It seems like Apple has taken note of what its users need and is bringing USB mouse support to the iPad. MacRumours notes that Federico Viticci, MacStories' editor-in-chief, slipped out the scoop in an episode of the Connected podcast. The same information was iterated by the noted developer Steve Toughton-Smith, who tweeted, “Despite having so much context as to what’s coming at WWDC, or perhaps because of it, this is the most excited I’ve been about a WWDC in a decade. There are so many hugely transformative things on the horizon — iOS apps on the Mac, iPad windowing & mouse support, iTunes breakup…”
"What I heard is without adapters, you will be able to use any USB mouse on your iPad, but as an accessibility device," said Viticci. "The iPad Pro has a USB-C port, so just plug in a USB mouse and if you have physical impairments, if you have any other kinds of motor impairments, just use a USB mouse in accessibility mode." Seems like Apple will be introducing the option of using a USB mouse as an accessibility feature but the option, if announced, will certainly help iPad consumers work better on the device and bridge the gap between a tablet and a laptop.
It has been possible to use an accessory like a joystick or a trackball to control an iPad or an iPhone via Apple's AssistiveTouch accessibility feature. However, the new direct support for a USB mouse will most likely eliminate the need for an adapter or any other similar kind of hardware. Additionally, Toughton-Smith notes that this won’t be the first time Apple is introducing a feature under accessibility services and all users will get to switch the feature on from settings. He adds that iOS might bring a “small circle or dot" to replace a mouse’s cursor.
