Handheld Device Channel Code Application Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held electronic devices, such as mobile phones, become increasingly complicated as the number of functions grows, making menu selection difficult and time-consuming, leading to user inconvenience and reduced willingness to purchase due to complex operation paths.
Innovation Solution
Implementing a method where hand-held electronic devices use channel codes to simplify application selection, allowing users to 'surf' through channels using input keys to choose desired applications, similar to channel surfing on a TV, thereby simplifying the operation and reducing search time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of functions is increased, then the device becomes more versatile, but the menu becomes too complicated to operate
Solution Approach 1:
The patent segments the application selection process into two levels: a simplified channel selection interface (first level) that presents only channel codes, and a detailed application list interface (second level) that shows full application names and icons. This segmentation allows users to navigate through numerous functions without being overwhelmed by the complete menu structure, thereby maintaining ease of operation while increasing device versatility.
Solution Approach 2:
The patent introduces an intermediary layer (channel code selection interface) between the user and the complete application list. This intermediary layer simplifies the initial selection process by presenting only essential channel codes, and only when needed does it expand to show the full application list. This intermediary mechanism reduces the cognitive load on users while providing access to all functions.
2Adaptability or versatility
If the menu includes all function selection, then all functions are accessible, but the operation becomes difficult and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-organizing applications into channel codes and pre-displaying the simplified channel selection interface before the user needs to access specific applications. This preliminary structuring allows users to quickly navigate to desired functions without searching through the complete application list, thereby reducing search time while maintaining access to all functions.
Solution Approach 2:
The patent implements a dynamic menu structure that can transition between a simplified channel selection view and a detailed application list view based on user interaction. The interface dynamically adapts its complexity level - starting simple for quick navigation and expanding only when necessary, which optimizes both search time and function accessibility.
3Ease of operation
If the menu structure is simplified, then the operation becomes easier, but the user cannot remember and operate the path of some functions
Solution Approach 1:
The patent adds a dimensional layer to the menu structure by introducing channel codes as a first dimension of organization, separate from the traditional hierarchical menu paths. This additional dimension allows users to access functions through a simplified channel code interface while the system maintains complete information about application paths in the background, preventing information loss while simplifying operation.

AI summary
A method of selecting application and a hand-held electronic device are provided. The method of selecting application is used in a hand-held electronic device, wherein the hand-held electronic device is installed with several applications corresponding to several channel codes. The method of selecting application includes the following steps. Firstly, a selecting signal outputted from an input unit of the hand-held electronic device is received for choosing one of the channel codes. Next, the application corresponding to the chosen channel code is driven. Then, the driven application is displayed on a display unit of the hand-held electronic device.
