TimeSRL uses semantic abstractions from time-series data optimized via reinforcement learning to achieve better cross-dataset generalization than standard ML or LLM baselines in mental health prediction.
AI-authored goals produce higher SMART quality scores but lower psychological ownership, commitment, importance, and goal-directed behavior than self-authored goals, with ownership as the mediating mechanism.
Urban Indians practice health tracking as collective family care, and personal health informatics should be redesigned around agency, elicitation, and engagement to support proactive shared care.
A 9-week mixed-methods study with 12 families found home displays significantly increased mood and goal tracking frequency over smartwatches alone, with multi-device setups accommodating diverse family routines and preferences.
LLM-powered conversational voice sleep diaries achieved higher adherence and richer contextual reports than text-based diaries, with a noted trade-off in structured field completeness.
Extends unsupervised eye contact detection for mobile scenarios, reporting significant performance gains on two datasets and new attention metrics.
Presents an LLM-mediated architecture for continuous adaptation of health dashboards by synthesizing explicit feedback, spatial reorganization, and attention signals via structured prompt engineering.
PSI uses a shared personal-context bus to publish state and write-back affordances, turning isolated AI-generated modules into synchronized, chat-accessible instruments.
