A new patent from Microsoft sheds light on improvements for the audio system for devices emulating an augmented reality. First spotted by us, the patent simply titled ‘Audio augmented reality system’ was published by USPTO on March 19, 2019, and filed by Microsoft in 2018. In the patent application, techniques to enhance the performance of audio augmented reality systems have been described. “Techniques for online information search and retrieval for a query including a digital audio waveform. In an aspect, an audio waveform is received and digitized by at least one of a plurality of audio input devices. The digitized audio waveforms are transmitted to a central processing unit, which formulates and submits a query to an online engine,” Microsoft explains. “The formulated query may include at least one digital audio waveform. The online engine retrieves one or more online results relevant to the formulated query. The online results may include one or more relevant visual results, and/or one or more relevant audio results. The retrieved results are served in real-time back to a user, via a device having audio output capability, and/or a device having visual data output capability,” the company adds. The foldable devices are in vogue this year. Companies like Samsung and Huawei have recently unveiled their foldable display mobile devices. Microsoft is also said to be working on its own foldable device and a new version of Windows optimized for such form factors. Follow along on OUR FORUM.
