1 A New Digital Signage with Sensors: Experience and the issues Sungkwan Jung Jinhong Yang, Hyojin Park {sunupnet, JuYoung Youn

2 Dart Media & KAIST Dart Media The first-ever ad. sales representative for VoD services, covering IPTV, Digital Cable TV and Smart TV industries. Also Wi-Fi Ads, in-app Ads and Digital Signage Ads. Digital Information Displays have been installed in 22,000 apartment buildings in Seoul and Kyunggi. 2.2Millions KAIST(Korea Advanced Institute of Science and Technology) Institute for IT Convergence Conducting the Autonomous Smart Media Project with Dart Media from 2014 to 2016 Researching on the new commercial service scheme for Digital Signage while operating trial services. 2

3 Korean Digital Signage: Service Overview Digital signage based commercial ad. market on transportations, entertainments, and outdoor advertisement has shown their growth since Major outdoor commercial service/system providers: 교통매체 Transportation 엔터테인매체 Entertainment 빌보드매체 Billboard 기타매체 Others [Korean outdoor commercial sales trend*] E [Korean digital signage market forecast**] * Cheil worldwide(2013) ** kiwoom stocks, research center (2012) 3

4 Service and system requirements from the major digital signage service providers Requirements for Digital Signage Targeted commercial exposure Measurements for the exposure to effectiveness analysis Interoperability on heterogeneous H/W environments Linkage with mobile and customer devices Wide adaptability on the screen size by content size Cost-effective system build-up Particular content delivery for emergent situations Robustness operation along with legacy systems Mapping the requirements for Web environment Need to define metadata within the commercial to provide the information on their distributions Need a dynamic Tag to provide situation-aware service Need elements(or attributes) for tracking within the commercial Need new Device API to communicate with the digital signage device (can be added on the existing Device API) Extended functionality to carry the Web Objects (Beacon, Content PAN TM, etc.) Be able to provide targeted information using the distribution information within the contents metadata Need a Tag on the exposure to provide situation-aware service 4

5 Use case of the adaptive smart commercial delivery service for digital signage Commercial Campaign Page Situation #1 Advertiser Customized Web Browser Segmented Full-version Commercial Ad. Server Ad. Delivery System for Digital Signage Internet Customized Sensor APIs Camera Sensor Lux Sensor Humidity Sensor CO2 Temperature Sensor Sensor Situation #2 User Digital Signage User 5

6 Problem Statement The APIs to provide the sensor data from digital signage to the Web browsers The interfaces that enables the Web browser to access to the various sensors (camera, proximity, CO2, lux, temperature, humidity, etc.) Besides the APIs that has been dealt at the Device APIs WG, the standard interfaces that can support the content rendering on the public device environment like digital signage Description of content distribution condition for digital signage Ontology description for each content or segment which can be selectively exposed by the environmental conditions Interoperability with the legacy W3C Media Ontology to be able to interoperable with current Web [1] 6

7 Our Approach Metadata for Distribution Condition Name Type definition Description userobjcount (attname= minuserobjcount", attvalue= Integer"), (att Name= maxuserobjcount", attvalue= Integer") - Describe the expected number of users - Describe the recognized number of users from th e digital signage device userobjbehavior (attname= minuserobjbehavior", attvalue= Decimal"), (attname= maxuserobjbehavior", attvalue= Decimal") - Describe the motion data of expected users temperature (attname= mintemperature", attvalue="decimal"), (attname= maxtemperature", attvalue="decimal"), (attname= unit attvalue= String ) - Describe the expected temperature data. lux soundlevel co2 proximity (attname= minlux", attvalue="decimal"), (attname= m axlux", attvalue="decimal") (attname= minsound", attvalue="decimal"), (attname= highsound", attvalue="decimal") (attname= minco2", attvalue="decimal"), (attname= hi ghco2", attvalue="decimal") (attname= proximity", attvalue= String") - Describe the expected lux data. - Describe the expected level of sound data. - Describe the expected CO2 density data. - Describe the expected distance proximity data. 7

8 Suggestions Device APIs for emerging Ad. Devices Device APIs need to be extended to be able to support wide range of media, from various sensors to the new execution environment like digital signage. Metadata ontology for Ad. exchanges The metadata for environmental condition description and content distribution condition are also required. Cooperation with current WGs to keep the consistency and interoperability with legacy standards and technologies is needed as well 8
