These systems for automatic product handling and inspection have proven themselves successful—continued development of low-cost pattern recognition hardware promises many more such systems.
Major challenges must be tackled for brain-computer interfaces to mature into an established communications medium for VR applications, which will range from basic neuroscience studies to developing optimal peripherals and mental gamepads and more efficient brain-signal processing techniques.
With the emergence of smart phones, the time is fast approaching when devices small enough to fit in a pocket will be able to meet all our personal computing and communication needs. Despite their increased capabilities and functionality, however, the size and shape of today's computing devices - from laptops to handhelds - are still largely determined by the same factors. But as user interfaces become...
BCI systems let users convert thoughts into actions that do not involve voluntary muscle movement. The systems offer a new means of communication for those with paralysis or severe neuromuscular disorders. BCI technology is a relatively new, fast-growing field of research and applications with the potential to improve the quality of life in severely disabled people. To date, several BCI prototypes...
Refactoring for data locality opens a new avenue for performance-oriented program rewriting. SLO has broken down a large part of the complexity that software developers face when speeding up programs with numerous cache misses. Therefore, we consider SLO to belong to a new generation of program analyzers. Whereas existing cache profilers (generation 1.0) highlight problems such as cache misses, second-generation...
A digital library project aims to combine the look and feel of physical books with the advantages of online documents such as hyperlinks and multimedia. A lightweight open source implementation enables highly responsive page turning and works within standard Web browsers.
Computer-generated imagery (CGI) in films has advanced to the point that it's often difficult for viewers to figure out which scenes have visual effects in them. Two CGI effects that illustrate the state of the art are facial animation and fluid dynamics.
Computer game players have already set the agenda for future visual effects and techniques: One group seeks to enjoy movie-quality photorealistic games, while another seeks maximum freedom of interaction in an open, self-evolving, persistent virtual world.
Topics include a new programming language for visualization applications, an attachment that turns a mobile phone into a microscope, a technique that lets users receive high-bandwidth content over Wi-Fi connections, and the US's first green-IT college degree.
In 1988, 20 engineers at Apple Computer began to develop an object-oriented system code-named Pink. In 1992, the project moved to Taligent, a joint enterprise created by Apple and IBM and later joined by Hewlett-Packard.
The increasing availability and relatively low cost of digital data collection technologies have created a data avalanche for archaeologists, who are collaborating with computer scientists to develop new visualization and analysis tools. The Web extra is a video that demonstrates how researchers were able to visualize archaeological LiDAR data in the Calit2 NexCAVE.
In-vehicle gestural interfaces are easy to use and increase safety by reducing visual demand on the driver. Prototype capacitive proximity sensing and depth-camera-based systems demonstrate that current technologies can recognize finger and hand gestures of varying complexity.
Advances in speech-processing technology have enabled novel ways to learn a foreign language online. With Engkoo, researchers in China are working to turn any computer into a language learning assistant and make searching a language easier. The featured Web extra at http://youtu.be/_VHDMAKKLKo is a video discussion titled “Computer-Assisted Audiovisual Language Learning” that demonstrates Engkoo,...
An investigation of the technology and human factors that drive augmented reality research describes recent developments in handheld AR, concentrating on localization, tracking, interaction, and visualization, and offers several examples illustrating the vast potential and important applications of AR. A related video can be seen here: http://youtu.be/ol371rIyUFY. It shows several real-world examples...
Researchers are developing augmented reality visualization systems to provide accessible and user-friendly interfaces for medical intervention and patient information systems. A related video can be seen here: http://youtu.be/kifj0ZP4Mos. It shows how augmented reality visualization systems can provide accessible and user-friendly interfaces for medical intervention and patient information systems.
The increased degrees of freedom in a multitouch interface help users control 4D worlds with intuitive gestures. Relative to a specialized mouse-based interface, a multitouch interface is easier to learn, and 4D object manipulation is up to 1.5 times faster.
Businesses are increasingly using location analytics—which integrates organizational and geographic data—to help identify trends, develop more accurate predictions, and make better decisions.
Visualization and visual analytics re-searchers can contribute substantial technological advances to support the reliable, effective, safe, and validated systems required for personal health, clinical healthcare, and public health policymaking. The Web extra at http://youtu.be/KLlStIfGUZQ is a video showing how Oracle Health Sciences Institute is supporting research at the University of Maryland that...
