Intelligent Pad User Detection for Personalized Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face low searching efficiency and poor user experience when trying to access preferred information on display devices while lying or sitting on pads due to the vast amount of available data, as existing methods lack effective user identification and preference determination.
Innovation Solution
A method and apparatus that detect and identify users on pads using temperature, pressure, and biological data, determining user preferences based on historical and physiological parameters to transmit specific instructions to display devices for personalized content display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users manually search for preferred information on display devices, then information access is possible, but searching efficiency is low and user experience is poor
Solution Approach 1:
The system automatically identifies users through sensors (temperature, pressure, biological data) and autonomously determines and displays preferred information without requiring manual searching. The intelligent pad detects user presence and characteristics, then the display device automatically presents tailored content, making the system serve itself rather than requiring active user searching.
Solution Approach 2:
The system pre-establishes user profiles with preferred information types and pre-determines what content should be displayed for each user. When a user is detected, the corresponding preferred information is already prepared and immediately displayed, eliminating the need for users to search through vast amounts of data at the moment of need.
2Loss of information
If the display device shows all available information, then information completeness is maintained, but information selection becomes difficult and user experience deteriorates
Solution Approach 1:
Instead of uniformly displaying all information for all users, the system applies local quality by tailoring the displayed information to each specific user's preferences and characteristics. Each user receives a customized information subset based on their profile, making the information both complete for their needs and easily selectable.
Solution Approach 2:
The system pre-sorts and pre-selects information based on user profiles before display. User preferences are established in advance, and when information needs to be displayed, the appropriate content is already filtered and organized according to each user's specific interests, eliminating the overwhelm of choosing from all available information.
3Measurement precision
If the system implements user identification using multiple sensors and parameters, then user identification accuracy is improved, but device complexity increases
Solution Approach 1:
The user identification system is segmented into multiple independent sensing layers (temperature sensing, pressure sensing, biological data sensing) that operate separately but contribute collectively to user identification. Each sensor type handles a specific aspect of detection, and their results are integrated to achieve high accuracy without requiring a single complex identification mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user experience by automatically displaying preferred information without manual selection, improving searching efficiency and convenience by accurately identifying users and tailoring content based on their preferences.
Implementation Method 1
acquiring temperature data of the object; determining whether the temperature data is within a pre-stored temperature range of a human body
Implementation Method 2
acquiring pressure data from a plurality of locations on the pad; determining a shape of the object based on the pressure data; determining a density of the object based on a ratio of the pressure data to the stressed area

AI summary
The disclosure relates to a method and apparatus for controlling a display device. Aspects of the disclosure provide a method controlling a display device. The method includes detecting an object on a pad; determining whether the object is a user; determining an identity of the user when it is determined that the object is the user; determining at least one user preference associated with the user based on the identity of the user; and transmitting, to the display device, at least one instruction to display information associated with the at least one user preference. When determining the identity of the user, the method includes determining that the user is a person.
