Electronic Device Operation Guide Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices provide unnecessary manipulation guidance for users, leading to user confusion and potential mistakes, as they offer guidance for both common and unique functions without distinguishing between the two, resulting in lost trust and increased risk of errors.
Innovation Solution
An electronic device that classifies functions into common and unique categories based on user interaction, providing confirmation messages only for unique functions and switching manipulations, using a database to generate a table that determines when to present guidance based on user actions and previous interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manipulation guidance is provided for all new functions, then the user receives comprehensive assistance, but unnecessary guidance is provided for common functions the user already knows, leading to user confusion and loss of trust
Solution Approach 1:
The patent segments manipulation guidance into two categories: common functions (record, playback, fast forward, rewind) and unique functions (download, video-on-demand). The system selectively provides guidance only for unique functions, avoiding unnecessary guidance for common functions. This segmentation resolves the contradiction by maintaining comprehensive assistance where needed while eliminating redundant information that causes confusion and loss of trust.
2Loss of information
If manipulation guidance is provided for common functions, then the user receives complete information, but the user performs unnecessary manipulations and the burden increases
Solution Approach 1:
The patent extracts and identifies common functions (record, playback, fast forward, rewind) that users already know from using conventional devices. These common functions are excluded from manipulation guidance provision. The system provides guidance only for unique functions not present in conventional devices. This extraction approach eliminates unnecessary information delivery while maintaining complete information provision where actually needed, reducing user burden and time loss.
3Ease of operation
If the device presents guidance for new functions, then the user receives assistance, but the user may overlook important messages due to repeated unnecessary guidance
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different function types. Common functions receive no guidance provision (quality = none), while unique functions receive targeted guidance (quality = high). This localized approach ensures that guidance is concentrated where it is most needed - for novel functions that users cannot infer - while avoiding the harmful effect of repeated unnecessary guidance that causes users to overlook important messages.

AI summary
There is provided an electronic device which presents manipulation guidance to a user as appropriate, depending on whether it is a function that the user can infer the manipulation method or substance of manipulation of.An electronic device operating by switching between a plurality of types of manipulation targets includes: a storage section storing a database containing data of a guidance sentence concerning a switching manipulation for manipulation targets and guidance sentences concerning manipulations of executing functions of the respective manipulation targets; a detection section for detecting a switching of manipulation targets; a table generation section for generating a table based on the database in response to the detected switching of manipulation targets, such that the functions of the manipulation targets are classified in the table each into a common function for manipulation targets before and after a switching manipulation or a unique function; and a determination section for, if a function designated to be executed pertains to the common function, determining that a confirmation message concerning a switching of manipulation targets is to be presented, and if the function designated to be executed pertains to the unique function, determining that confirmation messages concerning the switching and the designated function are to be presented.
