Proceedings of the International Conference on New Interfaces for Musical Expression

• Year: 2013
• Location: Daejeon, Republic of Korea
• Pages: input interfaces, touch screens, tablets, pressure-sensitive, low-cost
• Keywords: 10 in materials, about1/10th the cost of existing solutions. The stylus makes use of the built inaudio interface that is available on most smartphones and tablets on the markettoday. Limitations of the device include the physical constraint of wires, theoccupation of one audio input and output channel, and increased latency equalto the period of at least one audio buffer duration. The stylus has beendemonstrated in two cases thus far: a visual musical score drawing and asinging synthesis application.
