touch sensor

After seeing some potential issues with the Nexus One multitouch, Android and Me has taken some time to visit the topic a bit more in depth. It appears as though the Nexus One touchscreen is not really "broken" like first reported, but more so limited by the hardware. The screen used in the Nexus One, the ClearPad 2000, is indeed designed to handle multitouch functionality, and in many cases like Google Maps, or the gallery, these features work rather well.

The issue appears to become most transparent when third party developers use more complex motions in their games, and the device can simply not keep up. While unfortunately it doesn't seem like there is an immediate fix for this, besides developers "dumbing" down their games to not include these extreme multitouch needs, we can all hope that HTC will upgrade their choice to the ClearPad 3000. Check out the performance of this screen after the jump. [via Android and Me]

Looking Closer at HTC's Touch Sensors

I was really sad when I read about this on XDA developers forums, my brother ipod touch can recognize more than 2 fingers in the piano apps. On the other hand, I downloaded several piano apps for my Nexus 1 and ZERO could recognize more than 1 finger on the keyboard, this is very relevant because you can only play one note at a time, forget doing chords.
Well, like you said there arent many games or apps for REAL multitouch on Android (actually I would call it DUOTOUCH), shame because some developers can give up on better multitouch apps for android.
Please see this interesting topics:

I think they should use the Clearpad 3000 with REAL MULTITOUCH.

Except of this, I love my Nexus One.

Sad to see HTC cut a corner on yet another phone, especially the flagship Google phone. I used to own 2 HTC phones and always thought the build quality wasn't that great.

N1 still looks real nice but there is no excuse for them to cut this corner and go cheaper on a part.

the N1 for verizon will be the exact same phone except for it being CDMA. dont let this crap scare you, the N1 is an awesome phone and by far one of the best as is

Personally, I'm okay with the way the Nexus One works with multi touch. Because of my disability, I have very limited use of my fingers so I can't do more than simple two finger movements anyway. I know that manufacturers like HTC will eventually switch over to better hardware like the ClearPad 3000 because that's what people will want. I just hope that Android and the related apps leave in options for simple one or two finger gestures like swipe and double tap along with the more complex multi finger gestures. If not, then these gadgets will become too complicated for me to use. What will I replace my N1 with if that happens?

Its sad that HTC cut corners like this, the iPhone capacitive touch panel support more than two finger inputs, five fingers.

Htc and Google dissapoint me more and more everyday. i do not understand why such inferior products are being sold as premium, ie 5-600 phones with issues like this. Google for not having any standards to putting great software onto inferior hardware. What good is multi touch on the phone when the hardware cannot support it, or as in my hero, multitasking, the os can do it wonderfully, but the hardware cannot.

I also am extremely disappointed with Google and HTC, I had gone thru 2 defective Nexus One's in two weeks time!!! 3G issues, that the OTA update didn't fix, the microphone blew out on day 2! I returned the phone for a new one and the second one had multitouch issues!! Bad service and support from HTC and Google!!! I am waiting on my refund now, which has been like pulling teeth to receive!!!

I am not impressed!!

On the brightside, maybe these multitouch issues protect HTC from apples crap lawsuit. lol. Get over it people, multitouch is overrated anyway. I use a Droid here so not sure how it stacks up against HTC, but it more than holds it's own against my ipod touch.

I don't see real need for multi-touch in android. Other than games that is. I find it easier to double tap to zoom and have the text re-sized to the screen than using the pinch to zoom.

There are other things with the N1 multi-touch that I have noticed. With latest Cyan rom I have noticed that multi-touch is getting all confused and detecting two fingers when there is clearly only one touching the screen. If I close the programs and restart it the issue is corrected. Also some times I have to restart the phone for this to stop. It seems like software glitch more than hardware issue.

The multi-touch is limited to a square. It does not detect the actual 2 points but it just reports the spread of the fingers. This is adequate for zooming functions but not enough for keyboards and video games. I dont care about the games that much... I have more of a problem not being able to save PDF attachments in the mail client.

Just my .02c

Other than useless piano and toy apps and some games. Ask yourself what real world practical use would I need more than two fingers on a tiny 4.7 inch display? Answer: NONE. The ClearPad 3000 which is capable of registering up to 42 simultaneous touch events is WAY overkill for a tiny portable device such as the N1.

There were no corners cut. The N1 in part was specifically designed for the dualtouch panel. Pinch zoom, pivot and no more than two touch events is enough for >99% of users.

As Google did not feel the need to have a panel that only <.01% would fully use it's capabilities. The intent of the N1 was to showcase Android. Not to be a iphone killing game machine.

Though multi touch doesn't really bother me very much since I do barely use them on my application I just do hope that this feature will be given proper solutions on the next phones to come out.

The place where I most noticed the lack of working multi-touch is the virtual keyboard.

The iPhone virtual keyboard is awesome. It handles multiple simultaneous keypresses without a problem. It auto corrects like magic.

On an Android phone, it only takes the second keystroke unless it gets confused. Most displays don't resolve key presses as accurately as the iPhone. End result, you can't type as fast on an Android phone. More like hunt and peck. I can type amazingly fast on an iPhone... laptop keyboard speeds. Makes a big difference on when you'll settle for using a phone vs. a laptop.
