Portable Device Face Detection Caller ID Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices currently provide insufficient information for users to decide whether to answer incoming calls, as they only display phone numbers, lacking additional data that could identify callers.
Innovation Solution
A portable device method that collects and displays additional data corresponding to caller ID from various sources, including contact lists, call histories, schedules, emails, databases, websites, and social networks, and uses face detection to display this information at predetermined intervals, allowing users to make informed decisions about answering calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only phone number is displayed as caller ID, then device complexity is reduced, but information completeness deteriorates
Solution Approach 1:
The portable device integrates multiple data collection functions into a single system. The controller collects additional data from multiple sources (call history, contact list, schedule, email, website, social network) and displays them unified on one screen, allowing the device to perform both basic caller ID display and comprehensive information gathering functions through a single integrated system
Solution Approach 2:
The device collects and stores additional data about callers in advance before the actual call occurs. By pre-gathering information from call history, contact lists, and other sources, the system prepares comprehensive caller profiles that are immediately available when a call comes in, eliminating the need for real-time data collection during the call
2Loss of information
If additional data is displayed continuously, then information completeness is improved, but energy consumption increases
Solution Approach 1:
The display controller updates additional data at predetermined time intervals rather than continuously. The controller collects and refreshes caller information periodically, displaying updates only when new data is available or at scheduled intervals, which significantly reduces display energy consumption while maintaining information completeness
Solution Approach 2:
The display system dynamically adjusts its behavior based on detected user presence. When a face is detected, the system activates and displays additional data; when no face is detected, the system enters a low-power state. This dynamic adaptation allows the device to provide complete information when needed while conserving energy when the user is absent
3Use of energy by moving object
If face detection is used to trigger display, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The face detection sensor acts as an intermediary between the user and the display system. Rather than continuously monitoring power states or implementing complex power management logic, the system uses the simple binary output of the face detection sensor (face present/absent) to control display activation, effectively mediating between user presence and energy-consuming operations
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
The solution provides users with comprehensive information about incoming calls, enabling them to make informed decisions and preventing missed data by displaying relevant details when the user's face is detected, thereby enhancing the user experience.
Implementation Method 1
detecting a user's face on the portable device
Data Source
AI summary
A portable device includes: a communication unit configured to transmit and receive additional information corresponding to caller ID over a network; a storage unit configured to store the additional information; a sensor unit configured to detect at least one of a face and a gaze of a user; a display unit configured to display the additional information; and a controller configured to: receive an incoming call; detect the face of the user looking at the portable device; and display first additional information on the incoming call when the face is detected, wherein the first additional information is collected according to the caller ID of the incoming call.
