Abstract: A Non-Contact Digital Music System has been conceptualized and implemented to create a new era of digital music. This system replaces the strings of a traditional stringed instrument with laser beams to avoid bruising of the user’s hand. The system consists of seven laser modules, detector modules and distance sensors that form the basic hardware blocks of this instrument. Arduino ATmega2560 microcontroller is used as the primary interface between the hardware and the software. MIDI (Musical Instrument Digital Interface) is used as the protocol to establish communication between the instrument and the virtual synthesizer software.
Abstract: The study aimed to identify the nature of autistic
talent, the manifestations of their weak central coherence, and their
sensory characteristics. The case study consisted of four talented
autistic males. Two of them in drawing, one in clay formation and
one in jigsaw puzzle. Tools of data collection were Group Embedded
Figures Test, Block Design Test, Sensory Profile Checklist Revised,
Interview forms and direct observation. Results indicated that talent
among autistics emerges in limited domain and being extraordinary
for each case. Also overlapping construction properties. Indeed, they
show three perceptual aspects of weak central coherence: The weak
in visual spatial-constructional coherence, the weak in perceptual
coherence and the weak in verbal – semantic coherence. Moreover,
the majority of the study cases used the three strategies of weak
central coherence (segmentation, obliqueness and rotation). As for
the sensory characteristics, all study cases have numbers of that
characteristics that especially emerges in the visual system.
