Multimedia covers a wide range. In general, digital audio production, animation video production, website production, and even game development can all be attributed to multimedia. The definition of multimedia narrowly defined, that is, the project with interactive program development as the main object of this paper, such as interactive CD production, touch screen presentation production, etc. Of course, there will still be a lot of content related to graphic design, animation, video processing, audio production and so on. The application of multimedia technology in water conservancy and hydro-power engineering is characterized by a variety of media means to represent the design, construction process and post-construction scene of water conservancy and hydro-power projects and to simulate the phenomenon in the project, such as the performance of water conservancy and hydro-power projects. Hub layout, structure of main buildings, dam flood discharge, rubber dam dam overflow, sluice dispatching process, ship lock crossing process, etc. In the water conservancy and hydro-power project, computer multimedia technology has been widely used from the general design proposal to the entire pivot project demonstration system. This paper mainly introduces the design and development of the multimedia demonstration system for water conservancy and hydro-power projects. 相似文献

Wearable human‐interactive devices are advanced technologies that will improve the comfort, convenience, and security of humans, and have a wide range of applications from robotics to clinical health monitoring. In this study, a fully printed wearable human‐interactive device called a “smart bandage” is proposed as the first proof of concept. The device incorporates touch and temperature sensors to monitor health, a drug‐delivery system to improve health, and a wireless coil to detect touch. The sensors, microelectromechanical systems (MEMS) structure, and wireless coil are monolithically integrated onto flexible substrates. A smart bandage is demonstrated on a human arm. These types of wearable human‐interactive devices represent a promising platform not only for interactive devices, but also for flexible MEMS technology. 相似文献

We propose a novel application of an interactive and distributed system in medical consultation and education. The presented application uses a multiuser, collaborative environment with multimodal human/machine communication in the dimensions of sight, sound, and touch. The experimental setup, consisting of two user stations, and the multimodal interfaces, including sight (eye tracking), sound (automatic speech), and touch (microbeam pen), were tested and evaluated. The system uses a collaborative workspace as a common visualization space. Users communicate with the application through a fusion agent by eye tracking, speech, and microbeam pen. The audio/video teleconferencing is also included to help the radiologists to communicate with each other simultaneously while they are working on the mammograms. The system has three software agents: a fusion agent, a conversational agent, and an analytic agent. The fusion agent interprets multimodal commands by integrating the multimodal inputs. The conversational agent answers the user's questions and detects human related or semantic errors and notifies the user about the results of the image analysis. The analytic agent enhances the digitized images using the wavelet denoising algorithm if requested by the user. To evaluate the system, we used it for medical consultation on mammograms. Results also show that the relevant information about the region of interest of the mammograms chosen by the users is extracted automatically and used to enhance the mammograms 相似文献
