A Benchmarking Framework for Context-aware XR Interfaces

Read the original on arXiv AI →

The paper introduces ContextXR, a benchmarking framework designed to evaluate context‑aware interfaces in Extended Reality (XR) systems. It models an XR application as a graph of functional facets—semantically coherent groups of capabilities that support a shared user intent—and uses this representation to build MineXR++, a dataset enriched with facet‑level annotations. The framework defines three core tasks—context factor analysis, initial facet suggestion, and next facet suggestion—and evaluates suggestion methods via a simulated interaction metric that measures navigation and search cost to reach desired functionality.

Generative Spatiotemporal Intent Sequence Recommendation via Implicit Reasoning in Amap

The paper introduces GPlan, a generative framework for Generative Spatiotemporal Intent Sequence Recommendation (GSISR) that integrates large language model reasoning into lightweight models. It employs Progressive Implicit CoT Distillation to compress reasoning into latent tokens for low-latency inference, and Spatiotemporal Counterfactual DPO to align plans with real-world constraints, improving sequence coherence and context responsiveness. Experiments and online A/B tests confirm the effectiveness of these techniques, and the authors provide an implementation and dataset on GitHub.
