Smart Assistant Local Cache for Low-Latency Device Control

The patent applies preliminary action by pre-generating and storing semantic representations of common user inputs in a local cache on the client device. When a user provides input, the system first checks the local cache for matching semantic representations, allowing immediate processing without waiting for remote server responses. This pre-computation and local storage approach eliminates the latency associated with transmitting and processing every query remotely, while still maintaining the ability to leverage cloud resources for complex or unrecognized inputs.

The patent applies segmentation by dividing the processing workload between local and remote systems. Common, frequently occurring user inputs are identified and their semantic representations are cached locally on the client device. When a user input matches an entry in the local cache, processing is completed locally without involving remote servers. This segments the processing tasks into local (for common queries) and remote (for complex or new queries), significantly reducing network resource usage while maintaining comprehensive query handling capability through the fallback to remote processing when needed.

The patent applies copying by creating and storing simplified semantic representations of user inputs in a local cache on the client device. These semantic representations are compact data structures that capture the essential meaning of common queries without requiring full processing power. The cache stores pre-computed semantic representations that can be quickly matched against user inputs, enabling fast local processing. This copying approach balances the trade-off by implementing a relatively simple cache management system that stores essential semantic information, achieving significant processing speed improvements and network efficiency gains without excessive device complexity.
