Here, the transfer function from speakers to listener is estimated and sound pressure extrapolated from an arbitrarily placed mic array. <\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">Dynamic sound zones rely on a large number of speakers. These need to be wireless to ease installation and allow portable units. However, as precise control of the signal at each speaker is required, and wireless network transmission of audio is highly error-prone, new network and audio signal coding algorithms need to be developed.<\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">Network coding will be optimized by modelling common transmission loss artefacts and gauging their effect on the sound zone. Audio coding will be made adaptive based on the state of the network, e.g. sacrificing control for robustness. Network and audio coding will be combined for adaptiveness and low delay, and to consider changes in the environment like room conditions, network topologies, and moving audio signals and listeners.<\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">Based on our research, and following the integration of software into several B&amp;O speaker products, user interaction with dynamic sound zones in ISOBEL will make use of input and output techniques within the natural user interaction (NUIs) paradigm. The sound zone system will be interactive through background sensing and foreground control.<\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">Important inputs are the location and emotional state of the listener. This will be detected with a range of sensors and used to develop a closed-loop interaction technique where sound zones optimize themselves (audio properties and content) to achieve an intended effect.<\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">A significant challenge of dynamic sound zones is that they are invisible and intangible and, therefore, difficult to control. Building on the demonstrated potential of NUIs, the ISOBEL approach is to make sound zones visible using AR (e.g. projection, LED, laser), and controllable through tangibles and speech. For this, techniques will be developed to control boundary conditions of the self-regulating sound zone system (e.g. desired effect and limits of operation) with an optimal user experience.<\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">To support a short timeframe for commercial sound zone products, the project will do sensing and interaction with existing consumer-grade technology, such as smartwatches, motion detection cameras, miniature projectors, and voice-based digital assistants. <\/span><\/p>\n<p><span lang=\"EN-US\" style=\"color: #333333;\">However, extending the ongoing work in HCI, user interaction research will also involve cutting-edge experimental in and output technologies with slightly longer time perspectives before being available in commercial products. These include shape-changing physical devices for combining in- and output in one medium, next-generation physiological sensors for more accurate measurements of the users\u2019 emotional state, and the use of pro-active digital assistants to nudge the user towards a desired behaviour.<\/span><\/p>\n<\/div><style type=\"text\/css\"><\/style><div class=\"fusion-title title fusion-title-2 fusion-sep-none fusion-title-text fusion-title-size-two\" style=\"margin-top:0px;margin-bottom:20px;\"><h2 class=\"title-heading-left\" style=\"margin:0;color:#066982;\"><b><span lang=\"EN-US\">Quality of Experience (QoE)<\/span><\/b><\/h2><\/div><div class=\"fusion-text\"><p><span lang=\"EN-US\" style=\"color: #333333;\">Development of the sound zone system relies on continual evidence on performance.

These will compare the effects of our sound zone prototype in different configurations against standard rooms, similar to the study of Wavecare\u2019s sensory delivery rooms, as reported in Nature [28].<\/p>\n<p style=\"color: #333333;\">Data on this will be collected through logging of patients\u2019 well-being and analysis of health records, combined with interviews with staff. Where possible, qualitative feedback from patients will also be received.<\/p>\n<p style=\"color: #333333;\">Home deployments are done with 15 households established through B&amp;O\u2019s user research department. These households will have experimental sound zone prototypes installed in their homes, integrated with their existing sound system setups. Users will then be free to use and experience the interactive sound zone system as part of their everyday lives. Data on this will be collected through logging of system use, physiological data, and interviews\/observations with 1-1\u00bd month intervals.<\/p>\n<p style=\"color: #333333;\">This will be combined with participatory design sessions where the families are encouraged to provide ideas on how they would like to interact with and use the system.<\/p>\n<\/div><div class=\"fusion-clearfix\"><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-fullwidth.fusion-builder-row-4 a:not(.fusion-button):not(.fusion-builder-module-control):not(.fusion-social-network-icon):not(.fb-icon-element):not(.fusion-countdown-link):not(.fusion-rollover-link):not(.fusion-rollover-gallery):not(.add_to_cart_button):not(.show_details_button):not(.product_type_external):not(.fusion-quick-view):not(.fusion-rollover-title-link) , .fusion-fullwidth.fusion-builder-row-4 a:not(.fusion-button):not(.fusion-builder-module-control):not(.fusion-social-network-icon):not(.fb-icon-element):not(.fusion-countdown-link):not(.fusion-rollover-link):not(.fusion-rollover-gallery):not(.add_to_cart_button):not(.show_details_button):not(.product_type_external):not(.fusion-quick-view):not(.fusion-rollover-title-link):before, .fusion-fullwidth.fusion-builder-row-4 a:not(.fusion-button):not(.fusion-builder-module-control):not(.fusion-social-network-icon):not(.fb-icon-element):not(.fusion-countdown-link):not(.fusion-rollover-link):not(.fusion-rollover-gallery):not(.add_to_cart_button):not(.show_details_button):not(.product_type_external):not(.fusion-quick-view):not(.fusion-rollover-title-link):after {color: #333333;}.fusion-fullwidth.fusion-builder-row-4 a:not(.fusion-button):not(.fusion-builder-module-control):not(.fusion-social-network-icon):not(.fb-icon-element):not(.fusion-countdown-link):not(.fusion-rollover-link):not(.fusion-rollover-gallery):not(.add_to_cart_button):not(.show_details_button):not(.product_type_external):not(.fusion-quick-view):not(.fusion-rollover-title-link):hover, .fusion-fullwidth.fusion-builder-row-4 a:not(.fusion-button):not(.fusion-builder-module-control):not(.fusion-social-network-icon):not(.fb-icon-element):not(.fusion-countdown-link):not(.fusion-rollover-link):not(.fusion-rollover-gallery):not(.add_to_cart_button):not(.show_details_button):not(.product_type_external):not(.fusion-quick-view):not(.fusion-rollover-title-link):hover:before, .fusion-fullwidth.fusion-builder-row-4 a:not(.fusion-button):not(.fusion-builder-module-control):not(.fusion-social-network-icon):not(.fb-icon-element):not(.fusion-countdown-link):not(.fusion-rollover-link):not(.fusion-rollover-gallery):not(.add_to_cart_button):not(.show_details_button):not(.product_type_external):not(.fusion-quick-view):not(.fusion-rollover-title-link):hover:after {color: #066982;}.fusion-fullwidth.fusion-builder-row-4 .pagination a.inactive:hover, .fusion-fullwidth.fusion-builder-row-4 .fusion-filters .fusion-filter.fusion-active a {border-color: #066982;}.fusion-fullwidth.fusion-builder-row-4 .pagination .current {border-color: #066982; background-color: #066982;}.fusion-fullwidth.fusion-builder-row-4 .fusion-filters .fusion-filter.fusion-active a, .fusion-fullwidth.fusion-builder-row-4 .fusion-date-and-formats .fusion-format-box, .fusion-fullwidth.fusion-builder-row-4 .fusion-popover, .fusion-fullwidth.fusion-builder-row-4 .tooltip-shortcode {color: #066982;}#main .fusion-fullwidth.fusion-builder-row-4 .post .blog-shortcode-post-title a:hover {color: #066982;}<\/style><div id=\"Subscribe\"><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-5 fusion-parallax-none nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\"  style='background-color: #000000;background-image: url(\"https:\/\/isobel.dk\/wp-content\/uploads\/2019\/09\/avada-podcasts-newsletter-background.jpg\");background-position: center top;background-repeat: no-repeat;padding-top:2%;padding-right:0px;padding-bottom:0px;padding-left:0px;margin-top: 0px;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;'><div class=\"fusion-builder-row fusion-row \"><div  class=\"fusion-layout-column fusion_builder_column fusion_builder_column_1_6 fusion-builder-column-11 fusion-one-sixth fusion-column-first 1_6\"  style='margin-top:0px;margin-bottom:0px;width:16.66%;width:calc(16.66% -
