First time trackpad user: should moisture on thumb severely degrade performance?
- I came from the 9000 so this is my first trackpad device.
I live in Miami where there's a lot of humidity.
I also have dry hands so I use moisturizer a couple times a day.
I'm finding that if my thumb is not completely dry (not like it's wet...just moist from humidity or moisturizer)...the trackpad becomes much less responsive to flicks of my thumb. When dry, I feel like it's exactly like using the trackball on my 9000...
Is this typical of a trackpad or is there perhaps something defective with mine?
Thanks in advance for your input.08-15-10 09:55 PMLike 0 - You may be getting a slight film from moisture that could obscure the optical sensor somewhat, that's the only thing that might affect your usage I can thing of. It's not a capacitive sensor, it works the same way as an optical mouse.

The trackpad is supposed to be better...and in ideal conditions it is - but it's so humid here during the summer that if I'm outside I'm finding the trackpad pretty much unusable.
I just wonder if this is normal or not.08-16-10 08:22 AMLike 0 - John YesterRetired SuperstarOn humid days my thumb drags a bit, but other then that it works fine.08-16-10 10:02 AMLike 0

Since I had no basis of how a trackpad -should- work, coming from a 9000, I did not realize that my issues were not normal. It is normal for the moisture to make it harder to swipe with the trackpad, but it should still work fine - mine was not. I ended up swapping my Torch for a new one at AT&T and it's much better! That's the only minor defect mine had and my new one seems perfect.09-14-10 11:54 AMLike 0 - I have noticed this problem not only with the trackpad, but also with touching the screen.
When my hands are extra moist, my fingers do not move smoothly across the surface.

- Understand the trackpad is an optical sensor.
It is not a conductive sensor like a touch screen/touch pad.
In fact you can test this by running your finger just above the surface of the track pad... you will still be able to move things around.
When your finger is moist, the H2o on your finger surface scatters the optical beam reflecting off your finger and the moisture also tends to fill in the 'voids' of your skin surface, which the track pad uses to measure movement.
Are some track pads more sensitive to this?.... maybe... and that's possibly why another device is working better for you. Just realize it really doesn't have anything to do with the 'drag resistance' across the surface of the pad.09-14-10 01:44 PMLike 0 - I don't know the exact humidity levels in my country (it's pretty much the same all day, at least during the times it matters) but I guess it's still pretty high. Never experienced a problem with the trackpad on my Curve 8520. I move around quite a bit every day and never a day pass without me perspiring buckets. Crappy climate if you ask me.09-14-10 02:36 PMLike 0

- I live in a humid climate (Texas) and notice some slow down of the trackpad if I'm sweaty from exercising or being outside on a hot day (like lately). It still responds, just slowly.09-14-10 04:18 PMLike 0
