Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing machines face challenges in accurately determining user proximity for processing input commands, leading to potential security issues and inefficiencies in power management, as existing systems struggle to differentiate between authorized and unauthorized inputs and manage power states effectively.
Innovation Solution
A system that utilizes sensors, such as motion, proximity, and image capturing devices, in conjunction with an input application to determine user proximity by scanning the environment, configuring input devices to accept or reject commands based on predefined distances and shapes, and managing power states accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the computing machine processes all input commands without verification, then the processing speed is maintained, but security risks increase due to unauthorized inputs
Solution Approach 1:
The system performs preliminary detection of user proximity and identity verification through sensors (camera, microphone, motion sensors) before processing input commands. This preliminary action ensures that only authorized users can trigger input processing, thereby maintaining security without significantly impacting overall processing speed for authenticated users
2Speed
If the computing machine remains in active power state continuously, then input response time is fast, but power consumption increases
Solution Approach 1:
The system dynamically adjusts power states based on detected user presence. When sensors detect a user approaching or present, the system transitions to active power states for rapid input processing. When no user is detected, the system enters low-power states. This dynamic adaptation maintains fast response times when needed while reducing power consumption during idle periods
Solution Approach 2:
The system employs periodic sensing to detect user presence rather than continuous monitoring. Sensors are activated at intervals to check for user proximity, allowing the system to maintain low power consumption while still providing timely response when a user arrives. The periodic detection triggers transitions to active states only when necessary
3Measurement precision
If the computing machine uses multiple sensors for user detection, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The system merges multiple sensor types (camera, microphone, motion sensors, proximity sensors) into an integrated user detection system. These sensors work together to detect user presence, approach, and identity through combined data analysis. By merging sensor functions and processing them through a unified system, the patent achieves high detection accuracy while managing complexity through integration rather than separate independent systems

AI summary
A method for detecting an input command including configuring a sensor to determine whether a user is within a proximity of a computing machine, configuring an input device to detect an input command entered by the user when the user is within the proximity of the computing machine, and transmitting the input command for the computing machine to process.
