Project 1_ concept II

PROJECT ONE

Digitalizing Hand Signal

 

BACKGROUND

The gestures are a form of nonverbal communication in which visible bodily actions are used to communicate important message. It includes movement of the hands, face, or other parts of the body.

OBJECTIVE

To modify and understanding symbolic hand signals and a new approach to digital design formats.

CONCEPT

The hand signal is nonverbal communication. Using the hand signal, we send important messages to other without any words. By looking at it, we can receive messages even so far away from the messenger. This hand signal brings questions into relationship between verbal communication and nonverbal communication.

If, Hand signal is converting to digital sound, how that could be modifying in digital media design?

 

METHOD

STEP ONE

Using the Kinect, determine the hand signal

STEP TWO

X,Y points à Frequency (Amplitude/Time)  

• Using the method of frequency. 
• Looking at the Hand signal pattern like as a frequency graph.

STEP THREE
VVVV
Import:  frequency graph (Hand signal pattern)
Output: convert to digital audio.

Analog & Digital

Tin can telephone

“A tin can telephone is a type of acoustic (non-electrical) speech-transmitting device made up of two tin cans, paper cups or similarly shaped items attached to either end of a taut string or wire. It is a form of mechanical telephony, where sound is converted into and then conveyed by vibrations along a liquid or solid medium, and then reconverted back to sound.” (wikipedia)

Concept:

Transmitting analog sound signal to digital signal language.

Analog sound through tin can > translate to > digital signal language
