Hand waving

But [View in browser]( [Bloomberg]( [by Austin Carr]( Hey y’all, it’s Austin Carr in Boston. Touchless controls are bringing all kinds of hand waving and finger jabbing to new tech products. But first... Three things you need to know today: • Questions remain as to why [Sam Altman was fired]( • Foxconn’s founder [dropped out of Taiwan presidential race]( • GM’s Cruise is [resuming service]( Learning curve A buzzy (and sometimes ridiculed) new gadget from startup Humane Inc. will require customers to learn a novel set of gestures to interact with its so-called [Ai Pin](. The $700 lapel wearable, which allows users to access artificial intelligence services without a screen, includes a tiny projector that displays a laser interface on your held-up palm. Tilting your hand slightly will scroll through projected buttons while tapping your thumb and index finger together is the equivalent of a click. The startup isn’t the only company embracing floating gestures. Apple Inc. and Meta Platforms Inc. are likewise betting that reading and tracking the movements of hands and fingers could replace the tactility of a keyboard, mouse or touchscreen. But over a decade of failed attempts suggests humans are unconvinced by the hand waving. The closest anyone has come was Microsoft Corp.’s [now-discontinued Kinect](, the Xbox add-on released in 2010 that used motion and depth sensors in lieu of traditional game controllers. Players could swat objects on screen by swinging their arms and have their avatars leap by jumping in real life. The product was a hit at first but proved to be a fad. The recognition system was glitchy and imprecise, partly because there was no haptic feedback to indicate the Kinect was keeping pace with your movements. Phone makers solved this by adding a subtle buzz to simulate the sensation of a button press. But miming [driving a car with empty hands]( was no match for the vibrations of an Xbox controller or steering wheel accessory. A few years later, Leap Motion Inc., the once-promising startup that [vowed to replace]( the mouse with gesture sensors, ran into similar problems. The system wasn’t really that much more convenient than dragging around a mouse, and reviewers found it [physically exhausting]( to keep their hands raised for basic tasks. Another issue with air gestures is that they historically haven’t been particularly useful. In 2019 Google put motion sensing in its Pixel smartphones, but the features were uninspired. For example, you could wave your hand over the phone to dismiss an unwanted call. Similar gestures still exist in Google’s Nest Hub, the countertop tablet, and I’ve found them awkward and superfluous. To snooze an alarm, you have to extend your palm toward the screen, like shoving a ghost. It’s hit or miss, and I rarely, if ever, use it; tapping or using a voice command is much faster. Apple and Meta are trying to find ways to make gestures feel or at least look more intuitive. In a [recent developer tutorial]( for [Apple’s Vision Pro mixed-reality headset](, Apple interface designer Eugene Krivoruchko talked up the “need to compensate for the missing sensory information” by replicating tangible interactions. When a finger hovers over a digital key or menu option, its lighting will adjust as a “proximity cue,” and a sound effect will immediately play when it’s clicked. Maybe the biggest hurdle for users is the guesswork involved. Each company is crafting its own variations of swipes and pinches that will carry a learning curve. To pause a song on Humane’s Ai Pin, users must do the finger-thumb tap once; meanwhile, Apple last month implemented a [double tap for that same action]( on the Apple Watch. Depending on the product, clenching your fist can quit to the home screen, return to the previous app or even [take a screenshot](. Until these new-age devices figure out a consistent way to use them, I’ll stick to pressing buttons. —[Austin Carr](mailto:acarr54@bloomberg.net) The big story The EU hit Russia with sanctions to stop the flow of propaganda after Russia invaded Ukraine, but [mirror websites are still spreading]( disinformation two years later.
