can the G1 calculate surface area of a point touching it? or would it be possible to do that? it seems like it could work, but i'm not sure lol or else i wouldn't be asking this.
the reason i'm asking this is, we can make apps that emulate "pressure" so if someone barely taps the phone, it will have less surface area, and if someone presses the phone hard, it will have more surface area, there could be A LOT of things done with it
Don't see why not being it has been shown to be able to handle multi-touch. I agree though... would have many possible applications
yeah it could be used for games and such where u could see how fast you can match the weight on a weighing scale of some sort. i'm just saying it should be easy since we've seen multitouch on the phone. this would have an extra benefit over the iphone.
People are always asking for scales on touch screen devices and never get them.
Or finger painting with pressure driven line width or opacity!

The scale idea wouldn't work on a capacitive screen. The sensor detects the area being touched and then approximates the center. The idea of a "pressure sensor" would have to adjust based on variances from the initial contact. My thumb would make a much bigger initial contact than my pinkey, that doesn't mean I'd be pushing any harder.
but it is basically inferred that everyone will be using their thumbs for these types of apps so it wouldn't matter. but HEY guess what? its basically proven that the G1 CAN infact determine "pressure"!! i've had this app for a while now, but i just recently opened it up again to mess with it, and to my surprise, i noticed that the app could tell how much "pressure" i was puttin on the screen. now i dont know if its actual pressure its calculating, or if its the surface area it is calculating, but it sure as hell knows the difference between a light, medium, and hard press.
the app is called BouncingBall in the games section (it would definately be the last place i would see a pressure sensitive app lol) it may seem like such a dull app (no offence) but it really is a great concept. try it out. you just click the screen, and a ball appears where you tapped the screen, and depending on how hard you tap the screen, the size of the balls differentiate. and i know it isn't a "how long you held the screen" type of thing, because i pressed the screen pretty hard a couple times very quickly. like a quick hard jab with my thumb lol. and the ball that was created was large. but anyways, test it out.
I'm not sure if pressure data is made available/enabled in Android, but the synaptics touchscreen and driver definitely do support pressure detection. Check out the driver in git:
http://android.git.kernel.org/?p=ke...drivers/input/touchscreen/synaptics_i2c_rmi.c
and search for ABS_PRESSURE. Technically it's a misnomer as capacitive sensors don't deform or directly measure pressure in any way. "Pressure" is actually the change in capacitance as a finger (or any other object) approaches the touchscreen. It is used by the driver to determine thresholds for which the touchscreen should signal the system finger_down and finger_up events. Since no contact is needed to measure a capacitance change, the sensor may actually report a change in "pressure" even before the finger has touched the screen.
Still, I don't think this would be a very good idea for use as a user input. One reason is that everyone's physiology is different. My thumb lightly touching the screen may give a value of 10, whereas your thumb lightly touching the screen could give a value of 20. Another reason is that I don't think it would be very wise to encourage users to be liberally applying pressure to the screen.
hello,
i'am thinking of how to improve fingerfriendly navigation even on today screen, where you have to precisely have to mark the spot. i came up with an idea which i cant do because of lack of programming skills. but i made a picture where you can see my idea.
the idea is, when you touch the screen, a small crosshair will apear, pointing the exact location you want to click. if you want to click, you have to rise and press again the touchpad (same behaviour like laptop touchpads.
if you want click the bottom area, the crosshair swaps to the downside of your fingerpress, so that you can see the crosshair again.
sorry for my bad english, but i hope u get the point of my idea.
what do you think?
greetings
why is there a penis on your photo?
i did noticed too! rofl
LOOOLLLL
I was thinking about the same thing !!!
As Per Dev and Hacking Rules, this thread will be moved to Q&A Section.

LOL
You make me laugh a lot!!
Hahaha!
might not be a bad idea as long as you don't have to use your penis
Too bad his drawing skills make us think phalic thoughts, but yes, it is a good idea if it can be pulled off... I know my parrents would be more interested in using a phone like ours if there was some way to know where exactly you were clicking...
Would you want the cross hairs to be right under where your finger is, or would you want the application to have your finger PUSH the cross hairs around the screen, so your finger doesn't actually cover the spot the cross hairs would it?
the crosshair has to be visibile all the time a few millimeters over the finger...
and to all the poeple out there, this is not my penis on the picture, its a finger! (my penis is bigger anyway...)

ha ha - I think we all knew it was suppose to be a drawing of a finger but it kind of looks like - Well you know - Kind of funny - but the idea is pretty good.
I've been looking for a app to do this and cant find it. Basically the situation is this, I'm a painter (interior) and like to post before and after pics. The thing is that it it impossible to get the angle right to do it close enough to exact same location. I'm thinking it wouldn't be difficult to somehow use that panoramic effect the camera already has to overlap the before and after images. Anyway if you could develop this app the loads of money would probably roll in for you. Thanks for looking!
From my understanding it would be very difficult to have a app do this as it is all down to perspective (as you say same place, same angle etc).
If it was me I would create a mount to hold the phone (or buy one),
-I'd go for a piece of wood with a cheap phone holder on top
-Add a couple of cheap spirit levels - to get the rig level
-The height from the ground would be set by the mount
So with the above you've got the height, and angles (of the phone/camera) fixed.
Then if you didn't want to do it by eye, I'd add a mounting point for a laser tape measure to get your distance from a couple of fixed points.
And then take a couple of pics and when you've finished your work, go back in use the laser to get the correct point in the room, then level the mount, and take your after pics.
A bit hashed together I admit, but I can see no reason why it wouldn't give you what you needed.
Thats pretty much what I'm doing to be honest I'm just kinda standing in the same spot and shooting the pics. Think about it though the panorama photo does this already. I just want to use a previous photo as a transparent template to shoot over which would take much less time and give me better results. I understand your answer and appreciate the effort but for me as a painter to to take the time to set up a contraption to hold the camera, take measurements then take it all down to paint the room then set it up again takes too much time and time is MONEY. That's why I want an app to do it for me quickly.
Thanks a lot for the input though I'm still working on it.
Any idea where I might post this to get more views or is that frowned upon?
i was wondering if there's a lockscreen app that just shows your current home but non responsive til you tap your screen a preset number of times that way you can still see your android homescreen so you don't have to unlock it to see your live widgets and maybe to add some eye-candy to it the taps could crack the glass at the point where you touched the screen the final tap that unlocks it could shatter the glass and restore responsiveness to the device...sort of a "break glass in case of emergency" feel to it. can this be done? If yes, how hard would it be and does anybody else think this is a good idea? And lastly does anybody wanna take a crack at it?
Hah that'd be pretty cool... Mainly for showing off
maybe an interested app dev will see this post i would love to see this on a device and not just in my head
Something like that would totally rock. Although, I'm afraid you could still unlock the phone accidentally if it were in your pocket. I know the screen can register a touch through thin fabric, of which a lot of pockets are made of. Maybe make it quadrant based. Two taps in the upper left and one tap in the lower right or something along those lines. Don't even have to have lines on the screen or anything like that to differentiate the quadrants, just a fuzzy logic system that can figure out what your trying to do.

Interesting!
Along that same idea ...
Maybe a re-skin of the Lock Pattern currently utilized in Android.
It could, under some setting, take a screen shot of the home screen.and when the device is locked, display that screen shot.
Your idea of the invisible quadrants could be expanded to equal a 3 by 3, or a 4 by 4 square, instead of dots. And it could be set to recognize taps or swypes.

That may work, but I think it may start to get a little too complicated then. My thinking is that if you have three or even four sections wide/tall, it may be much more difficult to hit a particular area, that's assuming there are no visible dividing lines. Invisible quadrants would be much easier to tap and swipe without worrying your not hitting the correct area.

These little random ideas for apps never really happen, it is rare that anyone actually fulfils the wishful thinking of random users. I would be heavily surprised if this is actually carried through with.
Fantastic idea, though. If you ignore the negative, with the right effects and work this could be quite good.
Hi.
Im not new to forum, but on the other hand I havent contributed much..
But hey, sometime ot to be your first
I've made a gam for android and I would like some opinons, tips, device checks and bug reports.
Only if you have some time to spare of course
Here's the link: https://play.google.com/store/apps/details?id=com.daskaktus.particles
Thank you!
It can be a good game. It almost never detects my fingers. It is hard to see the particles when I have 2 or 3 fingers on the screen (sometimes one finger). The main screen is hatsto navigate also. It is a good concept, but not executed well enough. Keep updating, I'm sure it will get better.
"Give a man a fish you feed him for a day, teach him to fish, you feed him for a lifetime." In other words help others find an answer don't just give it to them.
Thank you for some feedback.
Yes I know that the menu could be more inutiattive, I will work on it some more.
And I too think it's hard to se the particles when my fingers are on the screen, but I guess the larger the screen, the easier it gets.
I'm currently noticed that on high resolution screens the particles and the player ball becomes small and hard to move so this i'm currently working on.
Other than that all I can say is, get thinnner fingers
