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 the computer has "woken up" (just through a phrase like "Hello, computer"), it can be used as a virtual assistant voice-controlled, with the user giving commands.
Tablets and light laptops based on the chip series Core M will be available for sale at the end of the year. They are capable of continuous "hearing" thanks to a digital signal processor core (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 security mechanism.
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 mobile phone to be operated with gestures, harnessing its signal: radio waves are reflected back to the device, enabling gesture recognition.
As mentioned in a related New Scientist article, one is used algorithm που αναγνωρίζει τις μοναδικές ανακλάσεις οι οποίες προκύπτουν όταν τα δάχτυλα του χρήστη διακόπτουν τη «ροή» των ραδιοκυμάτων μέσω των οποίων το κινητό επικοινωνεί με την κεραία κινητής τηλεφωνίας. Σε δοκιμές που έγιναν το πρόγραμμα μπορούσε να αναγνωρίσει μια σειρά κινήσεων με ακρίβεια της τάξης του 87%. Το πλέον αξιοσημείωτο χαρακτηριστικό του είναι ότι μπορεί να χρησιμοποιηθεί και με μη «έξυπνα» phones, κάτι που σημαίνει πως το SideSwipe φαίνεται ικανό να φέρει την αναγνώριση χειρονομιών και σε countries του αναπτυσσόμενου κόσμου, όπου τα smartphones δεν έχουν σημειώσει μεγάλη εξάπλωση ακόμα.
Extensive presentation of SideSwipe will take place at a conference in Hawaii in October.
