Game Changers: Designing and Measuring Dynamic Feedback To Help Users Self-Regulate in a VR Pointing Game

The way games dynamically convey information through feedback is critical to players' ability to perform, learn, and improve. However, it is poorly understood how performance metrics impact player performance and perception in core game tasks like pointing or steering. With a virtual reality pointing task we systematically explored how three performance metrics driving the feedback affected players when rewarding short completion times, straight movements, or high peak speed. across different points in time - continuously, at end-of-action, or at end-of-task. On average the dynamic feedback helped people point more straight and faster, while for others it had small or opposite effect. The study quantitatively compared dynamic feedback across three forms with the metrics driving the form as the intended locus of quantitative comparison. Our work improves game designers basis for crafting dynamic feedback by helping them know when to employ feedback schemes that align with desirable game performance objectives.

What Holds Back Brain-Computer Interfaces? Uncovering Challenges and Opportunities in BCI-controlled Games for Cerebral Palsy Rehabilitation

Brain-computer interfaces (BCIs) offer promising avenues for cerebral palsy (CP) rehabilitation at home and in the clinic, using games that promote engagement and sustained training effort. Nonetheless, the design constraints of BCI-based CP rehabilitation remain unclear, especially how individuals with CP experience a sense of control through BCI, and how they experience computer-mediated game assistance. To address this gap, we present preliminary clinical and user perspectives on BCI-based CP rehabilitation, drawing on in-clinic insights from a CP therapist and experiential accounts from ten individuals with CP engaging with BCI game prototypes. Sporadic help in BCI games eased monotony, but also fostered doubts regarding agency. The therapist saw BCI rehabilitation as complementary to traditional training, facilitating the transition from playful exercises to autonomous, self-managed training. We outline key challenges and opportunities to inform and empower further design and research of BCI training for CP.
