Shareable Device Session Management via User Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for device sharing, such as smart devices and consumer electronics, face challenges in seamlessly switching between users, often requiring manual login and logout, leading to issues like unauthorized access to personal information and frustration due to automatic logout during inactivity or inability to maintain sessions in unsupervised environments.
Innovation Solution
Implementing a device sharing module that uses sensors to detect user intent and authenticate users without manual input, allowing for temporary access to personalized content and sessions, while also ending sessions based on user conditions to secure data and enable seamless switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual login and logout is required for device sharing, then user security and access control is improved, but user convenience and ease of operation deteriorates
Solution Approach 1:
The system automatically detects user presence through sensors and performs authentication without manual intervention. The device self-manages login and logout processes by monitoring user presence, eliminating the need for users to manually initiate these actions while maintaining security through automated credential verification.
Solution Approach 2:
The patent replaces manual mechanical interactions (typing passwords, pressing buttons) with sensor-based detection systems. Optical sensors, proximity sensors, and other detection mechanisms automatically identify users and trigger authentication processes, substituting physical user actions with automated sensing and processing.
2Reliability
If automatic logout is implemented after inactivity, then security is improved, but user experience and session continuity deteriorates
Solution Approach 1:
The system continuously monitors user presence through sensors and provides real-time feedback by adjusting session status. When a user is detected as absent, the system automatically ends the session; when presence is detected, sessions are automatically restored or extended, creating a dynamic response that adapts to actual usage conditions rather than relying on fixed time-based inactivity thresholds.
Solution Approach 2:
The session management system transitions from static time-based logout rules to dynamic presence-based control. Session duration and status are continuously adjusted based on real-time sensor data about user presence, allowing sessions to extend or terminate automatically according to actual user needs rather than predetermined time limits.
3Ease of operation
If device sharing without personalization is provided, then ease of access is improved, but user experience and information security deteriorates
Solution Approach 1:
The system pre-stores authentication credentials and user profiles in secure memory before actual use. When a user approaches the device, the system quickly retrieves and verifies the appropriate credentials from pre-configured data, enabling immediate secure access without requiring users to manually input information at the moment of use.
Solution Approach 2:
The patent divides the device access system into separate functional modules: sensor detection, credential retrieval, authentication verification, and session management. Each module handles a specific aspect of the access process, allowing the system to simultaneously provide easy access through automated detection while maintaining security through dedicated verification procedures.
4Ease of operation
If sensor-based automatic authentication is implemented, then ease of operation is improved, but device complexity and cost increases
Solution Approach 1:
The system employs multi-functional sensor modules that can detect various types of user presence and characteristics. These sensors serve multiple purposes: identifying user approach, verifying user identity, and tracking user engagement, thereby reducing the need for separate specialized components and minimizing overall system complexity despite the advanced functionality provided.

AI summary
In aspects of shareable devices, a shareable device implements a device sharing module that can maintain an interactive session of a user on the shareable device. The shareable device can detect that the user has moved away from the shareable device during the interactive session, and obscure personalized content associated with the user who has moved away from the shareable device. The device sharing module is implemented to detect, without user input, a user condition indicative of an intent to end or share the interactive session. The device sharing module can determine a status of an executing application associated with the interactive session of the user. The device sharing module can then end or share the interactive session based on the detected user condition and the determined status of the application.
