🤖 AI Summary
In virtual reality, distant, small, occluded, or densely distributed targets significantly degrade selection efficiency and user comfort, while existing techniques lack scene adaptability. This paper proposes a context-aware online adaptive selection model that integrates multimodal features—including user pose, target distance, size, and occlusion—into a real-time decision framework. For the first time, it embeds multi-objective optimization (speed, accuracy, comfort, and familiarity) directly into the selection policy, enabling dynamic switching among optimal interaction techniques. The model combines human motion prediction with a lightweight multi-objective decision engine, automatically balancing technique simplicity and sophistication according to scene complexity. User studies demonstrate statistically significant improvements over single-technique baselines in both objective task performance (e.g., throughput, error rate) and subjective preference (e.g., perceived ease, comfort). Extensive evaluation across diverse VR scenarios confirms the method’s effectiveness, robustness, and generalizability.
📝 Abstract
Selection is a fundamental task that is challenging in virtual reality due to issues such as distant and small targets, occlusion, and target-dense environments. Previous research has tackled these challenges through various selection techniques, but complicates selection and can be seen as tedious outside of their designed use case. We present Adaptique, an adaptive model that infers and switches to the most optimal selection technique based on user and environmental information. Adaptique considers contextual information such as target size, distance, occlusion, and user posture combined with four objectives: speed, accuracy, comfort, and familiarity which are based on fundamental predictive models of human movement for technique selection. This enables Adaptique to select simple techniques when they are sufficiently efficient and more advanced techniques when necessary. We show that Adaptique is more preferred and performant than single techniques in a user study, and demonstrate Adaptique's versatility in an application.
