levels, and higher cpi levels often decrease tracking quality by increasing jitter and decreasing IPS.

Finally understand count resolution and how it's increased. Also explains why certain values are choosen.


What wasn't mentioned was the effects of count interpolation via controller recalculation, data allocation (inc. framerate, count vs speed etc) and polling which will specifically effect user perceivable ripple.

Think it would be cool if they offered any intern positons. Would learn a lot :DD

Brilliant, finally some insight from someone actually involved with R&D!

And finally an official statement that high dpi is bad biggrin.gif

I started watching this and after 8 minutes in I had to pause it to come give you a rep and a thank you for sharing this.

Oh wow, so much thanks for this!

So, the native resolution is limited by actual space the lense can cover, and interpolated resolutions are always worse, especially when far higher than what is native to the sensor. What about going for lower resoultions then? Also, what are the highest native resolutions of modern mice you guys know about?

I'd also like to know what the maximum amount of pixels you can get without interpolation is. Are even the lower dpi levels on mice a result of interpolation, or are values of under 1000 cpi possible?

They did at least in the past. wink.gif
