Tree climbing is one technique used for this. Climbers go to the top of the tree and use hand held equipment to collect and make notes while they are descending. This process demands expert climbing skills and biology expertise, which are two characteristics not commonly found. This paper describes the design of mobile system for 3D data collection and reconstruction of the field research environment for remote evaluation. The prototype can be used to reduce the time spent up trees and collected data that can be used for crowd-sourced evaluation.","PeriodicalId":243902,"journal":{"name":"SIGGRAPH Asia 2017 Mobile Graphics & Interactive Applications","volume":"442 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124605238","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}

In this paper, we present a mobile ray tracing system that aims to render large scenes with many millions of triangles at interactive speeds on a small-scale mobile cluster. To mitigate performance degradation due to excessive data communication on mobile and wireless networks with still high latency, we employ a tile-based rendering strategy where each participating mobile device keeps an entire copy of the necessary rendering data. To realize such a system, we compress the 3D scene data to a size loadable into graphics memory, which enables an effective mobile GPU ray tracing. Also, by using a careful interaction scheme between the master and slave devices in the mobile cluster, we enhance the efficiency of the mobile distributed GPU ray tracing markedly.","PeriodicalId":243902,"journal":{"name":"SIGGRAPH Asia 2017 Mobile Graphics & Interactive Applications","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126767487","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}

Thanks to their multi-modal acquisition capabilities and their growing processing power, they can perform increasingly sophisticated computer vision and data fusion tasks. In this context, we summarize our recent advances in the acquisition and reconstruction of indoor structures, describing the evolution of the methods from current single-view approaches to novel mobile multi-view methodologies. Starting from an overview on the features and capabilities of current hardware (ranging from commodity smartphones to recent 360° cameras), we present in details specific real-world cases which exploit modern devices to acquire structural, visual and metric information.","PeriodicalId":243902,"journal":{"name":"SIGGRAPH Asia 2017 Mobile Graphics & Interactive Applications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127589723","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}

The 3D physical topographic front of Duopography acts as a tangible interface, enabling sketching directly on the 3D terrain, as well as visual augmentation of the topography. At the same time, Duopography's flat back-of-device supports gestures that are hard to perform on the irregular front, allowing common interaction techniques such as panning and pinching. We contribute a prototype and the results of a preliminary evaluation of a dual-surface topography interface combining 3D printed front and a flat back-of-device.","PeriodicalId":243902,"journal":{"name":"SIGGRAPH Asia 2017 Mobile Graphics & Interactive Applications","volume":"308 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120930599","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}

By integrating the key-frames captured with external depth sensor as one single 3D point-cloud data set, our system could reconstruct the entire local physical workspace into the VR world. In this case, the remote helper could observe the local scene independently from the local user's current head and camera position, and provide gesture guiding information even before the local user staring at the target object. We conducted a pilot study to evaluate the usability of the system by comparing it with our previous oriented view system which only sharing the current camera view together with the real-time head orientation data. Our results indicate that this entire scene capturing and sharing system could significantly increase the remote helper's spatial awareness of the local work environment, especially in a large-scale workspace, and gain an overwhelming user preference (80%) than previous system.","PeriodicalId":243902,"journal":{"name":"SIGGRAPH Asia 2017 Mobile Graphics & Interactive Applications","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121575001","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}
