Abstract: We introduce a haptic mousewheel as a platform for design exploration of haptic conviction widgets. Conviction is how strongly one wants to do something, or how strongly one desires a parameter to be as it is. Using the haptic mousewheel, the widgets allow users to communicate conviction using force, where greater conviction requires greater force. These widgets include buttons that take varying amounts of force to click, a trash can that requires overcoming force to delete files, an instant message client that requires more force to communicate a stronger emotion, and widgets that allow parameters to be locked using force.
