I am enjoying the KeyMouse Alpha for about a week now, and while I am getting more comfortable with it by the day, one of the issues is the mouse responsiveness. The size of the KeyMouse Alpha will probably always be a problem, especially with starting from rest position, where the force needed to set the mouse in motion could often cause you to overshoot. The 200 DPI Precision shift button helps greatly, but the difference between 200 and 1200 DPI (I am on a 3-monitor setup, so I do need the default movement that high) can be a bit jarring.

I was wondering if it was possible to implement some sort of gradual transition in DPI sensitivity when shifting into and/or out of precision mode. I don't know if the hardware allows it, or even if this one of those things that only sounds good on paper, but is it something you have tried/would try?

Hi Andri,
Here are a few things to try:
1. You can create macros for {monitor left} and {monitor right} which helps in multi-monitor setups (see YouTube video attached)
2. I personally keep mine about 800 dpi which requires more movement on multi-monitor setups, but does help with precision. You could also do the opposite with a "Shift DPI 2400" or "Shift DPI 3200" to speed it up when transitioning between monitors.
3. You can also use "Shift DPI 400" or "Shift DPI 800" as different buttons for different speeds.

Currently it would be quite tricky to implement a gradual transition, but sometimes these ideas roll around in our minds and we find a way to implement.

@Andri We've recently been testing with some ceramic feet instead of teflon feet, and the results are very encouraging. We have a force gauge, and it's almost half the friction. Precise movements are a LOT easier :) We'll be posting a video showing some testing. We're currently doing research to find a good source for them...the samples we bought were a bit pricey, but it's night & day difference for how easy KeyMouse Alpha glides with them. If we can find a good source, we'll post some on our website as an upgrade, and future KeyMouse Alpha devices will likely ship standard with them.

@Heber, Ceramic mouse feet sound very good. If you are unable to find a source at an acceptable price, would you mind sharing your current pricey source? I can't seem to find anything by searching on the internet.

@Andri Attached is a link to the one we're testing which glides well. It's thicker than our current teflon feet so it may interfere with mouse tracking, so it might be best to wait until we have fully tested. We'll let you know when we have our own fully tested solution.

Thank you @Heber,

Could you post your evaluations of the ceramic feet in a normal desk area and the low-friction mouse pad you guys have at the store. I am interested to know how Teflon feet on the hard mousepad fare vs ceramic on normal desktop surface. Also if it's not too much to ask, could you test the ceramic feet in a cloth mouspad surface as well?

Here's a video that shows some explanation (doesn't show doing the actual tests, but talks about the results). We've done some testing on cloth/neoprene mousepads and it works good (maybe about the same as teflon or slightly better), but not as drastic of a difference. Using a hard top mousepad or directly on the desk has a significant improvement with the ceramic feet, so we would recommend hard top mousepads with these. We'll post more as we get more info.

Wow! Pretty excited about this! Are there any adverse effects on the tracking?

The ceramic feet are a little taller than the teflon (0.75mm thick instead of 0.5mm), so we just have to be careful that it doesn't raise the device too high for mouse tracking to be good. In my testing it's fine, but worst case we just have to adjust the height of the 3D printed circles that they stick to on the bottom of the device. Some older versions of Alpha don't have these adjustable circles (which we use to fine tune the level of the device), so older versions may require some basic mods for it to work, but I think it will be worth it. It might be a total non-issue. We'll know more when we get our custom samples. You probably notice in the video that the ceramic feet are domed just a little. This makes the contact point very small, which is great for hard top mouse pads/surfaces.

From a tracking standpoint, it could be an issue for some that it tracks too easily while typing (maybe), but for me it's not an issue since my hands rest on the devices while I type. Overall, I'm pretty excited about it. It's a "game changer" upgrade for KeyMouse Alpha to glide more effortlessly like a "mouse" in our testing so far. For graphics work, etc. it just makes those precise movements so much easier. We're looking forward to getting these available as soon as possible.

The ceramic feet arrived today (amazon messed up the first order) and they are unbelievable. I am using Keymouse Alpha on a laminate surface; no mousepad. With the ceramic feet it glides better than my Logitech MX Master, even with all the weight, and it tracks just fine. Pretty sure if you manage to incorporate these into Keymouse Alpha, it will make it even more of a killer product.

@Andri :) I'm glad it's working well for you. This is really a game changer for KeyMouse. We're working with a supplier to manufacture them for us. They estimate our samples will be ready in about 4 weeks. Thanks for posting your experience with them here.
