Turn HTC logo into a capacitive button

Switchbitch · Mar 18, 2013

I don't have an HTC One but here's my 2 cents anyway.

You're probably all aware that capacitive screens use a conductive matrix on the digitizer layer to sense the position of finger presses. Presumably, when a digitizer is manufactured it is most cost effective to lay the conductive matrix down across the entire surface of the digitizer, and not bother 'missing it out' in areas that are not required to be touch sensitive, i.e. across the HTC logo. Since there are touch sensitive areas to the left and right of the HTC logo, it seems sensible to assume that the conductive grid is present across the HTC logo also.

There's an easy way to check whether this is the case.

The conductive matrix is visible on the surface of the digitizer when viewed at the correct angle in bright light. It usually looks like a criss-cross of almost invisible tiny dots or squares across the screen. If you hold the HTC One at the right angle in a bright light (with the screen off), you should be able to determine if the conductive matrix is indeed present across the logo. If so, it would be logical to also assume that this area of the digitizer can receive an input.

It would have been nice to make it a home button + notifications colors,but HTC lacks creativity sometimes...

It would have been better if HTC made it the home button and the home button the multitask button but I hate having a home button logo which would act as multitask and a logo which would act as home button. Anyway it doesn't really matter if we figure out how to make a button out of the htc logo we can use any set up we like.

And, might I add, that whilst turning the branding into a button, swipe2wake might be a good idea as well. That little button also houses the ir blaster so the less it is abused the better

I am sorry, but I think the HTC logo is not inside a touchable area. I just connected my ONE via "adb shell getevent -lt"
an then without any presses on the touch screen the following is repeating:

Code:

/dev/input/event8: EV_SYN       SYN_REPORT           00000000            
/dev/input/event8: EV_ABS       ABS_X                fffffff6            
/dev/input/event8: EV_ABS       ABS_Y                00000036            
/dev/input/event8: EV_ABS       ABS_Z                00000100

If I hit the HTC logo, no other lines appear.

best regards
Daniel

Holy smokes if we can get this working i guess im buying this phone lol.

You're buying this phone based on the HTC logo being mappable?

In other news, having a separate touch panel for the buttons doesn't make any sense from an engineering or economic perspective, not only is it harder and as a result more expensive to install one big and two small panels versus one slightly larger panel, it is obviously more expensive to purchase 2 extra panels per phone. I would say that based on this bit of fact and from their previous choices in hardware design, that the whole panel below the screen is most likely part of the same touch panel as the screen. It is not only possible, but in fact very easy to make the kernel ignore clicks within a certain set of coordinates resulting in get event not returning any presses, but the idea that the HTC logo wouldn't be mappable is completely ridiculous.

This is just not true. On the lockscreen, I can drag the ring down into the bottom bezel and across all three buttons without losing control of the ring.

This proves that it is possible, I just have to define a new touch button in the kernel source and we are good to go.

PS: I plan on getting the dev edition of the HTC One once it is available.

Good to have you on board. Wasn't planning on rooting until the weekend but if you need any tests running that require su I don't mind jumping earlier (apart from anything else every day that goes by adds more stuff to my phone that dev unlock will blow away!)

No offence but I don't know you or of you. BUT, you already sound awesome :good::good::good::good: My HTC is on Order and already this changes it all. Initially I was dissapointed at the lack of a menu button as I hate the way the on screen menu buttons move around depending on apps. This will be a must! Thanks in advance!

djbenny1 · Mar 18, 2013

so what are we looking at here - im assuming it should be customisable, but for me i think keeping back as back and home as home are obvious.

that would then leave the HTC button to be menu?

sr1ks · Mar 18, 2013

I would assume.. if we do remap the buttons.. it would make sense to make the HTC Button do.. Home/Google Now..

the Home Button for Multitasking/Menu

and the back from back\kill app

+1 to this suggestion.

voltron2k11 · Mar 18, 2013

back button> back
htc button> menu or when pressed long multitasking or google now
home button> home .. d'uh

That is my suggestion ....

yea it would really annoy me to know that the home button didn't actually have the "home" function

OCD maybe lol

same here .. when it comes to my phone I get horrible OCD haha

erikivy · Mar 18, 2013

I can see now that the only acceptable solution will involve allowing the user to define what the buttons do.

sr1ks · Mar 18, 2013

I guess we could have an app/settings in the later stages of development to customize all button functions

since one solution will not make everyone happy...

but i guess first priority is to get the htc logo to work.. (and somehow get htc to do this officially..)
