Furthermore, touchscreen-based user interfaces are now commonly used in mobile computers such as smartphones and tablets. When we anticipate that future computers will become invisible, that is, computing functionality will be completely embedded into household appliances, furniture, and houses, our interactions will not be limited to things on a display or a tabletop. In such situations, pleasantness may become important as well as accuracy and efficiency in interface design. This study presents a new scheme for detecting 3D positions of objects in water, based on our experiences with the development of aquatic interactive systems. For the detection of objects on a certain 2D layer in water, a line laser is used with a camera. Stacking multiple line lasers enables the detection of object positions in a 3D space.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80620172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depending on the accuracy and the density of the points of data collection, this could be applied for different uses. Analyzing the time series data of the pressure, it is possible (1) to detect faults in walking and balancing problems for old people, (2) to design personalized foot orthoses, (3) to calculate the calorie burnt, even when walking and jogging are mixed, and the road slope changes, (4) to find subtle faults in sprinters or tennis players, (5) for person identification, (6) even for initiating alarm arising from mishandling of machines (like accelerator pedal of a car). In this work, we look for an efficient, real-time, yet cheap solution. We use a few thin, cheap, resistive pressure sensors, placed at critical points on the insole of the shoe to collect dynamic pressure data, preprocess it and extract features to identify the mobility speed. Nearly 100% classification accuracy was achieved. Thus, the target to classify whether the person is walking or jogging or climbing up or down the stairs was found to be possible, even with very simple gadget. From the time duration and the speed, the distance travel could be calculated. If, in addition, this signal could tell us the body-weight, we could accurately calculate the calorie burnt at the end of the day. The analysis method, and results from real experiments are discussed.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82672081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective gesture recognition is helpful to not only provide services for health monitoring, but also develop various applications like appliance control and emergency call. However, significantly individual difference of gesture performance brings challenge for accurate gesture recognition. In this paper, a personalized method of gesture recognition is proposed, which can analyze personal gesture features and automatically adjust gesture templates to improve recognition accuracy. The method was evaluated on a finger-worn device named Magic Ring that collected eight gestures from three subjects for one week testing. Results show the effectiveness of the method that average improvement of 16% in recognition accuracy has been achieved.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82940191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Much efforts have been focused on the development of dictionary learning algorithms so that the sparse representation of signals can be efficiently performed. In this paper, we propose a method for learning a signal dependent overcomplete dictionary. This is accomplished by posing the sparse representation of signals as a problem of matrix factorization with a sparsity constraint. By generalizing the conventional coordinate descent method, we develop a so-called sparse alternating parallel coordinate descent (SAPCD) algorithm, which is structured by iteratively solving the two optimal problems, the learning process of the dictionary and the estimating process of the coefficients for constructing the signals. Numerical experiments demonstrate that the proposed algorithm performs better than the famous K-SVD algorithm and several other algorithms for comparison.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89232766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Still commercial studios cannot have full interaction between actors and virtual scene because actors data are not completely digital available as well as the feedback for actors is still not sufficient. Markerless full body tracking might revolutionize virtual studio technology as it allows better interaction between real and virtual world. This article reports about using a markerless actor tracking in a virtual studio with a tracking volume of nearly 40 cubic meter enabling up to three actors within the green box. The tracking is used for resolving the occlusion between virtual objects and actors so that the Tenderer can output automatically a mask for virtual objects in the foreground in case the actor is behind. It is also used for triggering functions scripted within the Tenderer engine, which are attached to virtual objects, starting any kind of action (e.g., animation). Last but not least the system is used for controlling avatars within the virtual set. All tracking and rendering is done within a studio frame rate of 50 Hz with about 3 frames delay. The markerless actor tracking within virtual studios is evaluated by experts using an interview approach. The statistical evaluation is based on a questionnaire.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78904247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by the biological acoustic awareness of human hearing system and the visual saliency talent of human vision, a heterogeneous information saliency feature fusion (HISFF) approach which simulates human awareness of environment sound for machine's awareness is proposed in this paper. The sound signal is visualized by using the Short-Time Fourier Transform (STFT) algorithm in order to convert the acoustic saliency into visual saliency, and the Mel-Frequency Cepstrum Coefficient (MFCC) is used to represent the human acoustic awareness. The proposed HISFF approach is tested by using the environment sound data which collected from the real world of both indoor and outdoor environment. The results show that this approach is able to extract the saliency signal from both long-term and short-term sound signal successfully and clearly, and conducts to very distinguishable features for machine's environment sounds based awareness.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79231962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
