Patent Images
1. A method of automatic orientation of an item having an orientation vector τ
- , towards a user operating in a surface computing environment having a multi-touch capable display, the method comprises the steps of;
Identifying a user hand touch or gesture affected by the user on the display, at a location associated with an item;
responsive to the hand touch or gesture, determining a hand orientation vector η
;
orienting the item to the user by aligning the item in a predetermined relation between the hand orientation vector η and
the orientation vector τ
of the item.

9. A method of estimating a user location relative to a multi-touch capable display, the method comprises the steps of:
-
Identifying a user hand touch on the display, the touch comprising at least a plurality of touch points made by simultaneous touch of a plurality of fingers; identifying a convergence point associated with the user palm attached to the plurality of fingers; calculating a plurality of vectors from the convergence point to the corresponding plurality of the fingers; summing the plurality of vectors to receive a user direction approximating the location of the user relative to the convergence point. - View Dependent Claims (10, 11)
