With the increasing efficiency of life-support systems and better intensive care, more patients survive severe injuries of the brain and spinal cord. Many of these patients experience locked-in syndrome: The active mind is locked in a paralyzed body. Consequently, communication is extremely restricted or impossible. A muscle-independent communication channel overcomes this problem and is realized through a brain-computer interface, a direct connection between brain and computer. The number of technically elaborated brain-computer interfaces is in contrast with the number of systems used in the daily life of locked-in patients. It is hypothesized that a profound knowledge and consideration of psychological principles are necessary to make brain-computer interfaces feasible for locked-in patients.
随着生命支持系统效率的提高和重症监护条件的改善，越来越多的患者在遭受严重脑损伤和脊髓损伤后得以存活。这些患者中有许多人患有闭锁综合征：活跃的思维被困在瘫痪的身体里。因此，交流受到极大限制甚至无法进行。一种不依赖肌肉的交流通道可以克服这个问题，它通过脑机接口来实现，即大脑与计算机的直接连接。技术上精心设计的脑机接口数量与闭锁综合征患者日常生活中使用的系统数量形成了反差。据推测，要使脑机接口对闭锁综合征患者可行，深入了解和考虑心理学原理是必要的。
