An Exploratory Study of Augmented Reality Presence for Tutoring Machine Tasks

by Yuanzhi Cao | Mar 1, 2020 | 2020, Convergence Accelerator, Featured Publications, Future of Work, Karthik Ramani, Ke Huo, Publications, Recent Publications, Tianyi Wang, Xun Qian, Yuanzhi Cao

Machine tasks in workshops or factories are often a compound sequence of local, spatial, and body-coordinated human-machine interactions. Prior works have shown the merits of video-based and augmented reality (AR) tutoring systems for local tasks. However, due to the...

Meta-AR-App: An Authoring Platform for Collaborative Augmented Reality in STEM Classrooms

by Ana Villanueva | Mar 1, 2020 | 2020, Ana Villanueva, Convergence Accelerator, Featured Publications, Future of Work, Karthik Ramani, Publications, Recent Publications, Zhengzhe Zhu, Ziyi Liu

Augmented Reality (AR) has become a valuable tool for education and training processes. Meanwhile, cloud-based technologies can foster collaboration and other interaction modalities to enhance learning. We combine the cloud capabilities with AR technologies to present...

Autonomous Robotic Exploration and Mapping of Smart Indoor Environments With UWB-IoT Devices

by Tianyi Wang | Feb 9, 2020 | 2020, Karthik Ramani, Ke Huo, Publications, Recent Publications, Tianyi Wang

The emerging simultaneous localization and mapping (SLAM) techniques enable robots with the spatial awareness of the physical world. However, such awareness remains at a geometric level. We propose an approach for quickly constructing a smart environment with semantic...

Using Social Interaction Traced Data and Context to Predict Collaboration Quality and Creative Fluency in Collaborative Design Learning Environments

by Convergence Design Lab Admin | Jan 28, 2020 | 2020, Karthik Ramani, Publications, Recent Publications

Engineering design typically occurs as a collaborative process situated in specific context such as computer-supported environments, however there is limited research examining the dynamics of design collaboration in specific contexts. In this study, drawing from...

Latent transformations neural network for object view synthesis

by Sangpil Kim | Nov 15, 2019 | 2019, Hyunggun Chi, Karthik Ramani, Publications, Recent Publications, Sangpil Kim

We propose a fully convolutional conditional generative neural network, the latent transformation neural network, capable of rigid and non-rigid object view synthesis using a lightweight architecture suited for real-time applications and embedded systems. In contrast...

GhostAR: A Time-space Editor for Embodied Authoring of Human-Robot Collaborative Task with Augmented Reality

by Yuanzhi Cao | Oct 14, 2019 | 2019, Featured Publications, Future of Work, Industrial Innovation and Partnerships, Information and Intelligent Systems, Karthik Ramani, Ke Huo, Pawan Rao, Publications, Recent Publications, Tianyi Wang, Xun Qian, Yuanzhi Cao

We present GhostAR, a time-space editor for authoring and acting Human-Robot-Collaborative (HRC) tasks in-situ. Our system adopts an embodied authoring approach in Augmented Reality (AR), for spatially editing the actions and programming the robots through...
