Optical joystick senses 4-way only

I've read people would like to have an on-screen cursor on their x1 and control it using the optical joystick. However, the optical joystick on x1 senses up down left or right, one way at a time only. It doesn't senses all directions and cannot move the cursor like computer mouse.

these are really bad news

thats what i thought but ... im not so sure about it yet.
the optical pad currently just emulates an scrolling wheel. and those are usualy 2/4-way only.
or do u know anything we dont know?

Well
Well, if my idea is right, the optical "pad" is simply the bottom of an optical mouse.
The difference in this case is that instead of moving the mouse, we are moving the detection surface.
So basically, unless it's specially designed only for 2 axis, it should, technically, detect all movement directions.

Exactly, it depends on whether the output of the optical sensor is converted into digital keypresses at the driver level or by hardware, and how exactly the optical sensor communicates to WM.
I have no idea where to start or how to go about finding this kind of thing out, let alone starting to program drivers/software for interception of the data.
I'm afraid it's a waiting game to see if there's anyone with the knowledge and expertise could do this, and another dice roll as to whether that person is interested enough to spend the time and effort in making a proper mouse style optical sensor a reality (or finding out after a lot of work that it's an impossibility...!)

Use optical track for fingerprint?

Just wondering; how does the optical trackball (like in HTC Desire) work?
It seems that this device must be capable of using that as finger print recognition as well. Just a matter of good software?

not a chance dude its just the same as an optical track pad on a laptop or the red light on the bottom of your mouse the hardware would never be precise enuf to be used as a finger print scanner.

Depends on the resolution of the scanner, and if you can obtain raw data from it.
However assuming that it has the resolution it would still be a pain to use since contrast over the finger is poor, meaning that you would need to light it from the side, and you would have to move your finger back and forth until a complete image was obtained.
Possible: In principle
Practical: Most likely not
Also since it's going to need raw data from the track pad chances are that you would have to hack the mouse (trackpad) driver, i.e. need root.

ok now thats impressive so maybe yes but if you were going to use it to lock your device it wouldn't be practical it would take so many different scans and from different angles

Use fingerprint reader as optical trackpad
Inversely: LG GW820 use a fingerprint reader as a 5 way navigator. From UPEK I think.
Does anybody know the manufacturer of the HTC Desire optical trackpad?

How to disable TSP Hovering / Air Sensor

I'm trying to figure out how to disable the TSP Hovering/Air View/Gesture Sensor. I've disabled all settings related to Air View/Gestures, but the Sensor is still there. If I hover my finger over a button in the Browser, I can see that it gets "highlighted."
However, in a Rom Emulator that I'm trying to run if I hover over any buttons they will be pressed, which makes the Emulator practically unusable. Is there any System App I can freeze or a setting I can set to lower or completely turn off the sensor? I know there's a Sensor Touch setting to increase the sensitivity when wearing gloves, so it seems like it may be possible to reduce the sensitivity in a similar manner.
Thanks!

[Q] Touch sensitivity increase button does not seem to work.

Impressed with the video in tube I bought this phone yesterday from the Samsun Sales Centre. While exploring the options of the phone I found that Increase touch sensitivity does not work i.e. the pen or pencil used as stylus in video does not work. pls guide me

Request Glove Mode (High Touch Screen Sensitivity for glove wear)

How do we get glove mode, it used to be available in the LG G3, but not on the Lg V20.
Afaik it's merely uping the sensitivity of the touch screen software threshold.
The screen hardware is capable of sensing touch under gloves.
This is evidenced by opening a draw app, pressing hard on the touch screen first to activate touch detection then release the extra pressure and you'll notice the touch continues to work until you completely lift the finger.
