Multimodal interfaces development history is reviewed briefly in the introduction. Examples of applications of multimodal interfaces to education software and for the disabled people are presented, including interactive electronic whiteboard based on video image analysis, application for controlling computers with mouth gestures and the audio interface for speech stretching for hearing impaired and...
A multimodal corpus developed for research of speech recognition based on audio-visual data is presented. Besides usual video and sound excerpts, the prepared database contains also thermovision images and depth maps. All streams were recorded simultaneously, therefore the corpus enables to examine the importance of the information provided by different modalities. Based on the recordings, it is also...
This paper presents a new approach to diagnosing Parkinson's disease. The progression of the disease can be measured by the UPDRS (Unified Parkinson Disease Rating Scale) scale which is used to evaluate behavioral and motor symptoms of Parkinson's disease. Hitherto the evaluation of the advancement of the disease in the UPDRS scale is made by a specialist through medical observation. The authors suggest...
An innovative application of gaze-tracking and acoustic vector sensors (AVS) technologies for guidance of moving pan-tilt-zoom (PTZ) monitoring camera is presented. Gaze-tracking is used to steer and to zoom the camera to the gaze focus area. Additionally, it is combined with audio processing in two scenarios. First is called “audio slave”: directional acoustic monitoring is adjusted automatically...
In the paper a technique of eye tracking based on visible light is presented. The approach described does not require an additional hardware equipment used in the infrared eye tracking system. First, examples of existing eye tracking techniques were presented. Then, the proposed algorithm of image processing and the process of determining the eye position are described. The engineered eye tracking...
This paper presents the software part of an inexpensive hands-free eye tracking system. The system works using infrared illumination like most of the available eye trackers. Two methods allowing estimation the gaze point on computer screen are compared. Research on effectiveness of these methods is discussed and the better one is indicated.
