Abstract

A computing device including a multi-touch surface, and a method of operation thereof are described. The method comprises: detecting a customer'"'"'s hand placed palm downwards on the multi-touch surface and detecting the customer'"'"'s hand pivoting upwards from the detected palm downwards position so that an edge of the hand is placed on the multi-touch surface. The method also comprises displaying a private interaction window located adjacent to, and on the palm side of, the customer'"'"'s hand; and communicating private data on the private interaction window. The private interaction window is dimensioned to be shielded by the customer'"'"'s hand.

Claims

1. A method of operating a computing device including a multi-touch surface, the method comprising:

detecting a customer'"'"'s first one-handed gesture indicative of a privacy request, the first one-handed gesture including placing the palm side of one hand downwards on the multi-touch surface and then pivoting the one hand upwards from the palm side downwards position on the multi-touch surface to a palm edge downwards position on the multi-touch surface;

in response to the customer'"'"'s first one-handed gesture indicative of a privacy request, displaying a private interaction window located adjacent to, and on the palm side of the one hand, the window being dimensioned to be shielded by the one hand;

communicating private data on the private interaction window while the window is being shielded by the one hand to allow the customer to interact with the private data on the private interaction window in privacy; and

detecting a customer'"'"'s second one-handed gesture to cancel the privacy request, the second one-handed gesture including returning the palm of the one hand to the palm side downwards position on the multi-touch surface.

2. The method of claim 1, further comprising:

detecting dimensions of the one hand based upon the degree of curl of the fingers of the one hand as the one hand is being pivoted upwards from the palm side downwards position on the multi-touch surface to the palm edge downwards position on the multi-touch surface.

3. A method of operating a computing device including a multi-touch surface, the method comprising:

detecting a customer'"'"'s first one-handed gesture indicative of a privacy request, the first one-handed gesture including placing the palm side of one hand downwards on the multi-touch surface and then pivoting the one hand upwards from the palm side downwards position on the multi-touch surface to a palm edge downwards position on the multi-touch surface;

in response to the customer'"'"'s first one-handed gesture indicative of a privacy request, displaying a private interaction window located adjacent to, and on the palm side of the one hand, the window being dimensioned to be shielded by the one hand;

communicating private data on the private interaction window while the window is being shielded by the one hand to allow the customer to interact with the private data on the private interaction window in privacy;

detecting a customer'"'"'s second one-handed gesture to cancel the privacy request, the second one-handed gesture including returning the palm of the one hand to the palm side downwards position on the multi-touch surface; and

detecting dimensions of the one hand based upon the degree of curl of the fingers of the one hand as the one hand is being pivoted upwards from the palm side downwards position on the multi-touch surface to the palm edge downwards position on the multi-touch surface

changing size of the private interaction window based upon detected dimensions of the one hand.

4. A method of operating a computing device including a multi-touch surface, the method comprising:

detecting a customer'"'"'s first one-handed gesture indicative of a privacy request, the first one-handed gesture including placing the palm side of one hand downwards on the multi-touch surface and then pivoting the one hand upwards from the palm side downwards position on the multi-touch surface to a palm edge downwards position on the multi-touch surface;

in response to the customer'"'"'s first one-handed gesture indicative of a privacy request, displaying a private interaction window located adjacent to, and on the palm side of the one hand, the window being dimensioned to be shielded by the one hand;

communicating private data on the private interaction window while the window is being shielded by the one hand to allow the customer to interact with the private data on the private interaction window in privacy; and

detecting a customer'"'"'s second one-handed gesture to close the private interaction window, the second one-handed gesture including returning the palm of the one hand to the palm side downwards position on the multi-touch surface.

5. The method of claim 4, further comprising:

detecting dimensions of the one hand based upon the degree of curl of the fingers of the one hand as the one hand is being pivoted upwards from the palm side downwards position on the multi-touch surface to the palm edge downwards position on the multi-touch surface.

6. A method of operating a computing device including a multi-touch surface, the method comprising:

detecting a customer'"'"'s first one-handed gesture indicative of a privacy request, the first one-handed gesture including placing the palm side of one hand downwards on the multi-touch surface and then pivoting the one hand upwards from the palm side downwards position on the multi-touch surface to a palm edge downwards position on the multi-touch surface;

in response to the customer'"'"'s first one-handed gesture indicative of a privacy request, displaying a private interaction window located adjacent to, and on the palm side of the one hand, the window being dimensioned to be shielded by the one hand;

communicating private data on the private interaction window while the window is being shielded by the one hand to allow the customer to interact with the private data on the private interaction window in privacy;

detecting a customer'"'"'s second one-handed gesture to close the private interaction window, the second one-handed gesture including returning the palm of the one hand to the palm side downwards position on the multi-touch surface; and

detecting dimensions of the one hand based upon the degree of curl of the fingers of the one hand as the one hand is being pivoted upwards from the palm side downwards position on the multi-touch surface to the palm edge downwards position on the multi-touch surface

changing size of the private interaction window based upon detected dimensions of the one hand.
