What technology does skinput use?
bio-acoustic sensing
Skinput is an input technology that uses bio-acoustic sensing to localize finger taps on the skin. When augmented with a pico-projector, the device can provide a direct manipulation, graphical user interface on the body.
Why Skinput technology?
In the skinput technology, our skin can be used as an input surface. Skinput technology allows the human skin for acoustic transmission so that we can give inputs and information through our skin, to control the smart phones or other mobile devices like iPods, MP3 players, smart phones etc.
What is bio acoustic sensing?
Bioacoustic Sensing combines sensing technology, machine learning, biology and acoustics. This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they disperse through. Listening is one of the main methods used in bioacoustical research.
What is psychoacoustics the study of?
Psychoacoustics is the scientific study of sound perception and audiology. This includes speech, music, and other sound frequencies that travel through our ears. Knowing the limits of human hearing is a good way to familiarize yourself with psychoacoustics.
How is sound used in biotechnology?
Application of ultrasound to biotechnology is relatively new, but several processes that take place in the presence of cells or enzymes are activated by ultrasonic waves. High intensity ultrasonic waves break the cells and denaturize the enzymes. Reverse micelles can be used to carry out synthesis using enzymes.
What is the meaning of psychoacoustics?
Definition of psychoacoustics : a branch of science dealing with the perception of sound, the sensations produced by sounds, and the problems of communication.
How do we produce sounds?
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
What is plant acoustic frequency technology?
Abstract: Plant Acoustic Frequency Technology (PAFT) is a tool with the method of using acoustic waves to stimulate the opening of stomata, the purpose is to intensify the absorption of nutrients needed by plants through the leaves.
What is forward and backward masking?
Forward masking refers to the masking of a tone by a sound that ends a short time (up to about 20 or 30 ms) before the tone begins. Backward masking refers to the masking of a tone by a sound that begins a few milliseconds after the tone has ended.
What is masking and its types?
Masking is the process by which the threshold of hearing for one sound is raised by the presence of another sound. Upward spread of masking is low-frequency sounds masking high-frequency sounds. Downward spread of masking occurs when low-frequency sounds are masked by an intense level of high-frequency sounds.
