Voice Assistant Content Playback Device with Utterable Guide Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may struggle to select objects on a content reproduction apparatus screen, such as TVs or mobile devices, due to hesitation or lack of knowledge on how to select, leading to prolonged display of the same screen or return to a previous screen without proper guidance.
Innovation Solution
The content reproduction apparatus outputs utterable guide information when no selection is made after a certain time or upon specific user input, providing instructions on how to select objects through voice assistant services, including audio and visual cues, to assist users in navigating the available content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the content reproduction apparatus continuously displays the current screen or returns to a previous screen when no object is selected, then the system maintains operational simplicity, but the user experience deteriorates due to lack of guidance and increased confusion
Solution Approach 1:
The system performs preliminary action by proactively detecting when no object is selected and automatically providing guide information before the user becomes confused or gives up. The guide information is output in advance to assist users in making selections, rather than waiting for explicit error conditions or user requests for help.
Solution Approach 2:
Guide information acts as an intermediary element between the content reproduction apparatus and the user. This intermediary provides bridging assistance by explaining what objects are available and how to select them, mediating the interaction when the user is hesitant or unsure about making a selection.
2Device complexity
If the apparatus provides no guidance when objects are not selected, then the interface remains clean and simple, but information completeness deteriorates leaving users uncertain about how to proceed
Solution Approach 1:
The guide information is provided locally and specifically only when needed - that is, when no object is selected on the screen. The guidance appears in the context of the current screen and relates specifically to the objects that should be selected, rather than providing general or unrelated information that would clutter the interface.
Solution Approach 2:
The system proactively provides selection guidance before the user encounters complete confusion or frustration. By detecting the state where no object is selected, the system preemptively outputs guide information to complete the information gap, ensuring users have all necessary information to proceed with selection.
3Productivity
If the system waits for user utterance to provide guidance, then response efficiency is maintained, but user assistance deteriorates due to prolonged hesitation
Solution Approach 1:
The system performs preliminary detection to identify when no object is selected and immediately outputs guide information without requiring the user to waste time formulating a request. This preliminary action reduces the total time users spend on selection tasks by providing assistance at the earliest appropriate moment.
Solution Approach 2:
The system implements continuous feedback by monitoring whether objects are selected and automatically responding with guide information when selection is not detected. This feedback loop ensures users receive timely assistance based on their actual behavior, reducing hesitation time while maintaining efficient system response.

AI summary
A content reproduction apparatus includes an outputter configured to output audio and video, a user interface configured to receive an utterance input from a user, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory. The processor is configured to control the outputter to output a first screen in which one or more objects selectable by the user's utterance are included and a focus is displayed with respect to one of the one or more objects, and, to control the outputter to output utterable guide information for a next selection according to the object corresponding to the focus displayed, when the user does not provide an utterance through the user interface.
