Call for Competition

    Last Update
  • 09/Sep/2021

In 2014, IPIN organized the first yearly IPIN competitions, with a single on-site Track. From 2015 to 2020, the IPIN competitions included both on-site and off-site Tracks. All competitions were based on the EvAAL framework .

In 2021 the IPIN competition includes three off-site Tracks: see the Call for Competition below

Call for competitions

IPIN is pleased to announce the eight IPIN 2021 Indoor Localization Competition.
The  competition is  aimed  at  bringing together  the  academic and  industrial
research  communities for  evaluating different  approaches and  envisioning new
research  opportunities for  the indoor  localization area,  where no  generally
accepted standards exist yet.

The competition builds  on the experience of previous competitions  and is based
on  the  EvAAL  framework,  ensuring experience,  solidity  and  a  well-founded
scientific  method.   IPIN  2021  Indoor Localization  Competition  is  entirely
off-site.  It hosts three different Tracks:

    • Track 3: Smartphone (off-site)
    • Track 4: Foot-mounted IMU (off-site)
    • Track 7: Channel impulse response (off-site)

Competitors calibrate their algorithms in advance using a ground truth reference
database, and compete using new unreferenced data.

Track  3  - Smartphone:  A  pedestrian  walking  under realistic  conditions  in
multi-floor buildings using data provided by a conventional smartphone.

Track 4 - Foot-mounted IMU: A pedestrian carries ULISS (Ubiquituous Localization
with Inertial  Sensors and  Satellites), a state-of-the-art  Inertial Navigation
System producing IMU data, MAG data, PRESSURE data & GNSS data, without the help
of any maps.

Track  7  - Channel  impulse  response:  People with  UWB  tags  move through  a
cluttered industrial indoor environment in LOS and NLOS conditions.


The  evaluation  criteria for  the  competition,  restrictions on  the  accepted
technologies, technical rules  and a description of the  benchmarks are detailed
in the technical  annexes to this call.  Announcements  and possible refinements
of the annexes,  also based on applicants' comments, will  be timely distributed
on  the competition  discussion  mailing list and  will
appear on the EvAAL web site .

The organising  committee plans to  provide a  web service for  obtaining sensor
readings and submitting position estimates.  The  purpose is to emulate a causal
process similar to  the data flow of  an on-site competition: input  data can be
read  only once  and  only in  sequence,  and the  timestamp  of each  submitted
position estimate must be the same of the latest sensor reading.

All  the data  gathered by  the  competition committee  during the  competition,
including  data produced  by  competing  systems, will  be  published after  the
competition  for  the  purpose  of  research and  comparison.   Winners  of  the
competition will be announced on the EvAAL and IPIN web sites and on the contest
mailing  list.    Scientific  publishing   opportunities  will  be   offered  to


A competitor can be  any individual or group of individuals  working as a single
team,  associated to  a single  or  a number  of organizations,  who applies  to
participate in one or several Tracks.   Only one team from the same organisation
(laboratory) is allowed to compete in any number of Tracks.  Registration to the
competition is included in the registration of  at least one team member for the
IPIN 2021 conference,  and counts as a  single paper or poster  published at the
conference.  Alternatively, registration  to the competition costs  100€ for the
first Track  plus 50€  for any  additional Track,  to be  paid when  results are
