We selected 31 natural and interaction-oriented hand gestures that can be adopted for general-purpose control of and communication with computing systems. The data glove is custom-built, and contains 13 bend sensors, 7 motion sensors, 5 pressure sensors and a magnetometer. We present the data collection experiment, as well as the design, selection and evaluation of a classification algorithm. As we use a sliding window approach to data processing, our algorithm is suitable for stream data processing. Algorithm selection and feature engineering resulted in a combination of linear discriminant analysis and logistic regression with which we achieve an accuracy of over 98.5% on a continuous data stream scenario. When removing the computationally expensive FFT-based features, we still achieve an accuracy of 98.2%.","PeriodicalId":175060,"journal":{"name":"2016 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133667203","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}

However, the effect of small delay has not been investigated sufficiently. Therefore the purpose of this study was to reveal the effect of a small latency on the subjects. The subjects were asked to stand on the force plate with one foot so that the length of body sway can be measured with several lags ranging from 1 ms to 66 ms. The experiments showed that 1) the sway increased linearly as the latency got longer 2) the HMD with latency of 1 ms also degraded the sense of balance compared to the naked eye with the same limited field of view (FOV) as in HMD, and 3) the difference between the virtual and real worlds' content had an effect on the result of the experiment. From these results, user's stability can be regarded as the direct index of the quality of VR system for the user.","PeriodicalId":175060,"journal":{"name":"2016 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121681431","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}

A conceptual model presents the combination of vibrations from multiple elements (tactors) as a two-stage pairing of tactors into virtual tactors, considering the 2D dimensionality. To support irregular triangle meshes, we suggest parameters to characterize triangle shape and a future study to measure sensations for varying shape. Gathered data will be used to assess and compare perceptual combination models and to develop precise rendering functions for irregular triangle meshes.","PeriodicalId":175060,"journal":{"name":"2016 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115277218","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}

We introduce HMD-based augmented reality platform with smartwatch, and method to accurately calibrate orientation between smartwatch and HMD. We also implement natural 3D object manipulating system using 6-DOF hand tracker with hand grasping detection.

It maps inertial sensors, touch screen and physical buttons of a mobile phone into well-known gestures to alter the position, rotation and scale of virtual objects. As these transformations require the control of multiple degrees of freedom (DOFs), collaboration is proposed as a solution to coordinate the modification of each and all the available DOFs. Users are free to decide their own manipulation roles. All virtual elements are displayed in a single shared screen, which is handy to aggregate multiple users in the same physical space.","PeriodicalId":175060,"journal":{"name":"2016 IEEE Symposium on 3D User Interfaces (3DUI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128722364","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}
