Abstract
Touch-based input devices, such as a stylus, can provide feedback in the form of shear forces applied to the user. A stylus can produce shear forces that act on a user to provide unique tactile sensations. For example, a shear device can be included at a grip region of a stylus to provide shear sensations at the user's hands (e.g., fingers). The shear forces can be unaligned forces that urge one part of the user's hand in one direction and another part of the user's hand in an opposite direction or that tend to maintain the other part of the user's hand in a stationary location.
