Information Handling System Dynamic Friction Touch Device for Touchscreen Interactions

摘要

A rotating body, such as ball, disposed in a totem is selectively engaged and disengaged by a friction element to selectively restrict or allow motion of the totem on a touchscreen display. Engagement of the rotating body maintains a totem position on a touchscreen display, such as to support rotational inputs associated with a rotational user interface or to prevent the totem from sliding off the touchscreen display in response to tilting of the touchscreen display. Disengagement of the rotating body releases the totem to slide across the touchscreen display, such as to make inputs at a linear user interface.
