Patent attributes
Modifying a tether linked to a cursor based on depth volatility of the cursor is disclosed. Multiple displays show a three-dimensional image that seems to be at the same real world location regardless of the location of the display. One person operates a cursor in the three-dimensional image. Volatility of depth of the cursor from the viewpoint of the cursor operator is tracked. The appearance of the tether is changed in other displays in response to the depth volatility. The tether may include a line from the cursor towards the cursor operator. The tether is not necessarily displayed all of the time so as to not obscure the view of the three-dimensional image. When there is not any depth volatility for some time, the tether is not displayed. In response to high depth volatility, the tether may be displayed as a long line from the cursor.
