Insider threats are one of the top security concerns facing large organizations

Posted on by Haptic

Current and former employees, business partners, contractors—anyone with the right level of access to a company’s data—can pose a threat. The incidence of insider threats has increased in recent years, at a significant cost to companies. Jingrui He, associate professor in the School of Information Sciences at the University of Illinois Urbana-Champaign, is addressing this problem Read more about Insider threats are one of the top security concerns facing large organizations[…]

Ultrasound system targets mouth to create virtual reality haptic effects

Posted on by Haptic

Lips are famously sensual but, together with the gums and tongue, they are also surprisingly sensitive, second only to the fingertips in nerve density. Researchers at Carnegie Mellon University have exploited this latter characteristic to devise a practical new way for people to receive tactile feedback in virtual worlds. Their system uses airborne ultrasound waves Read more about Ultrasound system targets mouth to create virtual reality haptic effects[…]

Business it’s not just fairness but it’s also trust

Posted on by Haptic

Increasingly, businesses rely on algorithms that use data provided by users to make decisions that affect people. For example, Amazon, Google, and Facebook use algorithms to tailor what users see, and Uber and Lyft use them to match passengers with drivers and set prices. Do users, customers, employees, and others have a right to know Read more about Business it’s not just fairness but it’s also trust[…]

How review ratings boost e-commerce

Posted on by Haptic

Recommender systems are used in e-commerce to guide consumers with messages like “People who purchased this item also purchased …” Past research has shown that these systems affect consumers’ choices and generally boost sales, but few studies have examined how product-specific attributes or review ratings influence the effectiveness of such systems. A new study sought Read more about How review ratings boost e-commerce[…]

Teaching the computer to teach

Posted on by Haptic

Intelligent tutoring systems have been shown to be effective in helping to teach certain subjects, such as algebra or grammar, but creating these computerized systems is difficult and laborious. Now, researchers at Carnegie Mellon University have shown they can rapidly build them by, in effect, teaching the computer to teach. Using a new method that Read more about Teaching the computer to teach[…]

Self-folding materials are quicker and cheaper to produce than solid 3-D objects

Posted on by Haptic

Researchers at Carnegie Mellon University have used an inexpensive 3-D printer to produce flat plastic items that, when heated, fold themselves into predetermined shapes, such as a rose, a boat or even a bunny. Lining Yao, assistant professor in the Human-Computer Interaction Institute and director of the Morphing Matter Lab, said these self-folding plastic objects Read more about Self-folding materials are quicker and cheaper to produce than solid 3-D objects[…]

Smart Walls React to Human Touch, Sense Activity in Room

Posted on by Haptic

Walls are what they are — big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used. Researchers at Carnegie Mellon University and Disney Research found that they could transform dumb walls into Read more about Smart Walls React to Human Touch, Sense Activity in Room[…]

Printing your own bioprinter

Posted on by Haptic

Researchers at Carnegie Mellon University have developed a low-cost 3-D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system. The researchers—Materials Science and Engineering (MSE) and Biomedical Engineering (BME) Associate Professor Adam Feinberg, BME postdoctoral fellow TJ Hinton, and Kira Pusch, Read more about Printing your own bioprinter[…]

Computational Design Tool Transforms Flat Materials Into 3-D Shapes

Posted on by Haptic

A new computational design tool can turn a flat sheet of plastic or metal into a complex 3-D shape, such as a mask, a sculpture or even a lady’s high-heel shoe. Researchers at Carnegie Mellon University and the Swiss Federal Institute of Technology in Lausanne, Switzerland (EPFL), say the tool enables designers to fully and Read more about Computational Design Tool Transforms Flat Materials Into 3-D Shapes[…]
