Abstract: A method and a system for providing a roughness haptic sense of a virtual object by using space-time encoding are provided. The method for providing a roughness haptic sense of a virtual object may comprise the steps of: displaying virtual objects to a user; tracking the position of the user's hand; predicting a virtual object, which is most likely to collide with the hand, among the virtual objects; and when the hand touches a haptic sense providing device, controlling the haptic sense providing device on the basis of the surface roughness of the predicted virtual object to feed back a roughness haptic sense to the user.

Abstract: A method may include identifying, from a set of applications, a subset of the set of applications, each application from the subset of the set of applications being predicted, by a computing device, to be selected by a user. The method may also include outputting a graphical user interface that includes: a plurality of application icons representing the set of applications and positioned around at least a portion of a perimeter of the graphical user interface; and a plurality of prediction icons positioned within an interior of the graphical user interface and representing the subset of the set of applications. The position of a particular prediction icon representing a particular application may be based on a position of a particular application icon representing the particular application. The method may further include executing an action associated with the particular prediction icon or the one of the plurality of application icons.
