The competition is aimed at bringing together the academic and<br>industrial research communities for evaluating different approaches and<br>envisioning new methods for indoor and seamless localisation, an area where no<br>generally accepted standards yet exist.<br><br>The competition builds on the experience of previous competitions and is based<br>on the EvAAL framework, ensuring experience, solidity and a well-founded<br>scientific method. The IPIN 2026 Indoor Localization Competition consists of<br>several Tracks:<br><br> • Track 1: Smartphone (onsite)<br> • Track 3: Smartphone (online)<br> • Track 4: Foot-mounted IMU (online)<br> • Track 6: Smartphone on vehicle (onsite)<br> • Track 7: 5G CIR with Sparse References (offline)<br><br>Results will be presented during dedicated sessions of the IPIN conference,<br>during which prizes will be awarded to the winners. Prizes are awarded for a<br>total worth to be announced.<br><br><br>ONSITE TRACKS<br><br>The onsite competition will take place in Roma, before the IPIN conference. An<br>actor carries the competing system by moving in the competition area. Competing<br>systems process data and provide position estimates in real time. Survey of the<br>area and system calibration is restricted to a single day, before the<br>competition proper.<br><br>Track 1 – Smartphone: An actor walks a mostly indoor route carrying the<br>competitor's smartphone which runs the competing system, using the sensors<br>available on the smartphones to identify the user's position.<br><br>Track 6 – Smartphone on vehicle: An actor carries a smartphone while walking a<br>mostly indoor route and driving along a partly indoors, partly outdoors with<br>impaired GNSS route, with the smartphone affixed to the car dashboard. The<br>smartphone sends sensors data in real time to a dedicated server, while at the<br>same time competitors get their data in real time from the same server.<br><br><br>OFFSITE TRACKS<br><br>Competitors in offsite competitions (online and offline) are provided with<br>sensors data and use them to estimate the user position. Competitors calibrate<br>their algorithms in advance using ground truth reference data (testing trials)<br>and compete using new unreferenced data (scoring trials). Scoring trials are<br>run on a Track-specific day.<br><br>Once testing trials are published, competitors can run them at their premises.<br>When the EvaalAPI server is made available, they must run the testing trials on<br>it. Scoring trials are provided to competitors only once they complete a run of<br>the testing trials.<br><br><br>ONLINE TRACKS<br><br>Competitors run their trials through the EvaalAPI in online mode to emulate the<br>causal, real-time behaviour of onsite Tracks. See the paper "Offsite evaluation<br>of localization systems: criteria, systems and results from IPIN 2021-22<br>competitions" for a conceptual overview.<br><br>Track 3 – Smartphone: A pedestrian walking under realistic conditions in<br>buildings with possibly small outdoor parts, using data provided by a<br>conventional smartphone.<br><br>Track 4 – Foot-mounted IMU: A pedestrian carries ULISS (Ubiquitous Localization<br>with Inertial Sensors and Satellites) on his foot while walking a path with<br>possible small outdoor parts. ULISS provides IMU, magnetic and pressure<br>readings plus GNSS data. No maps are provided.<br><br><br>OFFLINE TRACK<br><br>Competitors run their Trials through the EvaalAPI in offline mode, where<br>competitors download sensors data all at once and have a limited time to upload<br>all estimates at once.<br><br>Track 7 – 5G CIR with Sparse References: 5G CIRs are collected from eight<br>distributed antennas in a multipath-rich maintenance facility, with only a<br>sparsely labeled reference set, which can be addressed by pertaining or channel<br>charting.<br><br><br>TECHNICAL COMPETITION DETAILS<br><br>The evaluation criteria for the competition, restrictions on the accepted<br>technologies, technical rules and a description of the benchmarks are detailed<br>in the technical annexes to this call. Possible refinements of the annexes,<br>even based on applicants' comments, will be distributed on the competition<br>discussion mailing list <span class="Object" role="link" id="OBJ_PREFIX_DWT7748_ZmEmailObjectHandler"><span class="Object" role="link" id="OBJ_PREFIX_DWT7756_ZmEmailObjectHandler">contest@evaal.aaloa.org</span></span> and will appear on the<br>competitions site <<span class="Object" role="link" id="OBJ_PREFIX_DWT7749_com_zimbra_url"><span class="Object" role="link" id="OBJ_PREFIX_DWT7757_com_zimbra_url"><a target="_blank" href="https://competition.ipin-conference.org" rel="noopener" data-mce-href="https://competition.ipin-conference.org">https://competition.ipin-conference.org</a></span></span>>.<br><br>Competitors in online and offline Tracks get sensor readings and submit position<br>estimates through the EvaalAPI web service <<span class="Object" role="link" id="OBJ_PREFIX_DWT7750_com_zimbra_url"><span class="Object" role="link" id="OBJ_PREFIX_DWT7758_com_zimbra_url"><a target="_blank" href="https://evaal.aaloa.org/evaalapi" rel="noopener" data-mce-href="https://evaal.aaloa.org/evaalapi">https://evaal.aaloa.org/evaalapi</a></span></span>>.<br>The aim is to emulate a causal process similar to the data flow of an onsite<br>Track: input data can be read only once and only in sequence, and the timestamp<br>of each submitted position estimate is the same as the latest sensor reading.<br><br>All the data gathered by the competition committee during the competition,<br>including data produced by competing systems in online and offline Tracks, may<br>be published after the competition for the purpose of research and comparison.<br>Winners of the competition are announced on the IPIN web site and on the contest<br>mailing list.<br><br><br>COMPETITOR ADMISSION PROCESS<br><br>A competitor can be any individual or group of individuals working as a single<br>team, associated to a single or a number of organizations, who wants to<br>participate in one or several tracks.

Track<br>chairs will accept or refuse the application in a short time, based on technical<br>feasibility and logistic constraints.<br><br>After acceptance of the competitor's technical description, one member of the<br>competing team is required to register on the IPIN conference site, specifying<br>the Track to which the registration is linked. Full registration to the<br>conference covers participation in the competition process for one Track<br>(allotted time, support and space) and the submission of one paper describing<br>the system. Participation in additional Tracks can be added for an additional<br>fee. A reduced registration fee not including access to the conference is<br>available for online and offline Tracks.<br><br>Competitors who wish to test their onsite system which does not fit any of the<br>onsite tracks may ask chairs of Track 1 to be admitted off-track, which will be<br>granted subject to organisational constraints.<br><br><br>Be sure to subscribe to the contest mailing list to get updates on the<br>competition: <span class="Object" role="link" id="OBJ_PREFIX_DWT7752_com_zimbra_url"><span class="Object" role="link" id="OBJ_PREFIX_DWT7760_com_zimbra_url"><a target="_blank" href="http://evaal.aaloa.org/mailman/listinfo/contest" rel="noopener" data-mce-href="http://evaal.aaloa.org/mailman/listinfo/contest">http://evaal.aaloa.org/mailman/listinfo/contest</a></span></span><br><br><br>IMPORTANT DATES<br><br> ----------------------------------------------------<br> Technical annexes published: 1 Apr<br> Application opens: 1 Apr<br> Testing trials published (online, offline) 1 Apr<br> Application closes: 21 Sep<br> EvaalAPI server available: (online, offline) 1 Apr<br> Testing trial completed (online, offline) 15 Sep<br> Online and offline competition: 28 - 30 Sep<br> Onsite survey and sw integration (tentative): 4 Oct<br> Onsite competition (tentative): 5 Oct<br> Proclamation of winners: 8 Oct<br> ----------------------------------------------------<br><br><br>COMMITTEES<br><br>IPIN Competition committee:<br>Antonino Crivello – ISTI-CNR (IT)<br>Miguel Ortiz – GEOLOC Team, University Gustave Eiffel (FR)<br>Joaquín Torres-Sospedra – Universitat de València (ES)<br>Francesco Potortì – ISTI-CNR (IT)<br><br>Track chairs:<br>Track 1 Filippo Palumbo – ISTI-CNR (IT)<br> Davide La Rosa – ISTI-CNR (IT)<br>Track 3 Joaquín Torres-Sospedra – Universitat de València (ES)<br> Antonio R.
