Bare-hand human-computer interaction

Christian von Hardenberg, François Bérard
2001 Proceedings of the 2001 workshop on Percetive user interfaces - PUI '01  
Finger tracking and hand posture recognition are used to paint virtually onto the wall, to control a presentation with hand postures, and to move virtual items on the wall during a brainstorming session  ...  Barehanded means that no device and no wires are attached to the user, who controls the computer directly with the movements of his/her hand. Our approach is centered on the needs of the user.  ...  Labtec's Spaceball) and magnetic tracking devices (e.g. Polhemus' Isotrack).  ...

Visual touchpad

Shahzad Malik, Joe Laszlo
2004 Proceedings of the 6th international conference on Multimodal interfaces - ICMI '04  
Two downward-pointing cameras are attached above a planar surface, and a stereo hand tracking system provides the 3D positions of a user's fingertips on and above the plane.  ...  This paper presents the Visual Touchpad, a low-cost vision-based input device that allows for fluid two-handed interactions with desktop PCs, laptops, public kiosks, or large wall displays.  ...  ACKNOWLEDGEMENTS We thank Ravin Balakrishnan, Allan Jepson, and Abhishek Ranjan from the University of Toronto for valuable discussions.  ...

Interacting with Projected Media on Deformable Surfaces

Fitriani, Wooi-Boon Goh
2007 2007 IEEE 11th International Conference on Computer Vision  
We discuss its design and implementation within the context of a radically different approach for controlling home appliances by pressing virtual buttons that are projected on soft deformable surfaces  ...  such as a sofa pillow.  ...  Hand gestures may also be used as a selection action [15, 16] . However, the task of hand segmentation in unconstrained environment and poor lighting conditions is difficult. Freeman et al.  ...

Towards implicit interaction by using wearable interaction device sensors for more than one task

Hendrik Witt, Holger Kenn
2006 Proceedings of the 3rd international conference on Mobile technology, applications & systems - Mobility '06  
User interaction and context awareness are key issues in today's wearable computing research. Context-aware wearable devices typically use a multitude of special purpose sensors for this.  ...  In this paper, we show for a simple test case that even simple sensors in a wearable human computer interaction device can be used for robust context detection.  ...  To achieve this functionality a tilt-sensor and different micro-click buttons are used. GestureWrist [14] is a wrist-watch type input device.  ...

The Gesture Watch: A Wireless Contact-free Gesture based Wrist Interface

Jungsoo Kim, Jiasheng He, Kent Lyons, Thad Starner
2007 2007 11th IEEE International Symposium on Wearable Computers  
We introduce the Gesture Watch, a mobile wireless device worn on a user's wrist that allows hand gesture control of other devices.  ...  The Gesture Watch utilizes an array of infrared proximity sensors to sense hand gestures made over the device and interprets the gestures using hidden Markov models.  ...  The device needs to be large enough so that a user can press physical buttons or move a finger around a touch sensitive surface.  ...

Visual interpretation of hand gestures for human-computer interaction: a review

V.I. Pavlovic, R. Sharma, T.S. Huang
1997 IEEE Transactions on Pattern Analysis and Machine Intelligence  
In particular, visual interpretation of hand gestures can help in achieving the ease and naturalness desired for HCI.  ...  This has motivated a very active research area concerned with computer vision-based analysis and interpretation of hand gestures.  ...  The authors would like to acknowledge Yusuf Azoz and Lalitha Devi for their help with the references, and Karin Pavlovic for her help in reviewing the manuscript.  ...
