1. A method of securely receiving user input at a computational device, the method comprising:
- detecting user engagement of a user input at a first input zone of the user input;
determining a first data value corresponding to the first input zone;
displaying the first data value to the user via a user output;
detecting user engagement of the user input at a second input zone of the user input;
determining a second data value corresponding to the second input zone;
displaying the second data value to the user via the user output;
determining that the user has disengaged the user input at the second input zone; and
in response to determining that the user has disengaged the user input at the second input zone, conditioning the second data value as input data for the computational device.

Abstract
A computational device having a user interface is disclosed, the user interface enables a user to securely enter data into the computational device. In particular, the user interface may include a user input portion and a user output portion. The user input portion may be partitioned into a number of input zones, each having a data value associated therewith that when engaged by a user causes the data value associated with the engaged input zone to be provided as input to the computational device.

15. A computational device, comprising:
-
a user interface including a user input portion and a user output portion; and instructions configured to detect user engagement of the user input portion at a first input zone, determine a first data value corresponding to the first input zone, cause the first data value to be displayed via the user output portion, detect user engagement of the user input portion at a second input zone, determine a second data value corresponding to the second input zone, cause the second data value to be displayed via the user output portion, determine that the user has disengaged the user input portion at the second input zone, and in response to determining that the user has disengaged the user input portion at the second input zone, condition the second data value as input data for the computational device. - View Dependent Claims (16, 17, 18, 19, 20, 21)
