We describe the development of a new ubiquitous music metaphor for creative action involving the use of hand gestures, Handy. The metaphor was deployed through two proof-of-concept, low-cost prototypes based either on motion sensors connected to an embedded micro-controller (Handy H) or by repurposing the webcam of a portable computer (Handy S). The evaluations showed positive results (slightly better with musicians than with non-musicians) in the following factors: ease of use and productivity (Handy H); engagement, productivity and collaboration support (Handy S). We discuss the implications of this outcome, targeting the interaction with the Internet of Musical Things.

方便的比喻：音乐物联网的双手、非接触式交互

我们描述了一种新的无处不在的音乐隐喻的发展，用于涉及使用手势的创造性动作，Handy。这个比喻是通过两个概念验证、低成本原型部署的，这些原型基于连接到嵌入式微控制器 (Handy H) 的运动传感器，或者通过重新利用便携式计算机的网络摄像头 (Handy S)。评估在以下因素中显示出积极的结果（音乐家比非音乐家略好）：易用性和生产力（Handy H）；参与、生产力和协作支持 (Handy S)。我们讨论了这一结果的影响，目标是与音乐物联网的互动。
