The actuators control an extruder and a build-plate mounted on a fused deposition modeling (FDM) 3D printer, moving them horizontally or vertically. Our technique enables actuation of 3D-printed objects on the build-plate by controlling the actuators, and people can interact with them by connecting interface devices to the 3D printer. In this work, we describe how to actuate printed objects using the actuators and present several objects illustrated by our technique.","PeriodicalId":421706,"journal":{"name":"The 31st Annual ACM Symposium on User Interface Software and Technology Adjunct Proceedings","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121627741","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}

SurfaceStreams clients support on-the-fly background removal and rectification on a range of different capture devices (Kinect & RealSense depth cameras, SUR40 sensor, plain webcam). After preprocessing, the raw data is compressed and sent to the SurfaceStreams server, which can dynamically receive streams from multiple clients, overlay them using the removed background as mask, and deliver the merged result back to the clients for display. We discuss an exemplary usage scenario (3-way shared interactive tabletop surface) and present results from a preliminary performance evaluation.","PeriodicalId":421706,"journal":{"name":"The 31st Annual ACM Symposium on User Interface Software and Technology Adjunct Proceedings","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121470635","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}

Our overall research goal is to re-imagine what our bodies can do with the aid of wearable robotics using a body-remapping approach. To this end, we present an initial exploratory case study. MetaArms' two robotic arms are controlled by the user's feet motion, and the robotic hands can grip objects according to the user's toes bending. Haptic feedback is also presented on the user's feet that correlate with the touched objects on the robotic hands, creating a closed-loop system. We present formal and informal evaluations of the system, the former using a 2D pointing task according to Fitts' Law. The overall throughput for 12 users of the system is reported as 1.01 bits/s (std 0.39). We also present informal feedback from over 230 users. We find that MetaArms demonstrate the feasibility of body-remapping approach in designing robotic limbs that may help us re-imagine what the human body could do.","PeriodicalId":421706,"journal":{"name":"The 31st Annual ACM Symposium on User Interface Software and Technology Adjunct Proceedings","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122751694","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}
