Nowadays Eye tracking technology is the next challenges of human computer interaction (HCI). This technology can help people all over the worldaccess computers through systems that use gaze control and especially important for people with physical disability. This research presents a system of assistive technology base on an eye-tracking interface while supported the communication system for independent living of persons with disabilities usability. The primary method of this system consists of a selection of pictogram buttons on three websites which used a low-cost eye-tracking device. The evaluation used the throughput of standards for computer pointing devices as a measurement of user performance to look at an on-screen target and dwell on it for 500ms for selection. The results showed that ten participants with a disability can be pointing and selection their overall mean throughput was 1.08 bits/s. Moreover the overall users of respondents were rather satisfied with the system. Consequently eye tracking technology is a great tool for interaction in the web application for a user with a disability.

The research project investigated the effects of CoO additive on dielectric ferroelectric physical and mechanical properties of modified Bi0.5(Na0.81K0.19)0.5TiO3 ceramics were investigated. The samples were synthesized by solid state reaction technique where powders were calcined at 850 °C for 4 h and ceramics were sintered at 1050 °C for 4 h which difference heating rate controlled i.e. 100 300 and 600 °C/h for. The ceramics of BNKT/x wt.% CoO was added CoO by various x=0.00 0.10 0.20 0.30 0.60 and 0.90. Phase formation was determined by X-ray diffraction technique (XRD). The X-ray diffraction analysis of the ceramics suggests that all samples exhibited a perovskite structure. The dielectric properties under room temperature and various temperatures were also determined. Dielectric measurement data showed that the additive and heating rate controlled influenced dielectric constant and dielectric loss. Furthermore the hysteresis loop behaviors slightly changed with increasing the CoO contents.

The establishment of Information Systems to promote the Community Enterprise ion of Ban Tham Sua Village Kaeng Krachan District Phetchaburi was aimed to build effective information management system to facilitate its management to be more convenient fast and up-to-date in order to increase wider distribution channels and disseminate the activities. Also it was aimed to evaluate the satisfaction with the information community using PHP5 HTML5 CSS3 phpMyAdmin in database design and photo retouching software as a tool for the system development. The questionnaire was used to evaluate the satisfaction of the system and website. The samples used in the experiment lived in Ban Tham Sua Moo 3 Kaeng Krachan District Phetchaburi Province. The constructed system made the operation more convenient. The data were collected and classified by the product type. The research found that the information system to promote Ban Tham Sua community business in Kaeng Krachan District Phetchaburi was constructed with an average efficiency of 4.60 considered as the highest level helping to manage the community enterprise information to enhance product distribution channels and to disseminate the community enterprise activities. The results of the satisfaction assessment on the Information System for Promoting the Enterprise of Ban Tham Sua collected from 30 people was 4.57 the highest level showing that the information system to promote the community enterprise of Ban Tham Sua Kaeng Krachan Phetchaburi can be applied for the future use.

The objective of this research was to determine and estimate the quality of ground water for producing village-tap water without pre-treatment in 3 districts Samchuk Nongyasai and Dermbangnangbuat districts Suphanburi province. Villagetap water was collected from 88 boreholes covered 17 sub-districts in June 2014 and January 2015 using standard method and then correctly preserved before analysis process. The result showed that pH conducted in filed using pH meter found in the range 7.0 to 9.2. Total hardness was found in the range of 110 to 590 mg/L as CaCO3. The concentration of Mn Fe Pb was found in the range of 0.08 - 0.88 mg/L nd - 1.88 mg/L and nd - 0.07 mg/L respectively. The concentration of Cd was to be non-detectable for all samples. The result found that total hardness was found higher value than standard quality water according to publish by Ministry of Natural Resources and Environment Thailand. The contamination of Mn and Fe in some samples was higher value than maximum allowable concentration. The problem of Fecontamination can extremely affect to physical properties of quality water. The production of household-water filtration in this work was modified from Bureau of Community Technology Department of Science Service Ministry of Science and Technology. The technology communication of the production household-water filtration was conducted by workshop procedure. The production household-water filtration was conducted step-by-step. All participants can produce the household-water filtration by themselves.

This research presents a bamboo chopsticks machine with automatic control system. The production of bamboo chopsticks the current will be cut to get the machine to enter the bamboo chopsticks using the machine. The machine will hammer bamboo rotation of the electric motor. The AC motors with high power. Currently the production of chopsticks mostly small businesses. Lower costs which resulted in lack of effective security. This research presents the design and techniques with bamboo chopsticks production automation. The objective is to make the production of bamboo chopsticks are secure and compliant. To increase productivity and reduce the danger of the machine. In designing the Arduino technology is used in the development of electronic prototypes designed to be user for both hardware and software advanced application control equipment used in the production of chopsticks for safe to use on the incidence of danger from the use.
