Similarity analysis of motion based on motion capture technology

This research has been successfully developed similarity analysis system of the human body motion from two kind of motions, the martial art actor motions comparing with reference motion capture data. This system used optical motion capture technology with 8 cameras. The system was able to show the calculation result of angle and angular velocity from every joints of human body motion. This system was able to performed 3D visualization of actor models and skeleton of reference data motion. The evaluation of the similarity motion was done by calculating the joint angle and angular velocity of the motions which is showed from the graphics of every joint with cosine similarity methods. The actor motion analysis in this research showed that average similarity level of joint angle has similarity value 0.816 and average angular velocity similarity 0.758.

Automatic plant watering controller component using FPGA device

Many farmers do not have much time to perform maintenance on agricultural plants, especially in watering of plant routinely. Besides that, sometimes watering was done not compatible with the water necessity of plants. This has an impact on agricultural products which is not maximized. In general, automatic plant watering used only watering timer-based, of course, is not in accordance with the characteristics of the water necessity of each plant. However, the automatic watering plants using soil moisture sensors can overcome problems of farmers. The prototype of automatic watering plant consists of FPGA board, driver relay, water pump, LED, soil moisture sensors, and the ADC module (ADC0820). Soil moisture sensor is a probe made from metal as soil moisture detector. Soil moisture measurement results in the form of voltage fluctuations. Soil moisture sensors generate a voltage that will be converted by the ADC module into 8-bit digital signal. The conversion results carried classification. This classification is based on ideal condition of the plant such as high water necessity, medium water necessity and low water necessity. If the sensor detects the soil in dry condition, the water pump will be activated. If the sensor detects the soil in wet conditions, the water pump will not be activated. Besides more easily, it also adjusts to the natural conditions and the needs of each plant. This research result is a description of component (IP Core) for controlling the watering system automatically.

Virtual Reality Website of Indonesia National Monument and Its Environment

National Monument (Monumen Nasional) is an Indonesia National Monument building where located in Jakarta. This monument is a symbol of Jakarta and it is a pride monument of the people in Jakarta and Indonesia country. This National Monument also has a museum about the history of the Indonesian country. To provide information to the general public, in this research we created and developed models of 3D graphics from the National Monument and the surrounding environment. Virtual Reality technology was used to display the visualization of the National Monument and the surrounding environment in 3D graphics form. Latest programming technology makes it possible to display 3D objects via the internet browser. This research used Unity3D and WebGL to make virtual reality models that can be implemented and showed on a Website. The result from this research is the development of 3-dimensional Website of the National Monument and its objects surrounding the environment that can be displayed through the Web browser. The virtual reality of whole objects was divided into a number of scenes, so that it can be displayed in real time visualization.

Automatic controller component development using FPGA device

This article present the design of automatic component to control room condition. The lights and fan will turn on in accordance ideal temperature workspace when there are peoples in the room and if no one in the room then the room lights and fan will not be active. This research use PIR sensor and LM35 as input, a component is developed based on FPGA device. The IP core of component is ready to fabricate, this design uses only 1 slice portion of the FPGA. Automation is one of the important things to support ease of human life; an automatic device also provides comfort in the activities so the people do not need to do it manually. Besides the easiness, it is also a positive impact on users such as energy savings, because everything is done by machines programmed in accordance with the level of accuracy.
