This paper describes computationally and materially inexpensive methods for panoramic video imaging. Digitally combining images from an array of inexpensive video cameras results in a wide-field panoramic camera, from inexpensive off-the-shelfhardware. We present methods that both correct lens distortion and seamlessly merge images into a panoramic video image. Electronically selecting a region...

There has been a lot of discussion in recent years around the disappearing computer concept and most of the results of that discussion have been realized in the form of mobile devices and applications. What has got lost a little in this discussion is the moves that have seen the miniaturization of sensors that can be wirelessly attached to places and to humans in order to provide a new type of ...

There are many attempts to use the gestures for the natural human computer interface. Most of systems use the tracking devices to capture the human motion and display. In this paper, we propose a gesture recognition system for natural interface between the participant and his own avatar in virtual environment only using two polhemus sensors attached on the arm. Our system has two modes for the ...

background: according to clinical observations, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity, leading to structural and functional deficits in standing and walking. this study aimed at investigating the effect of foot hyperpronation on spine alignment in the standing position.   methods: thirty-five healthy males with an age range of 18-30 years partic...

Ever since the development of Computer Graphics in the industrial and academic worlds in the seventies, public knowledge and expertise have grown in a tremendous way, notably because of the increasing fascination for Computer Animation. This specific field of Computer Graphics gathers numerous techniques, especially for the animation of characters or virtual humans in movies and video games. To...

purpose: this study aimed to assess the effect of boston brace on trunk muscles length as well as lower limbs and trunk range of motion in patients with idiopathic scoliosis. methods: five patients with idiopathic scoliosis with c shape curve and mean (sd) age, height, and weight of respectively 12.61(1.16) years, 1.53(0.08) m, and 35.6(6.1) kg participated in this study. spatiotemporal paramet...

This paper is a practice and experience paper on the use of a low cost optical whole body motion capture system in combination with an ultrasound head tracker and a wide field of view head mounted display (HMD) that enables the user to visually replace his real body with that of a virtual humanoid or alien body. We describe the integration of the low cost Optitrack motion capture system with HA...

Virtual Pottery is an interactive audiovisual piece that uses hand gesture to create 3D pottery objects and sound shape. Using the OptiTrack motion capture (Rigid Body) system at TransLab in UCSB, performers can take a glove with attached trackers, move the hand in x, y, and z axis and create their own sound pieces. Performers can also manipulate their pottery pieces in real time and change arr...
