Zooming and Tunneling in Tioga: Supporting Navigation in Multidimensional Space
Zooming Tunneling Tioga Supporting Navigation Multidimensional Space
2016/5/24
In [7] we proposed a visual programming system called Tioga. The Tioga system applies a boxes and arrows programming notation to allow nonexpert users to graphically construct database applications. U...
Navigation and Coordination Primitives for Multidimensional Browsers
Data browsing hypermedia magnifying glasses user interfaces
2016/5/24
This paper describes extensions to the Tioga flight-simulator browsing protocol presented by Stonebraker et al. (1993a). These extensions allow users to navigate a multidimensional data space using so...

2016/2/29
Mobile navigation is usually focused on car navigation which implies a limitation on a street network. Due to this, route instructions in
most systems are based on distances and directions given by t...
Low Power Global Navigation Satellite System (GNSS) Signal Detection and Processing
Low Power Global Navigation Satellite System (GNSS) Signal Detection Processing
2015/6/29
The ability to detect and process weak Global Navigation Satellite System (GNSS) signals is extremely valuable as the specified received power levels of such signals are already quite low. For example...
Indoor Navigation System for the Visually Impaired with User-centric Graph Representation and Vision Detection Assistance
Indoor Navigation System Visually Impaired User-centric Graph Representation Vision Detection Assistance
2014/12/8
Independent navigation through unfamiliar indoor spaces is beset with barriers for the visually impaired. Hence, this issue impairs their independence, self-respect and self-reliance. In this thesis I...

基于图像旋转投影的导航路径检测算法（Navigation Line Detection Arithmetic Based on Image Rotation and Projection）
联合收获机 自动导航 图像处理
2009/9/11
提出一种农业车辆视觉导航路径识别算法——旋转投影算法。该算法通过角度枚举对图像ROI实施旋转变换，由旋转后图像的列均值与枚举角度构成旋转投影矩阵R，对其行向量实施差分运算得到差分旋转投影矩阵Rd，由Rd的极值可确定图像导航路径，即航向偏差θ与航位偏差d，进而可以求得世界坐标系下的导航路径参数。同理可以对田头线进行检测。为了提高算法的实时性，提出设定合理的ROI、实施线性压缩、旋转角度先粗分再细分的...
