In some instances, however, such stimuli can interfere with the user's ability to accurately and / or safely manipulate the controller that provides such haptic feedback.
For example, force feedback on a controller that is used to operate a crane can result in unintended movements of the user's hand, which may, in turn, move the controller to an unintended position, thereby causing an accident.
Similar results occur in video games when utilizing a force feedback joystick to control game play; however, this resulting loss of control has less catastrophic consequences.
Hence, in some instances, vibration feedback and especially force feedback may reduce safety of operation of a controller that integrates such haptic feedback mechanisms.
Such concerns are the reason why force feedback of tool tip forces are not currently permitted in robotically enabled surgical applications.

Embodiment Construction
[0074]Embodiments of the present disclosure provide devices, systems, and methods for displaying information about direction of movement, speed, resistive force experienced, other aspects of movement for an object, or combinations thereof. The device can also be used to display or feedback a wide variety of information that has magnitude and / or direction associated with it (e.g., temperature, pressure, volume, proximity, other information, or combinations thereof) or give guidance about where a person should move (e.g., to push forward on an aircraft control stick to prevent stall from occurring). More specifically, the present disclosure provides a shear display device that can generate skin shear or skin stretch with one or more tactors moving in a two- or three-dimensional space. The tactors (or contactors) are the moving contacts between the shear display device and the user's skin, and the terms shear display, shear feedback, skin stretch, and skin stretch feedback are used int...

Abstract
Embodiments of the present disclosure relate devices, systems, methods, and for displaying information about the direction and magnitude of position, movement, and / or resistive force experienced for an object. The present disclosure also provides a shear display device that can generate skin shear with one or more tactors, each moving in a two- or three-dimensional space. The movement of the tactors can represent to a user various information about an object.
