P1: Smart Phone Interaction
Workaround
Patent Claim…
Claim 1. A computer-implemented method of
controlling a portable electronic device comprising
a touch-sensitive display (408, 1014), comprising:
• detecting contact with the touch-sensitive
display while the device is in a user-interface
lock state;
• transitioning the device to a user-interface
unlock state if the detected contact
corresponds to a predefined gesture;
• and maintaining the device in the userinterface lock state if the detected contact
does not correspond to the predefined
gesture;
characterized by
• moving an unlock image along a predefined
displayed path on the touch-sensitive display
in accordance with the contact,
• wherein the unlock image is a graphical,
interactive user-interface object with which a
user interacts in order to unlock the device.

Main Idea
Sketch, design, implement and document via a
portfolio an interface that provides an alternative
way to unlock a mobile phone equipped with a
multi-touch display and sensors.
• Develop two techniques: one with
gestural/multi-touch input; one with sensor input
(for one handed use)
• Use animation to provide feedback
• Goodness: should avoid accidental activation &
that it can be used as a weak password
Deliverables
• 10 competing design sketches, 10 sketch
refinements
• Implemented WPF application
• Web portfolio
• Visual project summary
• Demonstration
For Monday
• Prepare 10 different ideas in your sketchbook
regarding
• Bring your sketchbook to class, as it will be
graded first thing in the morning.
