Based on the idea of ES template (EST), an object-oriented rule-type EST is emphatically studied on such aspects as the object-oriented knowledge representation, the heuristic inference engine with an improved depth-first search (DFS) and the graphical user interface. A diagnositic ES instance for debris on magnetic chip detectors (MCDs) is then created with the EST. The spot running shows that the rule-type EST enhances the abilities of knowledge representation and heuristic inference, and breaks a new way for the rapid construction and implementation of ES.展开更多

Here, a system was established to record local field potentials (LFP) and extracellular signal or multiple-unit discharge and behavior synchronously by utilizing electrophysiology and integrated circuit technique. It comprised microelectrodes and micro-driver assembly, analog front end (AFE),while a computer (Pentium III ) was used as the platform for the graphic user interface, which was developed using the LabVIEW programming language. It was designed as a part of ongoing research to develop a portable wireless neural signal recording system. We believe that this information will be useful for the research of brain-computer interface.展开更多

The interface is able to control and command action with only hand. Four finger motions （left click, right dick, hold, drag） are used to command the interface. Also the authors materialiae cursor movement control using image processing The measure what they use for inference is entropy of Electromyogram （EMG） signal, Gaussian modeling and likelihood estimation. In image processing for cursor control, they use color recognition to get the center point of finger tip from marker, and map the point onto cursor. Accuracy of finger movement inference is over 95% and cursor control works naturally without delay. They materlalize whole system to check its performance and utility.展开更多

The SSC game’s target is to detect the player’s reacting capability, which is related closely with dementia. Our system reaches this target with some advantages: there are no temporal and spatial constraints at all. There is no cost, and it can even improve people’s mental status. Hand talk technology and EHMM gesture recognition approach are employed to realize the human computer interface. Experiments showed that this system can evaluate people’s reacting capability effectively and is helpful for initial dementia examination.展开更多

This study aimed at investigating the effects of nervous growth factor （NGF） on delayed afterdepolarizations （DADs） and triggered activity （TA） of the noninfarcted myocardium in the myocardial infarcted rabbit model. Rabbits with the left anterior descending coronary artery occlusion were prepared and recovered for 8 weeks （HMI group, n=9）. Other rabbits with myocardial infarction were infused NGF to the left stellate ganglion （HMI＋NGF group, 400 U/day for 8 weeks, n=8）. Myocytes were isolated from regions of the noninfarcted left ventricular free wall. Action potentials and ion currents were recorded with whole-cell patch clamp. The results showed that more DADs and TA events of HMI＋NGF myocytes than that of HMI and Ctrl group. Iti and ICa-L of NGF＋HMI myocytes were increased significantly compared with HMI and Ctrl cells, which contributed to DADs-related triggered arrhythmia. Comparing with HM1 and Ctrl myocytes, significant prolongations of APD50 and APD90 in HMI＋NGF myocytes were found. The results indicated the electrophysiological change of HMI myocytes with NGF infusion. It suggested that more events of DADs and TA in HMI myocytes with NGF treatment. The underlying mechanism may be involved in the increase of Iti and ICa-L.展开更多

Scandinavian design, with simple but not easy product appearance and shape, perfect man-machine interface, and very humane exotic customs, has led the global design industry trend, touching consumers＇ hearts all over the world since several decades of years ago. Dematerialization factors bound in Nordic-design are the root cause of the classic achievements. Dematerialization fully contains human touch, human factors. This is focusing on people-oriented design concepts, reflecting the best harmonious development of the modern world＇s ideas and themes. This article mainly takes Scandinavian-product design as an example-furniture and industrial design, and makes further exploration and research of dematerialization factors contained by products.展开更多

As technology developed, this tool gradually fell out of use in Taiwan. Yet for the older generation, the tool remains a symbol of the belief that hard work will lead to prosperity. This paper aimed to invoke these memories and beliefs through the design of an innovative museum exhibit. To achieve this, we designed a human-computer interface using the form and feel of this important historical artefact. We analyzed the design of this exhibit using the Idea-People-Object-Physical Attract-Engage-Flip （IPOP-AEF） model developed by Pekarik, Schreiber, Hanemann, Richmond, and Mogel （2014）. The designed exhibit ＂Hao Shi Duo Mo＂ was on show in Taiwan in May 2015. It was well-received by visitors, which was likely due to its fulfilment of each of the six elements of the IPOP-AEF model. This analysis serves as valuable reference for exhibition designer and artists.展开更多

Based on force control, a robotic subsystem has been developed for path automatic generation or path learning. Using a dummy tool and roughly taught guiding points around a part contour, the robot moves in position and force controlled hybrid mode, following the order of the guiding points and with contact force direction and value predefined. During the motion, robot actual position is recorded by the robot controller. After the motion, the recorded position data is used to generate a robot path program automatically. Robot lead-through may be used in the guiding point teaching. Furthermore, a GUI （graphical user interface） is developed on the teach pedant to guide through the guiding point creation and teaching, path learning, program verification and execution. The development has been incorporated into a robotic machining product option. Combination of the robot path learning function and GUI enhances the interaction between the robot and operator and drastically increases the level of robotic ease-of-use.展开更多

This paper tried to give universal criteria of HCI design for CAS systems through introduction of demonstration application, which is total knee replacement （TKR） with a nonimage-based navigation system. A typical computer assisted process can be divided into four phases： the preoperative planning phase, the intraoperative registration phase, the intraoperative navigation phase and finally the postoperative assessment phase. The interface design for four steps is described respectively in the demonstration application. These criteria this paper summarized can be useful to software developers to achieve reliable and effective interfaces for new CAS systems more easily.展开更多

文摘This paper describes an automated path generation method for industrial robots. Based on force control, a robotic subsystem has been developed for path automatic generation or path learning. Using a dummy tool and roughly taught guiding points around a part contour, the robot moves in position and force controlled hybrid mode, following the order of the guiding points and with contact force direction and value predefined. During the motion, robot actual position is recorded by the robot controller. After the motion, the recorded position data is used to generate a robot path program automatically. Robot lead-through may be used in the guiding point teaching. Furthermore, a GUI （graphical user interface） is developed on the teach pedant to guide through the guiding point creation and teaching, path learning, program verification and execution. The development has been incorporated into a robotic machining product option.
