We've learned to be highly suspicious that the GPS, camera and microphone in our smartphones can be used to track our every move, listen into our conversations and watch our most intimate moments. But what about the act of tapping and swiping our screens? Can that be used by a bad actor? Researchers from CSIRO's Data 61 have found just that.

Android: In lieu of an old-fashioned rewind button, video players have opted for skip buttons that let you jump back or forward a bit. YouTube on Android is jumping on that bandwagon with the latest update.

If you own a MacBook, you're likely well aware of how scrolling and right-clicking work on the trackpad, but you may not know how to invoke Quick Look, Notification Center, or Exposè. Whether you're new to macOS or you just never bothered to learn them, these gestures can make your life a little simpler.

iOS: If you're on the move a lot, controlling the music on your iPhone by tapping buttons isn't always easy. Swysh is an iPhone app that lets you use simple motion gestures to switch between songs.

Android: Google's smart keyboard does its best to learn the way you type, but it occasionally gets it wrong. In the latest version, you can now easily remove words from your user dictionary with a simple long-press and drag.

Mac: The three-finger gesture that allows you to drag windows around without a click has been in OS X for a while, but in both Yosemite and El Capitan, the setting to enable it was moved. Now, it's over in the Accessibility options.

Android: Controlling your phone while you drive isn't very easy. Google Now and other voice assistants can do a lot, but Drivemode takes the idea a step further. It incorporates many of those voice commands with a simple, gesture and colour-based interface that's powerful without being distracting.

If you have a precision touchpad on your laptop, you also have a few new gestures you can use in Windows 10. You can quickly get to task view, alt+tab or show the desktop using three-finger gestures.

Microsoft had rolled out a new test build for Windows 10. As well as the expected bug fixes (and new bugs), there are some new features, including some nifty three-finger gestures for touchpads.

Android: BrainWave controls your favourite music player app and controls it with the wave of a hand. Just select your music player and use the three gesture options to control it.

When you're typing in the calculator that comes with iOS 8, and you make a mistake, you probably get frustrated at the lack of a backspace button. However, you can delete individual digits as you type -- the function is just hidden behind a gesture.

Ever need to copy, share or speak text on iOS? Of course you do. Here are four different shortcuts that can make the process quick and easy.

Android: With one swipe, Pie Control will give you access to your Android device's settings, favourite apps, menu buttons, app drawer and more.

iOS 8: SwiftKey, our favourite Android keyboard, just launched for iOS 8 devices, and it's bringing its best features along for the ride. Gesture typing, predictive text that learns from how you type and cloud-connected settings that you can use on multiple devices are just a few of what's available in the iOS version.

Android: When you see a link, you might not always want to do the same action when you tap it. LinkSwipe lets you set five presets so that you can tap and swipe in different directions to perform different actions.

Android: Seasoned SwiftKey users make typing look easy. SwiftKey houses a heat map feature that shows you where your touch patterns are -- and where your most common mistakes might be made.

Android: Android's Share menu is a little clunky. Instead of scrolling to the app you want, TapPath lets you use single, double and triple taps to share links to your most frequent apps.

Android: When you need to make a call, Slide Dial provides access with a single swipe, from anywhere on your phone. There's no need to switch to the home screen and then the dialler, or use the task manager. You can call up the dial pad from any app.

1Password is a great tool for remembering your passwords. Here's a little shortcut for the mobile app you might not know: swipe to the right over a password to copy it.
