The study, conducted in conjunction with Prof. Jon Driver at University College London, revealed that the perceived direction of motion from a given visual object (in this case, red bars across a screen), depends on minute variations in the timing of an accompanying sound (a sequence of beeps, for example). This provides evidence that the brain’s integration of these visual and audio cues occurs at a very early stage of processing.
Every day examples of audio-visual integration include our ability to identify who is saying what in a noisy crowd and the illusion that sound comes directly from the an actor’s lips seen on a television, rather than from the loudspeakers; the latter is the well-known ‘Ventriloquist Effect’, where seeing influences the location of sounds.
The audiovisual illusion revealed by this new research could be dubbed ‘reverse ventriloquism in motion’, as it shows that sound affects what we see. This might explain why if we watch dancing without sound, the dancers appear to have no rhythm; and why the sound of a ball hitting a racket can help us to determine the direction of the ball in a game of tennis even though the ball moves faster that the camera or eye can track.
Dr. Freeman believes that his research could have profound implications for the understanding of the neural processes that underlie multisensory perception. This knowledge could be applied in a number of industries: “The illusion could be applied to novel displays that change their appearance depending on sound, which may be of use in advertising or providing an eye-catching multisensory warning or alert in safety-critical applications. It may also eventually be useful in detecting and diagnosing subtle perceptual differences thought to be characteristic of certain clinical conditions such as dyslexia and autistic spectrum.”

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
