Microsoft Indoor Localization Competition - IPSN 2015

Accurate indoor localization has the potential to transform the way people navigate indoors in a similar way that GPS transformed the way people navigate outdoors. Over the last 15 years, several human-centric approaches to indoor localization have been proposed by both academia and industry, but we have yet to see large scale deployments. This competition aims to bring together real-time or near real-time indoor location technologies and compare their performance.

Official Results

28 teams out of the 48 teams that submitted an abstract actually showed up in Seattle for the competition. 5 teams faced technical difficulties that prevented them from getting evaluated. As a result, 23 teams were actually evaluated. The average localization error across all 20 evaluation points for each team can be seen below:

=================================================================

We are happy to announce that we have received 48 submissions from 44 teams this year!

Overall, 12 submissions are fully authored or co-authored from industry people. From these 12 submissions, 4 come from startups in the indoor location space. The rest 36 submissions come from academia from all over the world.

There are 30 submissions in the infrastructure-based category (systems that need to deploy custom hardware) and 17 submissions in the infrastructure-free category. However, we are considering introducing additional categories for this year’s competition. The categories and the teams within each category will be announced on this website within the next couple of days.

All submissions have been assigned to one of two categories depending on the requirement to deploy custom hardware or not. The list of all submissions in each category can be seen below. Additional categories could be created depending on which/how many teams will actually attend the competition.

Teams in green fonts have at least one member that has officially registered for the competition. These teams will be allowed to compete. Teams in red fonts do not have any members officially registered for the competition yet. All teams in red fonts will not be allowed to compete unless at least one team member officially registers for the competition. The data below will be updated periodically. Latest update: April 12th 2015.

Call for Contesters

Eligibility:

Both academia and industry submissions are encouraged. All location techniques, such as ranging, fingerprinting, infrastructure, or device free, are welcome, except those that require end users’ manual measurements. Contesters can deploy their own infrastructure of up to 10 devices. Normal RF interference is expected, but no jammers for other deployments are allowed. The results must be shown on a portable device, such as a phone or a tablet/laptop that a person can easily carry around.

Demo submissions that do not meet one or more of the guidelines above will be included in the poster session and will be evaluated as a regular submission, but they will not be considered for prizes.

The competition will take place if at least 5 teams respond to this preliminary call for competition.

Competition Categories:

Depending on the nature and number of submissions multiple categories might be defined based on the accuracy (i.e., point-based vs. area based), the size, the cost, or the type (i.e., software vs. hardware) of the proposed solution. The final set of categories will be announced after the registration deadline.

Poster Session:

A poster session dedicated to all competition participants will be organized during the conference. Participants will have the opportunity to explain their system to conference attendees.

Evaluation and Prize:

Results are judged based on both room/zone level accuracy and absolute accuracy, and an award will be given for the top 3 teams in each category. When accuracy ties, infrastructure requirements will be used for tie breaking. The winning team in each category will be invited to present their approach at the conference, and receive a cash award.

Submission Guidelines:

Contesters must submit an abstract describing their approach and deployment requirements by the contest registration deadline. Submissions are treated as confidential until the competition. Submissions must be at most two (2) single-spaced 8.5" x 11" pages, including figures, tables, and references. Submission should follow the exact same format as regular, full IPSN 2015 papers. Abstracts should include the names and affiliations of authors. Templates can be found here: http://ipsn.acm.org/2015/submissions.html

Submission and Registration Deadline:

  • Contest Registration and Abstract Deadline: January 15, 2015, 11:59 pm EST.
  • To register for the competition, please email your abstract to dlymper@microsoft.com with the following subject line: 2015 Microsoft Indoor Localization Competition Submission.
