TrackWeight: Turn your MacBook's trackpad into a digital weighing scale

benoau•1d ago
There used to be iPhone apps that did something similar -

https://www.theverge.com/2015/10/28/9625340/iphone-6s-gravit...

ashertrockman•1d ago
If anyone happens to be using an iPhone 6S... http://touchscale.co/
hackmiester•1d ago
This worked all the way up through the iPhone Xs.
jmb99•1d ago
The single most irritating killed feature from Apple. Redesign half of their UI to rely on 3D Touch to make sense, then get rid of 3D Touch without redesigning the UI. Previewing links, moving the cursor, interacting with items, they’re all “press and hold until haptic feedback” instead of “quickly press hard and get immediate feedback.” Easier to accidentally trigger, slower to trigger on purpose.
05•1d ago
Hardware cost+extra weight (need to make the glass thicker to be able to handle extra force and not push on the display). Turns out nobody was really using it because discoverability sucked..
jmb99•1d ago
Hardware cost & weight, fine. Glass doesn't need to be thicker than it currently is (I can press on my 13 Pro's screen about twice as hard as was needed for 3D Touch's max depth, and no issues with the screen), and the last time I replaced a battery on a 12, the screen was just as thick as the XS.

>Turns out nobody was really using it because discoverability sucked..

Sure, but then redesign the UI after removing 3D Touch to not be equally undiscoverable but less precise. Even on the latest iOS beta with its full redesign, there's still many, many actions that require a long press that are completely undiscoverable. (For example, if you don't have the Shazam app installed, go find the list of songs Siri has recognized when asked "What's this song?" Don't look up the answer.)

echoangle•1d ago
> Glass doesn't need to be thicker than it currently is (I can press on my 13 Pro's screen about twice as hard as was needed for 3D Touch's max depth, and no issues with the screen)

I dont think this is a great argument. The glass maybe needs to be thicker so the sensors on the border can properly measure the pressure, not because the screen is close to shattering.

sejje•1d ago
Maybe you had a hard time parsing his comment.

He is capable of pressing twice as hard as the feature required at maximum. The screen handles 2x the maximum without issues. Therefore, the glass is thick enough to handle half that pressure,as required by the feature.

It's a good argument.

echoangle•1d ago
As far as I know, the pressure is measured around the edge of the screen. If the screen is thin enough, it could bend when pressed and the pressure applied to the center of the screen can’t be properly measured. I don’t think the problem with a too thin screen is the screen breaking when pressing it.
simondotau•23h ago
For what it’s worth, I made the same parsing error upon first read.
mitthrowaway2•19h ago
stiffness != strength
cluckindan•1d ago
Nobody? Really? It’s definitely the UX feature I miss most on modern iPhones. Long press feels janky in comparison.
gxs•1d ago
Really? For me it’s the “open image in new tab” option in safari

Have no idea why you’d go out of your way to do that other than placating image sharing services

yoz-y•1d ago
The discoverability sucked because Apple never rolled this out to all of the devices, themselves grossly under utilized the feature and eventually ghosted it.

It was by far the best cursor control paradigm on iOS. Now everything is long press which is slow and as error prone.

I’m all for proposing different paradigms as accessibility but 3dtouch was awesome.

macNchz•1d ago
3D Touch was amazing for typing alone, I miss it basically every day when I type more than a couple of words on my phone. It was so great to be able to firm-press and slide to move the insertion point, or firmer press to select a word or create a selection. It was like a stripped down mobile version of the kind of write-and-edit flow of jumping around between words that I can get on a proper keyboard with Emacs keybindings drilled into my brain.
Creeot•22h ago
You can still move the cursor by long pressing on the space bar, in case you didn't know. There's no equivalent replacement for the selection behavior you're describing, though (as far as I'm aware).
Wowfunhappy•20h ago
I don't understand why Apple doesn't just let us slide to move the cursor, who needs force touch?
bagels•1d ago
I hated when my mother in law came to me for help using her iPhone. She had a hard time controlling and understanding 3d touch.
behnamoh•1d ago
I don't like it when old people are the reason the rest of us can't have nice things. Some grandma in Nebraska can't use 3D touch and now the rest of the demographic of Apple's customers are deprived of it.
wat10000•1d ago
There was a principle of UI design that all UI actions should be discoverable, either with a visible button or a menu item in the menus at the top of the screen (or window on Windows). This is annoying for power users and frequently used actions, so those can also be made available with keyboard shortcuts or right-click actions or what have you, but they must always be optional. This allows power users to be power users without impacting usability for novices.

We've been losing this idea recently, especially in mobile UIs where there's a lot of functionality, not much space to put it in, and no equivalent of the menu bar.

nottorp•1d ago
When I had an iPhone XS i could never understand how to predictably do a normal touch or a 3d touch, or where exactly the OS has different actions for one vs the other.

And I play games [1] using just my macbook pro's trackpad...

[1] For example, Minecraft works perfectly without a mouse. So does Path of Exile. First person shooters ofc don't.

allending•22h ago
For many, old people are the reason the rest of us have nice things.

My memory was that the weight API was made private because they didn’t want people using iPhones for drug deals.
Wingman4l7•9h ago
Apple, policing use of an API on a privately-owned device for purposes of a consensual, non-violent activity that is only technically a crime in some legal jurisdictions? Sounds about right.
cryptoz•1d ago
You can use any phone with a barometer to make a scale. All iPhones since the 6, and all the Pixels, and Samsung flagships have one. You get a zip loc bag, blow some air into it, put your phone in running an app that shows the pressure in a big font (so you can see it through the ziploc). Then you put an object of known weight on it like a quarter (balanced carefully on top of the air-filled ziploc) and note the pressure change on the display. With that, I think the weight / pressure change scales linearly, so you can now weigh anything small that you can balance on the ziploc.
jbverschoor•1d ago
Dropbox shouldn’t exist either bc we have rsync ;)
Nathan2055•1d ago
The infamous Dropbox comment[0] actually didn't even cite rsync; it recommended getting a remote FTP account, using curlftpfs to mount it locally, and then using SVN or CVS to get versioning support.

The double irony of that comment is that pretty much all of those technologies listed are obsolete now while Dropbox is still going strong: FTP has been mostly replaced with SFTP and rsync due to its lack of encryption and difficult to manage network architecture, direct mounting of remote hosts still happens but it's more typical in my experience to have local copies of everything that are then synced up with the remote host to provide redundancy, and CVS and SVN have been pretty much completely replaced with Git outside of some specialist and legacy use cases.

The "evaluating new products" xkcd[1] is extremely relevant, as is the continued ultra-success of Apple: developing new technologies, and then turning around and marketing those technologies to people who aren't already in this field working on them are effectively two completely different business models.

[0]: https://news.ycombinator.com/item?id=9224 [1]: https://xkcd.com/1497/

OskarS•15h ago
It's also not the same thing as Dropbox was offering: that's a description of a network drive, but the key thing about Dropbox is that it's a syncing engine. It's a much harder thing to do, but with very big benefits: much faster (since it's just reading off disk) and offline access.

ChrisMarshallNY•1d ago
By "downloaded," I expect that you mean "Built, tested, and deployed." It's not an App Store app. It's basically a technology demo. Get Xcode, and build it and run it.
lucasoshiro•1d ago
A .dmg or at least a CLI instruction would really help
ChrisMarshallNY•1d ago
You could always request that from the author. Since it's a Mac app, they could do that. Not so, if it were an iOS app.

It's a pretty basic SwiftUI app. They haven't really polished it, so I could see why they might not be interested in making it much more accessible. It's a tool for Mac geeks.

Speaking for myself, I have a whole bunch of packages, and almost every one has a test harness. Many of the test harnesses are "full-fat" iOS apps, so they can't be provided as releases, unless I create an App Store app for each one.

They need to be built and run. A couple are Mac apps, but the whole deal with them, is that they are test harnesses, so divorcing them from the IDE is sort of negating their purpose. They are meant to help other Apple developers to understand and use the packages the apps are associated with.

qwertytyyuu•1d ago
Ah I remember being able to do this with the iPhone 6s
hn_throwaway_99•1d ago
I think this is neat, but only in a Rube Goldberg machine sort of way. The instructions are:

1. Open the scale

2. Rest your finger on the trackpad

3. While mainting finger contact, put your object on the trackpad

4. Try and put as little pressure on the trackpad while still maintaining contact. This is the weight of your object

That is, the pressure sensors only work if it detects capacitance, so you need to be touching the track pad (but not too much!!) while weighing something.

linux2647•1d ago
Sometimes you can get capacitance to be detected if you hover your finger just millimeters over the trackpad
whycome•1d ago
Can’t you get capacitance with a wet sponge? Like your typical dish cellulose sponge. You could make a small platform?
asimovDev•1d ago
I remember drawing on my old iPad back in the day by shoving a wet q-tip into a BIC pen and using it as a stylus. I am sure something similar could be rigged here

It's the reason why I love Note and S Ultra phones - the stylus. I'm using it now.

doubled112•1d ago
The recipe was on your phone/tablet and there was no way you were taking your gloves off?
dotancohen•1d ago
Nice. No, I preemptively armed myself with a carrot before taking the dog for a walk in cold weather.

I only had a non-stylus smartphone for a year and a half before whimpering back to the Note series. It's what keeps me in the Samsung sphere of influence.

acct-litter-al•1d ago
I once put some aluminum duct tape completely over the touch pad of an old laptop to see what would happen. Turns out it induced enough "eddy currents" to make the mouse move around the screen without me touching it--in a way, visualizing the currents!

I connected the foil to ground using a small strip of the tape to the ground metal of a USB port on the side and it disabled the touch pad.

acct-litter-al•1d ago
Looking back, it would have been interesting to code up a program to record the movement of the mouse as a trail of pixels...
KeplerBoy•14h ago
If you ever want to do this keep in mind to reconfigure the mouse as a digital pointing device (tablet like), otherwise the mouse acceleration will mess up your position measurement.

pmxi•1d ago
This is clever! and potentially useful too.

Have you done any testing to determine how precise and accurate this is? I suspect their must be a lot of variance between laptops, since this isn’t an intended use case.

mschuster91•1d ago
> I suspect their must be a lot of variance between laptops, since this isn’t an intended use case.

Yeah and so it is for ordinary strain gauges aka load cells. You can either use a 2 point calibration (aka no load followed by known load) or if you want more precision a 3 point calibration.

[1] https://en.wikipedia.org/wiki/Load_cell

cluckindan•1d ago
I would assume Apple hardware comes precalibrated. Homogeneity is everything for their product lines, down to individual calibration of screens and audio hardware. It would be weird to get a new laptop and have its trackpad feel different.
hbn•1d ago
They have a setting for adjusting the pressure needed to activate a click.

I wonder if that affects this app at all.

alden5•22h ago
The app isn't accurate at all, magic 8-ball of scales, anything you put on the trackpad it'll settle on a weight and give you a number but it'll be random. The app will accurately tell you how much force you're applying with a finger but when putting something else on it'll settle on a random number
DonHopkins•1d ago

qoez•1d ago
Apparantely on safari there's touch strength so this should be possible to make for the web too, cool
ashertrockman•1d ago
Somebody could use this as a starting point. http://touchscale.co/ You'd have to collect new data on touch strength vs. weight to get the regression parameters.

(If you do this, let me know and I can add it to the site above, and then we can both delight in the surprisingly large amount of unmonetizable traffic it gets.)

I showed the data to Tesla service and they (grumbled and) readjusted the trunk gate. The problem disappeared.
dtgriscom•1d ago
I wrote that software, called SeisMac. Someone figured out the Apple-private API for the Sudden Motion Sensor that parks your laptop's hard drive if it detects free-fall. Working from that, I wrote a free app that used the API to show three-axis acceleration graphs. I was proudest of the calibration utility, which had you tip your laptop on its side (with properly rotated dialogs!), and then on its screen.

People would send me recordings from all over the world (e.g. on a ship in the Drake Passage showing enormous surges). It was a lot of fun, and I even got an educational grant to improve it.

Big bummer when Apple switched to solid-state drives (well, a bummer for my one small reason...)

ivanjermakov•1d ago
> TrackWeight utilizes the Open Multi-Touch Support library by Takuto Nakamura to gain private access to all mouse and trackpad events on macOS. This library provides detailed touch data including pressure readings that are normally inaccessible to standard applications.

How can something be available as a library but not as a native interface? Swift does not expose that API?

bri3d•1d ago
Mac OS has "Private Frameworks" - shared libraries that are used by the system but don't ship with headers by default. It's trivial to produce these headers from the libraries, and then make wrappers for them like OpenMultitouchSupport which is a wrapper for MultitouchSupport.framework.
anxman•1d ago
But just to note, I believe you can't pass Gatekeeper/Notary if you use these APIs so it's not possible to sign the app

It goes in gram increments and my laptop was able to read 7300g pressing as hard as i could, which I was surprised it would be designed to read that high, might go up to 10kg but I don't want to crack my trackpad lol. The actual measurements though are extremely unreliable. I've found it can't reliably measure anything, measuring a roll of tape gave me measurements from 70g to 700g, it always settled on a number but was different every time. Maybe the underlying data is more accurate but this API is definitely just designed for outputting the force of a finger. M1 MBP for reference

What's the weight range it can handle? no mention of it and I don't want to dig through code

Could it be used to provide gait analysis for your pet mouse?

How does one come up with this idea?

I love this, such a creative hack, and the wonderful irony that it only works when one has their finger on the scale.

I was a bit frustrated that the expected precision wasn’t on the main summary screen.

Does anyone know?

OT, but this is what i love about apple laptop. They care about small detail, the detail that won't be on spec sheet for advertising.

Like their laptop speaker is superior to any other machine, even premium laptop like xps or surface won't even come close. Or their huge trackpad but still accurate.

I wish other manufacturers copy this from Apple.

If you are backpacking with your Macbook, this saves you from also needing to pack a kitchen scale.
