Microsoft’s Yusuf Medhi explains: “This is something I haven’t seen us show yet. There aren’t any swiping gestures for UI navigation like what was shown at the reveal. You start with an open palm at about chest level for a hand to show up, waving is gone. To scroll left or right, you “grab” the virtual dashboard pane and form a fist. Then you can move your fist left and right. Very much like click and drag in maps. Selection is done by pressing. Hence the large metro square and rectangle designs. Makes pressing virtual buttons easier,” the developer said.
"For selections and pressing buttons, a forward push with an open palm is the equivalent of a left-click on the button."
