Kinetic Particles Synthesizer Using Multi-Touch Screen Interface of Mobile Devices
نویسندگان
چکیده
We developed a kinetic particles synthesizer for mobile devices having a multi-touch screen such as a tablet PC and a smart phone. This synthesizer generates music based on the kinetics of particles under a two-dimensional physics engine. The particles move in the screen to synthesize sounds according to their own physical properties, which are shape, size, mass, linear and angular velocity, friction, restitution, etc. If a particle collides with others, a percussive sound is generated. A player can play music by the simple operation of touching or dragging on the screen of the device. Using a three-axis acceleration sensor, a player can perform music by shuffling or tilting the device. Each particle sounds just a simple tone. However, a large amount of various particles play attractive music by aggregating their sounds. This concept has been inspired by natural sounds made from an assembly of simple components, for example, rustling leaves or falling rain. For a novice who has no experience of playing a musical instrument, it is easy to learn how to play instantly and enjoy performing music with intuitive operation. Our system is used for musical instruments for interactive music entertainment.

متن کاملMobiGaze : Gaze Interface for Mobile Devices
Today, touch-screen-based handheld mobile devices are widely used; however, they are awkward to use with one hand. We propose MobiGaze, which is a user interface that uses one’s gaze to operate a handheld mobile device. By using MobiGaze, one can target the entire display area easily, even when the device is quite large. Moreover, MobiGaze can use both gaze and touch interactions. The combinati...

Since 6000 years humans have used maps to navigate through space and solve other spatial tasks. Nearly all of time maps were drawn or printed on a piece of paper (or on material like stone or papyrus) of a certain size. Thus the two most common interaction methods were: (i) Holding the map in both hands (ii) or putting the map on a tabletop and perform specific tasks. Nowadays maps can be displ...
متن کاملUsing the Touch Screen as a Controller for Portable Computer Music Instruments
Using mobile devices as instruments in computer music is one of the goals of the “Pure Data anywhere” project [5]. An obstacle we encounter is controllability, because most of the devices do not offer the necessary interface, such as MIDI or USB, in order to be controlled by external controllers. Also, attaching external controllers to the devices would make them less portable. This paper inves...
