Communication Intent Verification for Accidental Call Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unintentional inputs on communication devices, such as smartphones, often lead to unexpected and unwanted communications due to accidental brushes, taps, or bumps, especially when the device is in a pocket or bag, triggering actions like phone calls or messages.
Innovation Solution
A communication device with a processor that receives a request to initiate a communication, determines if it is unlikely, and requires a confirmation before sending, using various input devices and sensors to verify user intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device requires confirmation for communication requests, then accidental transmissions are reduced, but the communication speed and user experience are degraded
Solution Approach 1:
The system dynamically adjusts the confirmation requirement based on detected context. When the device is determined to be in a pocket or bag (inferred from sensor data patterns), confirmation is mandatory. When the device is in normal usage conditions, confirmation may be waived, thus adapting the confirmation behavior to the situation rather than applying a static rule.
Solution Approach 2:
The system changes the parameter of confirmation requirement based on detected context. By analyzing sensor data (accelerometer, gyroscope, proximity sensor readings) to infer device location and usage context, the system adjusts whether confirmation is needed, effectively changing the confirmation parameter dynamically based on environmental conditions.
2Measurement precision
If the device uses multiple input devices and sensors to verify intent, then the accuracy of intent detection is improved, but the device complexity increases
Solution Approach 1:
The system uses existing multi-functional sensors already present in the device for other purposes (accelerometer for screen orientation, gyroscope for rotation, proximity sensor for call detection) and repurposes them for intent verification. This avoids adding dedicated hardware while achieving accurate intent detection through multi-sensor fusion.
Solution Approach 2:
The device uses its own existing sensors and processing capabilities to verify user intent, rather than requiring external verification mechanisms. The processor analyzes data from existing sensors (accelerometer, gyroscope, proximity sensor) to independently determine whether a touch was intentional, making the system self-verifying without additional complexity.

AI summary
Methods, communication devices, and computer-readable medium are disclosed for preventing unintentional outgoing communications initiated from a communication device. In one embodiment, the method includes receiving a request via a first input device to initiate a communication to a contact, determining whether the request is unlikely, receiving a confirmation that the request is intentional responsive to determining the request is unlikely, and sending the communication to the contact responsive to receiving the confirmation.
