Abstract

Background: Sensory substitution and augmentation systems (SSASy) seek to either replace or enhance existing sensory skills by providing a new route to access information about the world. Tests of such systems have largely been limited to untimed, unisensory tasks.

Objective: To test the use of a SSASy for rapid, ballistic motor actions in a multisensory environment.

Methods: Participants played a stripped-down version of air hockey in virtual reality with motion controls (Oculus Touch). They were trained to use a simple SASSy (novel audio cue) for the puck's location. They were tested on ability to strike an oncoming puck with the SASSy, degraded vision, or both.

Results: Participants coordinated vision and the SSASy to strike the target with their hand more consistently than with the best single cue alone, t(13) = 9.16, p <.001, Cohen's d = 2.448.

Conclusions: People can adapt flexibly to using a SSASy in tasks that require tightly timed, precise, and rapid body movements. SSASys can augment and coordinate with existing sensorimotor skills rather than being limited to replacement use cases - in particular, there is potential scope for treating moderate vision loss. These findings point to the potential for augmenting human abilities, not only for static perceptual judgments, but in rapid and demanding perceptual-motor tasks.

多感官环境下快速运动任务的感官增强。

背景：感官替代和增强系统（SSASy）旨在通过提供获取世界信息的新途径，替代或增强现有的感官技能。对此类系统的测试大多局限于无时间限制的单感官任务：目的：测试在多感官环境中使用 SSASy 进行快速弹道运动的情况：方法：参与者在虚拟现实中使用体感控制装置（Oculus Touch）玩简化版空气曲棍球。训练他们使用简单的 SASSy（新颖的音频提示）来确定冰球的位置。他们接受了使用 SASSy、退化视觉或两者打击迎面而来的冰球的能力测试：结果：与单独使用最佳单一提示相比，受试者协调视觉和 SASSy 用手击打目标的一致性更高，t(13) = 9.16，p 结论：人们可以灵活地适应使用视觉和 SASSy：在需要严格计时、精确和快速肢体动作的任务中，人们可以灵活适应使用SSASy。SSASy可以增强和协调现有的感觉运动技能，而不是局限于替代性的使用情况，特别是在治疗中度视力损失方面具有潜在的空间。这些研究结果表明，不仅在静态感知判断方面，而且在快速和高要求的感知运动任务方面，SSASys 都具有增强人类能力的潜力。

期刊介绍： This interdisciplinary journal publishes papers relating to the plasticity and response of the nervous system to accidental or experimental injuries and their interventions, transplantation, neurodegenerative disorders and experimental strategies to improve regeneration or functional recovery and rehabilitation. Experimental and clinical research papers adopting fresh conceptual approaches are encouraged. The overriding criteria for publication are novelty, significant experimental or clinical relevance and interest to a multidisciplinary audience. Experiments on un-anesthetized animals should conform with the standards for the use of laboratory animals as established by the Institute of Laboratory Animal Resources, US National Academy of Sciences. Experiments in which paralytic agents are used must be justified. Patient identity should be concealed. All manuscripts are sent out for blind peer review to editorial board members or outside reviewers. Restorative Neurology and Neuroscience is a member of Neuroscience Peer Review Consortium.
