TLDR
A 3D deformable Point Distribution Model of the human hand is constructed, capturing training data semi-automatically from volume images via a physically-based model and how to improve on a weighted least-squares pose parameter approximation at little computational cost is shown.Abstract:
In this paper we first describe how we have constructed a 3D deformable Point Distribution Model of the human hand, capturing training data semi-automatically from volume images via a physically-based model. We then show how we have attempted to use this model in tracking an unmarked hand moving with 6 degrees of freedom (plus deformation) in real time using a single video camera. In the course of this we show how to improve on a weighted least-squares pose parameter approximation at little computational cost. We note the successes and shortcomings of our system and discuss how it might be improved.read more

Method and apparatus for integrating manual input
TL;DR: In this paper, a simple proximity transduction circuit is placed under each electrode to maximize the signal-to-noise ratio and to reduce wiring complexity, and segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contacts and extracts shape, position and surface proximity features for each group.

Visual interpretation of hand gestures for human-computer interaction: a review
TL;DR: A fraction of the recycle slurry is treated with sulphuric acid to convert at least some of the gypsum to calcium sulphate hemihydrate and the slurry comprising hemihYDrate is returned to contact the mixture of phosphate rock, phosphoric acid and recycle Gypsum slurry.

Mode-based graphical user interfaces for touch sensitive input devices
Steve Hotelling,Joshua A. Strickon,Brian Q. Huppi,Duncan Robert Kerr,Imran Chaudhri,Greg Christie,Jonathan P. Ive,Bas Ording +7 more
TL;DR: In this article, a user interface method for detecting a touch and then determining user interface mode when a touch is detected is presented. And the method further includes activating one or more GUI elements based on the user interface modes and in response to the detected touch.

Active shape models—their training and application
TL;DR: This work describes a method for building models by learning patterns of variability from a training set of correctly annotated images that can be used for image search in an iterative refinement algorithm analogous to that employed by Active Contour Models (Snakes).

Model-based tracking of self-occluding articulated objects
James M. Rehg,Takeo Kanade +1 more
TL;DR: This work describes a framework for local trading of self occluding motion, in which one part of an object obstructs the visibility of another, using a kinematic model to predict occlusions and windowed templates to track partially occluded objects.
