“…We will also consider the possibility to reuse the results of other researches about the relation between body type and BSIPs and further conclude the relation between body type and CoM calculation. Some novel technology will also be used to improve this research, e.g., Sensors [44], Virtual Rehabilitation [28] [22], Optimization Algorithm [11].…”

This is the preprint version of our paper on REHAB2015. A balance measurement software based on Kinect2 sensor is evaluated by comparing to Wii balance board in numerical analysis level, and further improved according to the consideration of BFP (Body fat percentage) values of the user. Several person with different body types are involved into the test. The algorithm is improved by comparing the body type of the user to the 'goldenstandard' body type. The evaluation results of the optimized algorithm preliminarily prove the reliability of the software.

“…Virtual reality has been widely applied in many fields range from everyday entertainment and communication [12] [34] to traditional research fields such as geography [21] [29], ocean [27] [19], city [18] [9] [8] and biology [30] [20], clinical assist [13] [14] [17]. Some novel interaction approaches are considered to be integrated in our future work [11] [16] [15].…”

“…No zero value pitches estimated also reveals that Autocorrelator and Fft The flaws of Autocorrelator and Fft are that the pitch estimation errors happen when the midi note numbers are more than 60, which means the two algorithms are not suitable for high-pitched voice. Fortunately, the limit of patient voice pitch is 60 as we mentioned in our previous work [13], so the limit of the two algorithms are in the scope of the patients' voice. Therefore, Autocorrelator is the most suitable candidate algorithm for patient voice pitch estimation.…”

“…As we have mentioned, in our previous work [13] the frequency of the patient voice is identified by FFT (Fast Fourier Transform) based frequency-domain approach which turns the voice wave into a frequency distribution. Further more, the pitch (tone) and midi number are calculated depend on frequency.…”

“…We define our research as a biometric information management system design, in which the biometric refer to voice pitch specifically, while serious games are employed as the user interface. In our previous research [13], we mentioned that our design science based software development just go forward a step, and thus 'the next step is to iteratively improve it and to develop experiments to test it before eventually moving on to conducting clinical tests as the assistive tool for rehabilitation of dysphonic patients'. Therefore, we recorded and assessed the feedback from the treatments for improving the assistive tool.…”

An assistive training tool software for rehabilitation of dysphonic patients is evaluated according to the practical clinical feedback from the treatments. One stroke sufferer and one parkinson sufferer have provided earnest suggestions for the improvement of our tool software. The assistive tool employs a serious game as the attractive logic part, and running on the tablet with normal microphone as input device. Seven pitch estimation algorithms have been evaluated and compared with selected patients voice database. A series of benchmarks have been generated during the evaluation process for technology selection.

This is the preprint version of our paper on ICONIP. Outdoor augmented reality geographic information system (ARGIS) is the hot application of augmented reality over recent years. This paper concludes the key solutions of ARGIS, designs the mobile augmented reality pipeline prospect system (ARPPS), and respectively realizes the machine vision based pipeline prospect system (MVBPPS) and the sensor based pipeline prospect system (SBPPS). With the MVBPPS's realization, this paper studies the neural network based 3D features matching method. IntroductionSince the human activities are related with the geographic information all the time, it is very natural and extremely important to integrate the augmented reality technology with the GIS. Since its generation, the augmented reality has gone through several development phases: computer indoor augmented reality, helmet-type outdoor augmented reality and mobile based outdoor augmented reality. Its application is gradually converted from the traditional exhibition to the application combined with the industry. This paper studies the mobile based outdoor augmented reality geographic information system (ARGIS) [1-3] and analyzes it by combining the examples for underground pipeline prospect. In the process of the realization of the examples, this paper also studies the neural network based 3D features matching method to optimize the feature matching process.The traditional GIS application is displayed on the map in the form of 2D symbols after analyzing the result based on the 2D maps. However, due to the lack of strong intuition, it is difficult for the user with weak geographic knowledge to distinguish it; even the field experts also have some difficulties in distinguishing in a complicated environment. For recent years, with the 3DGIS and VRGIS development, the 3D virtual model of real environment was established to replace the 2D map [4], which improves the intuition of marker distinguishing and promotes the visualization development of GIS. However, the 3D virtual model has high requirements on hardware while it still has difference with the real world scene.As a matter of fact, the real world scene is a complicated and perfect "3D space map" for itself. If the real world scene is taken as the "map" for GIS application operation and the inquired and analyzed result is displayed on the real world scene via virtual information to achieve the interaction between the virtual space geographic information and the real world scene, so the GIS application experience can be enhanced.Carry out scene augmentation [5,6] for human's visual system by organically integrating the 2D or 3D pictures, text notes and other virtual information generated by the computer into the real world scene which can be seen by the user. The augmented reality has the effect of expressing the sense of reality but Operational resultsOperating environment of application is nexus 5 mobile, and operating system is android 4.4/5.0.1.Data server: i5-3470 CPU, 16G memory, window server 2013.MVBPPS is subjected...
