我做脑机接口产品经理：碰到的3个难点

Core Insights - The article discusses the development and challenges of brain-computer interface (BCI) technology, particularly focusing on the integration with MR devices like Vision Pro [1][2]. Group 1: BCI Product Directions - There are three product directions for brain-computer interfaces: non-invasive, semi-invasive, and invasive [2]. - Non-invasive interfaces are expected to dominate the market in the coming years due to better cost and comfort, while invasive options are limited to medical patients [2][6]. Group 2: Market and Technology Challenges - The current market for BCIs is primarily focused on medical applications, with a significant gap in consumer electronics [6]. - The lack of a robust ecosystem for BCI technology in China hinders cost reduction and developer engagement [6]. Group 3: Data Collection and Processing - BCI product managers face challenges in data collection, testing, and annotation, similar to image recognition tasks [8]. - Existing datasets for brain signals, such as gestures and eye movements, facilitate development, but further data annotation is still required [8][9]. Group 4: Technological Breakthroughs - Recent research has achieved a 30% accuracy in reconstructing visual memories from non-invasive BCI signals, marking a significant advancement [9][11]. - Future improvements in signal reconstruction could potentially enhance accuracy to 50% or more, enabling experiences akin to memory recall [13][15]. Group 5: User Experience and Interaction - Current BCI product managers often lack a focus on user experience, leading to subpar interface design and usability [16][20]. - The interaction model for BCIs is still underdeveloped, with many systems lacking community engagement and user-friendly features [20][21]. Group 6: Future Directions - The future of BCI interaction is believed to lie in spatial computing, which could streamline data collection and interpretation without the need for secondary processing on flat devices [21].
