Navigational Mnemonics for Cross-Device Activity Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in tracking and accessing their activities across multiple computer devices due to limited functionality in existing systems, which makes it difficult to resume activities like web browsing, file access, or media playback without remembering specific details such as URLs or device locations.
Innovation Solution
A system that collects, organizes, and displays user activity information across multiple devices using navigational mnemonics, allowing users to easily locate relevant activities by associating them with memorable events, people, or locations, and provides mechanisms for creating and selecting activity records and navigational mnemonics based on relevance criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional activity tracking methods (recent files list, browser history) are used, then some activity information is available, but the information is limited to single applications and intermixed with voluminous irrelevant data
Solution Approach 1:
The patent segments activity information by associating it with distinct navigational mnemonics (people, places, things, events). Instead of presenting a single undifferentiated list of recent activities, the system divides activities into categories based on their contextual associations, allowing users to navigate to specific types of activities more efficiently.
Solution Approach 2:
The patent introduces navigational mnemonics as intermediary elements between users and activity information. These mnemonics act as mediators that users can recall to access associated activities, replacing the need to directly search through voluminous activity lists. The mnemonic serves as a cognitive bridge that simplifies the retrieval process.
2Adaptability or versatility
If comprehensive activity tracking across multiple devices is implemented, then activity information becomes more complete, but the complexity of managing and accessing this information increases
Solution Approach 1:
The patent implements a universal activity tracking system that works across multiple device types (desktop, mobile, tablet) using consistent navigational mnemonic concepts. The same mnemonic-based interface and data structure are applied universally across all devices, allowing users to access and manage activities from any device without learning device-specific complexities.
Solution Approach 2:
The patent changes the organizational parameter of activity storage from device-centric to mnemonic-centric. Instead of organizing activities by device or application, the system reorganizes them around navigational mnemonics, which are device-agnostic cognitive anchors. This parameter change simplifies cross-device access while maintaining comprehensive tracking capabilities.
3Loss of information
If detailed activity records are maintained, then information completeness improves, but the time required to search through and locate specific activities increases
Solution Approach 1:
The patent applies preliminary action by pre-associating activities with navigational mnemonics at the time of activity creation or completion. This pre-establishment of contextual associations means that when users need to retrieve activities, they can directly access them through recalled mnemonics without performing time-consuming searches through detailed activity records.
4Ease of operation
If traditional history or recent files functionality is used, then basic navigation is provided, but users cannot easily resume activities without remembering specific details like URLs or device locations
Solution Approach 1:
The patent uses navigational mnemonics as intermediary cognitive anchors that users can recall without needing to remember specific activity details like URLs or device locations. When users need to resume an activity, they retrieve it through the mnemonic association rather than directly recalling technical identifiers, significantly reducing the memory burden.
Data Source
AI summary
Techniques are described for obtaining user activity information and navigational mnemonic information. The activity information and navigational mnemonic information can be used to control information presented in displays in a manner that can assist a user in locating an activity using displayed navigational mnemonics. User activity information can include an application identifier and a content identifier. Navigational mnemonic information can include a resource identifier and a relevance identifier. A user can search for activities based on a relationship between a navigational mnemonic and an activity, such as a temporal relationship. Applications can register both activity information and navigational mnemonic information through an interface, and a navigational mnemonic feed service can provide navigation mnemonics that are not directly related to user activity on user computer devices.
