—Human activity recognition is a thriving research field. There are lots of studies in different sub-areas of activity recognition proposing different methods. However, unlike other applications, there is lack of established benchmarking problems for activity recognition. Typically, each research group tests and reports the performance of their algorithms(More)
A smart wheelchair can restore autonomy to patients with sensori-motor disabilities by enabling them to move around freely without depending on the care givers. The objective of a smart wheelchair is to reduce user effort in controlling the wheelchair and to ensure safety during movement. In this paper, our focus is to design and develop a smart wheelchair(More)
This paper presents underwater 3D capture using a commercial depth camera. Previous underwater capture systems use ordinary cameras, and it is well-known that a calibration procedure is needed to handle refraction. The same is true for a depth camera being used underwater. We describe a calibration method that corrects the depth maps of refraction effects.(More)
In today's digital media landscape, we are constantly surrounded by displays, from the LCDs found on the phones in our pockets to the ubiquitous screens that greet us whenever we enter a store, airport, taxicab, doctor's office, or educational institution. This plethora of displays both allures us and contributes to the media's saturation of our lives. The(More)
This paper proposes a generalized algorithm that enables mobile agents to meet in a bounded region based only on bearing information of other agents within their vicinity. Each agent repeatedly employs a stop-and-go strategy consisting of the following three actions: (1) Estimate the bearing of agents in its vicinity, (2) compute a target point based on the(More)
