Dance has been made mandatory as one of the physical education courses in Japan because it can cultivate capacities for expression and communication. Among several types of dance education, creative dance especially contributes to the cultivation of these capacities. However, creative dance requires some level of particular skills, as well as creativity, and it is difficult to presuppose these pre-requisites in beginner-level dancers without experience. We propose a novel supporting device for dance beginners to encourage creative dance performance by continuously generating musical sounds in real-time in accordance with their bodily movements. It has embedded sensors developed for this purpose. Experiments to evaluate the effectiveness of the device were conducted with ten beginner-level dancers. Using the proposed device, the subjects demonstrated enhanced creative dance movements with greater variety, evaluated in terms of Laban dance movement description. Also, using the device, they performed with better accuracy and repeatability in a task where they produced an imagined circular trajectory by hand. The proposed interface is effective in terms of creative dance activity and accuracy of motion generation for beginner-level dancers.
日本将舞蹈列为一门体育必修课，因为它可以培养表达和交流能力。在几种类型的舞蹈教育中，创意舞蹈尤其有助于培养这些能力。然而，创意舞蹈需要一定水平的特殊技能和创造力，而对于没有经验的初学者来说，很难预先假定他们具备这些前提条件。我们提出了一种新颖的支持设备，用于鼓励舞蹈初学者通过根据身体动作实时不断生成音乐声音来进行创意舞蹈表演。它嵌入了为此目的开发的传感器。我们对 10 名初学者进行了评估该设备有效性的实验。使用所提出的设备，受试者展示了更具创意的舞蹈动作，这些动作的多样性通过拉班舞蹈动作描述进行了评估。此外，在一项通过手动产生想象中的圆形轨迹的任务中，他们使用该设备实现了更高的准确性和可重复性。对于初学者来说，该界面在创意舞蹈活动和运动生成的准确性方面都是有效的。
