The ability of the user to "wake up" his laptop or tablet with just one phrase gives portable device chips presented by Intel.
As reported in a related publication MIT Technology Review, when o computer has been "awakened" (simply by a phrase like "Hello, computer"), it can be used as a virtual assistant controlled by voice, with the user giving it commands.
Tablets and light laptops based on the chip series Core M will go on sale later this year. They are capable of continuous "hearing" thanks to a core digital processor signalof (in digital signal processor core) that specializes in audio processing with high efficiency and minimal energy consumption.
"No matter what condition the system is in, it can still 'listen'," said Ed Gamsaragan, an engineer at Intel. "You can work on it or have it in standby."
The user can create a phrase with two or three words to "wake up" a computer with a chip Core M- while the system can be "trained" to respond to a specific one. Although voice-print is not safe enough to replace a code, it is able to prevent the system from being accidentally awakened, according to Gasharagan. As he adds, however, in combination with other biometric features, such as one webcam with facial recognition, a voice command could act as a mechanism security.
It is noted that the entire voice alarm feature is compatible with every operating system.
In the wider context of establishing "natural", alternative ways of controlling electronic devices, Matthew Reynolds's SideSwipe system also includes colleagues University of Washington, which allows a hand-held mobile phone to be handled, utilizing its signal: the radio waves are reflected back to the device, allowing gestures to be recognized.
As mentioned in a related publication of New Scientist, an algorithm is used that recognizes the unique reflections that occur when the user's fingers interrupt the "flow" of radio waves through which the mobile phone communicates with the mobile phone antenna. In tests done the program could recognize a series of movements with an accuracy of 87%. Its most notable feature is that it can also be used with non-smartphones, which means SideSwipe seems capable of bringing gesture recognition to countries in the developing world where smartphones are not yet widespread.
Extensive presentation of SideSwipe will take place at a conference in Hawaii in October.
