Researchers have developed SenWorld, a novel digital-twin simulation designed to generate context-rich evaluation data for smartphone personal assistants. This physically grounded, deterministic system creates privacy-safe, reproducible datasets by archiving all observable signals and labeling evaluation cases by referencing existing records, rather than relying on post-hoc annotation or LLM judges. Initial evaluations with 16 personas in Beijing demonstrated that SenWorld's generated data closely matches real-user benchmarks in category distribution and daily communication rhythms, successfully identifying 78 failures in a production assistant, primarily related to call and SMS records.
