This paper introduces a collaborative learning game called Futura: The Sustainable Futures Game, which is implemented on a custom multi-touch digital tabletop platform. The goal of the game is to work with other players to support a growing population as time passes while minimizing negative impact on the environment. The design-oriented research goal of(More)
With the Web content having been changed from homogeneity to heterogeneity, the recommendation becomes a more challenging issue. In this paper, we have investigated the recommendation problem on a general heterogeneous Web social network. We categorize the recommendation needs on it into two main scenarios: recommendation when a person is doing a search and(More)
We present the results from a mixed methods comparison of a tangible and a multi-touch interface for a spatial problem solving task. We applied a modified version of a previous framework to code video of hand-based events. This enabled us to investigate motor-cognitive strategies as well as traditional performance and preference constructs. Sixteen adult(More)
Despite a long history of using participatory methods to enable public engagement with issues of societal importance, interactive displays have only recently been explored for this purpose. In this paper, we evaluate a tabletop game called Futura, which was designed to engage the public with issues of sustainability. Our design is grounded in prior research(More)
StitchRV is a fiducial and touch-tracking engine based on the popular reacTIVision fiducial tracking system. StitchRV combines video input from multiple cameras in real time, and can be customized for a wide range of hardware and fiducial tracking applications through the high-performace rapid prototyping environment openFrameworks. The multi-camera(More)
Purpose: Despite favorable responses of chimeric antigen receptor (CAR)-engineered T-cell therapy in patients with hematologic malignancies, the outcome has been far from satisfactory in the treatment of solid tumors, partially owing to the development of an immunosuppressive tumor microenvironment. To overcome this limitation, we engineered CAR T cells(More)
With the tremendous development of mobile Internet and big data, much attention has been attracted on streaming data transmission. In this paper, we propose a quasi real-time transmission scheme using spatially coupled LDPC codes for forward error correction. Recursive encoder and sliding-window decoder with low-latency and low-complexity are employed for(More)
Target reporting plays an important role in firing accuracy test and exercitation of small arms. Since a long time, we have been relying on the traditional manually target reporting, whose disadvantage is big error and low efficiency. We construct a new automatic target reporting system by means of machine vision. It analyses the captured target image with(More)
Along the coast of Shandong Province in China, an extensive hatchery-release programme has been conducted for more than 10 years. However, no information has been reported concerning the long-term effects on the wild population resulting from the release of large numbers of juveniles in Portunus trituberculatus. In this study, sequence variation of swimming(More)
Spatially coupled low-density parity-check (LDPC) codes have attracted considerable attention due to their promising performance. Recursive encoding of the codes with low delay and low complexity has been proposed in the literature but with constraints or restrictions. In this manuscript we propose an efficient method to construct parity-check matrices for(More)
