      <p>Preface</p>
      <p>The 12th International Conference on Indoor Positioning and Indoor
Navigation (IPIN 2022) was held in Beijing, China, on September 5-7, 2022.
This proceeding contains the Work-in-Progress Papers presented at IPIN 2022.
Launched in 2010 in Zurich, Switzerland, IPIN is a unique event entirely
dedicated to indoor localization, its applications and its development.</p>
      <p>Indoor navigation and positioning is called "the last mile" of navigation and
positioning, which involves many industries and fields such as transportation,
shopping and finance, special people care, safety production, etc. It is a hot
topic in the field of navigation and positioning in recent years, and is also one
of the key research directions in the fields of unmanned driving, 5G/6G, etc.</p>
      <p>The conference received 110 papers from about 120 universities, research
institutes and renowned companies worldwide. Each paper was reviewed by at
least two members of the Program Committee of the Conference and, on the
basis of their recommendations, 63 papers were accepted as Regular Papers
(RP) and submission to the IEEE Xplore Digital Library, while 31 were accepted
as Work-in-Progress (WiP) and submission to CEUR Workshop Proceedings.
Both RP and WiP were presented as oral presentations online, due to the
covid19 pandemic situation.</p>
      <p>IPIN 2022 hosted 2 tutorials, 5 Keynotes, 20 Parallel Sessions, including
5G positioning, geomagnetic navigation, acoustic navigation, and global
navigation satellite system (GNSS) indoor positioning, and is open to global
attendees through online conferences and webcasts. There were 185
attendees and nearly 16000 online free viewers during the conferences.</p>
      <p>The conference also held the 9th International Indoor Positioning and
Navigation Competition at the same time, which included 6 tracks such as 5G
positioning, UWB positioning and smartphone positioning, attracting 34 teams
from all over the world. Due to the covid-19 pandemic situation, the global
synchronous online competition mode was adopted for the first time,
demonstrating the highest level of the current international indoor positioning
and navigation field.</p>
      <p>IPIN 2022 awarded three Best Paper, one Best Presentation and six
Competition Track winners. Besides, selected papers have the opportunity to
send a technically extended version to the Special Issue "Indoor Positioning
and Indoor Navigation" by Springer’s Journal of Satellite Navigation.</p>
      <p>In addition, the world's first indoor positioning and navigation journal,
Journal of Indoor and Seamless Positioning and Navigation, sponsored by
IEEE, was inaugurated during the conference. The journal is currently the only
international academic journal focusing on the field of indoor navigation and
positioning.</p>
      <p>Thanks to all members of the IPIN 2022 Technical Program Committee for
their effort in the review process that was fundamental for maintaining the high
scientific level of the conference. Thanks to all members of Organizer
Committee for their hard work in making the meeting go on smoothly. Thanks
to all the researchers who supported this event by submitting their work and
actively participating in it. Thanks to all participants for their efforts to make IPIN
2022 a success.
