Apple is exploring the possibility of including a biometric heartrate monitor into the palm rest of its new MacBooks, further indication that biometrics are here to stay.
The newly filed patent application describes how a microperforated biosensor in the right palm would shoot tiny beams of light into the skin of your wrist and measure the amount of light reflected back to it. Presumably, this wouldn't be a biometric to use for security, i.e. a replacement for the fingerprint sensor – without any other explanation from the patent, we'd expect the MacBook would use this sensor to track heart rate for health-monitoring reasons.
This is essentially the same kind of biometric sensor in the Apple Watch 6, Samsung Galaxy Watch 4, and the best fitness trackers out there, but it would be the first we've seen something quite like this in a laptop.
It should be noted that patent applications don't mean that such technology is actually going to make its way into MacBooks anytime soon. Apple Insider also notes that what Apple seems to be most interested in is how to fit such a technology into the palm rest and are much less caught up on the details about what kind of sensor is used.
The patent also points out the obvious concern some may have with a pulsating light coming from the palm rest of their MacBook, indicating that a proximity sensor would be used to ensure that measurements are only taken when the user's wrist in fully covering the sensor – so if you're browsing in the dark, you won't get blasted with light searching for heartbeats.
Analysis: biometrics are going to be everywhere, we guess
The utility of this kind of technology is certainly interesting, but I'm not sure this is the best use of this space on a MacBook.
While it's certainly worthwhile giving people important information about their health, there are devices for that if people are so inclined. A MacBook just doesn't seem like one of them.
What's more, that chassis real estate in the palm rests is some pretty precious territory that seems wasted on something like a heartrate monitor. It'd make much more sense to insert something like a stylus pad (akin to that on a graphics tablet) for creative work than a heartrate monitor if you are going to use that space for something other than a straight up palm rest.
