personal mobile learning, a distance learning device using dvb technology
DESCRIPTION
APTECS 2nd ITS international conference Surabaya, Indonesia Aug '10 Personal Mobile Learning, a distance learning device. Designated to answer distance learning problem, start from teaching-learning problem, sometimes lecture in some condition, must absent in class, but the student need to earn the knowledge. Author indicated that time and place dimension sometime became barrier in educational world. So there’s opportunity in blue ocean area, to create a product which can be use to help teaching-learning process eventhough lecture and student in not in the same time & place. Thanks to fenomenal broadcast system innovation technology, DVB (Digital Video Broadcast), which can support personal broadcast methods to receive and transmit video, audio, image. User must only have a laptop and this set-up-box, no need a complete broadcast system product, so they can enjoy distance learning in their area. Personal Mobile Learning is a whole process in a product design. But the different is the methods, the starting point is not from the problem identification, but from the innovative technology finding then try to find idea in product apllication. Beside the design & technology, ergonomy and aesthetic still the main design consideration of this product. The image design are taken from keywords “simple-futuristic” style. The design process include sketch-rendering-modelling-prototypingTRANSCRIPT

Activity
There’s no television broadcasting technology-basedon digital technology
Tcchnology
Existing streaming video is quite time consuming OperationalRequires a t ool that combines the ability ofTelevision and Personal Computer
Technology
Indonesian society prevailing socio culturechallenge. Two prominent conditions, namely thaturban communities tend to be mobile, and sub-urbancommunities who still adhere to conventionalcustoms.
Socioculture
Existing Tele-learning methods, from the complexityof equipment needed, limiting the mobility of people.
Activity
Teachers with students meetings which are notpractical (must be met in the same place and time)
Ergonomy
Not open edutainment, teaching and learning processcan only be enjoyed by participants

Design Concept
Design Spesification Digital TV decoder with ability to transmit video, audio, still picture. Which also can receive Digital TV services Product design interface with a laptop as the main products that are complementary functions, because both products are used together There are 3 components in this product : DVB-RCT card, camcoder, speakerphone. Those 3 components have an PCMCIA’s output interface, which compatible with laptop
Design positionBased on technology content and practicability usage
design constraints
• Level of accuracy, these are small dimension and lightweight products, so the design and manufacturing accuracy of measurement process is important, with a tolerance limit of 0.01 mm
• DVB-RCT technology is still in research, yet at the launch and market in general. So that the community of potential users would have fingered the function, technology, operations of this product. It may even take penetration to the public awareness
• Prediction of future products is fully with high-tech content product, takes a detail measure of product-technology trends
