Motion-Based User Interface for Handheld Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile wireless communications devices face difficulties in user interface management, especially when a user cannot look at the interface for an extended period, necessitating an improved method for inputting commands without visual attention.
Innovation Solution
A mobile wireless communications device equipped with a motion sensor and processor that captures and associates recorded motions with contact records, allowing users to input commands through gestures and populate application fields with corresponding contact data upon motion recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional user interface (contact switches, rocker switches, thumb wheel, touch screen) is used, then the device can process user inputs, but the interface becomes difficult to manage when the user cannot look at it for an extended period
Solution Approach 1:
The patent replaces traditional mechanical and visual user interfaces (switches, touch screens) with a motion recognition system that uses motion sensors to detect and interpret user gestures. This substitution allows users to interact with the device through physical movements rather than visual-manual operations, resolving the contradiction by making the interface operable without visual attention.
Solution Approach 2:
The system captures and stores motion patterns for later automatic recognition and execution. When a user performs a previously recorded gesture, the system automatically retrieves and executes the associated function without requiring visual confirmation or manual navigation, enabling hands-free, eyes-free operation.
2Ease of operation
If motion patterns are assigned to functions (as in GB-A-2347593 and WO-A-2004/082248), then command input can be performed without visual attention, but the system lacks the capability to efficiently populate application fields with contact data
Solution Approach 1:
The system pre-captures and stores motion patterns associated with specific contacts and data fields. When a user performs the recorded gesture, the corresponding contact information is automatically retrieved and populated into the appropriate application fields in advance, eliminating the need for manual data entry and significantly improving productivity.
Solution Approach 2:
The motion recognition system serves multiple functions: it captures user gestures, identifies associated contacts, retrieves contact data, and populates multiple different application fields (email, messaging, scheduling) with a single gesture, making the system universally applicable across different applications and data types.

AI summary
A mobile wireless communications device is arranged to allow for the entry of a motion capture command from a user interface. After receiving such a command, the device generates a recorded motion from output signals from a motion sensor incorporated in the device. A user may then identify a particular contact record through the user interface whereupon the device will associate the contact with the recorded motion.
