Circle SelectHow it works:To click, circle an object. To double click, circle an object twice.ProsNo clicking or movement caused by itRelatively quick
Cons

Might accidentally select multiple targetsSlide4Slide5
GarageOverview:Uses a queue to remember recently hovered-over, selectable objects.Recently hovered-over objects are stored in the “garage”, near the clock on the Taskbar.A clockwise circle gesture with the mouse will act as a click on the current item in the garage.A counter-clockwise circle gesture with the mouse will act as a “cancel” for the current item, removing it from the queue.Slide6
Garage: Pros and ConsProsNo complex gesturesCircles are very forgiving, do not have to be perfect!Provides visual feedbackConsCould accidentally select/deselect somethingTedious to sift through items in garage when there are manyThoughtsWhat about scrolling? Text selection? Drawing?Slide7
