Perception

An experimental new dieting technology uses augmented reality to make food items appear la...

You might think that your feeling of satiation when eating is due simply to your stomach filling up. According to the Hirose Tanikawa Group at the University of Tokyo, however, the visual perception of food also has something to do with it – the greater the amount of food that a person sees that they’re eating, the sooner they feel full. With that in mind, the team has created a prototype dieting system that uses augmented reality to trick people into thinking their food items are larger than they actually are.  Read More

Disney's REVEL system applying virtual textures to  different areas of a teapot (Photo: Di...

Having long been successful with "talkies," Disney has developed technology that could allow the creation of "feelies." While designed more for touchscreens than the silver screen, the REVEL system developed at Disney Research uses reverse electrovibration to bring computerized control over the sense of touch, thereby allowing programmers to change the feel of real-world surfaces and objects without requiring users to wear special gloves or use force-feedback devices.  Read More

Last September, scientists from the University of California, Berkeley announced that they had developed a method of visually reconstructing images from peoples' minds, by analyzing their brain activity. Much to the dismay of tinfoil hat-wearers everywhere, researchers from that same institution have now developed a somewhat similar system, that is able to reconstruct words that people have heard spoken to them. Instead of being used to violate our civil rights, however, the technology could instead allow the vocally-disabled to "speak."  Read More

Anyone who regularly uses a video camera will know that the devices do not see the world the way we do. The human visual system can perceive a scene that contains both bright highlights and dark shadows, yet is able to process that information in such a way that it can simultaneously expose for both lighting extremes – up to a point, at least. Video cameras, however, have just one f-stop to work with at any one time, and so must make compromises. Now, however, researchers from the UK’s University of Warwick claim to have the solution to such problems, in the form of the world’s first full High Dynamic Range (HDR) video system.  Read More

Can Botox stunt your emotional expression?

A new study from the University of Wisconsin may have profound implications for the cosmetic-surgery industry. We all intuitively know there is an interaction between facial expression, thoughts and emotions and scientists have previously found that blocking the ability to move the body causes changes in cognition and emotion. In the latest UW tests, which involved the pinpoint administration of Botox to temporarily prevent frowning, it was found that facial expression also affects the ability to understand written language related to emotions. So using Botox …  Read More

The Popeye audio visual robotic head developed by the POP team

The ease with which human beings make sense of their environment through a range of sensory signals belies the complex processing involved. Approaches to give robots the same purposeful perception we take for granted have typically involved studying visual and auditory processes independently. By combining data from both sound and vision European researchers have developed technology that could facilitate robotic understanding and responses to human behavior and even conversations, bringing us closer to a future where humanoid robots can act as guides, mix with people, or use perception to infer appropriate actions.  Read More

Pray that this robot hand isn't out to get you.

Don't watch the video after the jump if you've recently seen a Terminator movie - because it's becoming clear that if the robots come after us, there'll be no stopping them. The video shows an incredible array of three-fingered robot hand/eye co-ordination exercises, including throwing and catching, spinning pens, tying knots and dribbling a ping-pong ball. The Ishikawa Komuro laboratory at the University of Tokyo put these videos together to demonstrate the incredibly quick parallel processing they are achieving with a mix of visual and tactile sensory inputs. Astounding stuff. Sarah Connor, you're in deep trouble.  Read More
