摘要： The VideoHarp is an optical-scanning device for sensing and tracking the movement of multiple fingers which is then used to control the generation of light or sound or to control the motion of other physical objects. Preferably, the VideoHarp detects the images of a performer's fingertips using a single sensor. From these images, the movement of each fingertip is tracked and this information is translated into a standard output, which is preferably used to control a device which generates sound or light. The translation of the finger motion into control signals is programmable, enabling the VideoHarp to be played using a variety of different types of motions and gestures. For example, the VideoHarp may be played with harp-like or keyboard like gestures, by bowing or drumming motions, or even by gestures and motions with no analogue in existing instrument techniques.
摘要翻译： VideoHarp是用于感测和跟踪多个手指的运动的光学扫描装置，然后用于控制光或声音的产生或者控制其他物理对象的运动。优选地，VideoHarp使用单个传感器来检测表演者的指尖的图像。从这些图像中，跟踪每个指尖的运动，并将该信息转换成标准输出，其优选地用于控制产生声音或光的装置。手指运动转换为控制信号是可编程的，可以使用各种不同类型的运动和手势来播放VideoHarp。例如，VideoHarp可以像竖琴般的键盘一样，通过鞠躬或打鼓动作，甚至通过现有的仪器技术中没有模拟的手势和运动来播放。

摘要： A keyboard arrangement in electronic musical instrument comprising playing keys movable to cover a predetermined distance in normal play and also being able to move farther in excess of said distance in accordance with the pressure applied to the keys, a movable arm arranged at position corresponding to each key at its depressed position, and a sensor means provided for said arm to detect the amount of the excessive distance covered by the movable arm and the speed thereof to generate a signal to be used for the control of expression such as tone volume, tone color and the like.The keyboard arrangement preferably further includes a deformable cushion means normally nondeformingly contacting, at its upper end, the bottom surface of the movable arm member during the normal movement of the positionally corresponding key but is deformed when the key makes a movement in excess of the normal distance to be covered by the key. Thus, the arm is inhibited to develop undesirable vibrations during its movements and precise detection of the amount of its movement can be made.

摘要： In an electronic musical instrument, an expression control circuit constituted by a first variable resistor is connected in the path of the tone signal. A second variable resistor is connected in series with or in parallel to the first. A third variable resistor is connected in shunt between the output side of the expression control circuit and the ground. The second and the third variable resistors can adjust the variation range of the tone signal at the output of the first variable resistance.
