Motivation and Background

Human Activity Recognition (HAR) has been a very active research field since it is the first step to monitor, diagnose, and cope with movement disorders [Daneault]. Rise of smartphones and wearable devices enabled many new embedded system solutions on these platforms. However, access to common set of experimental data has been a major obstacle that prevents breakthrough in this area. According to the International Technology Work Force on Parkinson’s Disease, two major technology barriers are lack of compatible platforms and isolated research efforts [Espay et al.]. We are organizing the First Embedded Human Activity Recognition (HAR) Design Contest to stimulate research and innovative solutions towards practical IoMT for health monitoring.

What is Provided to the Participants?

One of the major barriers to HAR research is access to labeled data sets. To this end, we developed an open source wearable IoT platform for health and activity monitoring [Bhat’19]. Using our prototype, we performed user studies with 22 users while they performed the following daily activities: Go down stairs, Go upstairs, Jump, Lay down, Sit, Stand, Walk. The following dataset from these experiments will be provided to the participants:
  1. Raw data from a 3-axis accelerometer placed at the right ankle
  2. Raw data from a stretch sensor placed on a knee sleeve
  3. Activity labels for the raw data
  4. Example features for each labeled activity window
  5. A baseline reference HAR classifier [Bhat’18] implemented in Matlab using this data
We provide precise time stamps and activity windows in contrast to coarse data sets collected by non-realtime platforms, such as smartphones. This is the only data set that has stretch sensors data. It is also one of the largest publicly available data sets.

What Should Be Submitted?

The goal of the contest is to design energy-efficient HAR classifiers. The participants can start either with the raw data (items 1-3 above) or use the example features provided to them (item 4 above), which will lower the barrier to entry. The designs can be submitted in one of the following categories:
Category-1: An embedded implementation on TI CC2650 MCU or a compatible IoT device
– Designs in this category will be evaluated based on classification accuracy, execution time per activity, and energy consumption per activity.
Category-2: An FPGA implementation
– Designs in this category will be evaluated based on classification accuracy, execution time, and area.
All submissions must include:

  1. A paper (up to 2 pages)* that describes the design and the results
  2. One slide executive summary
  3. The project source files (C, Verilog, or VHDL)

*The paper must be in PDF format and should not exceed 2 pages in ACM two-column format (9pt on 8.5″x11″ letter size paper). For formatting instructions and templates, please use the “ACM Proceedings templates: ACM Standard (sigconf)” available from the ACM web site.

Presentations at ESWEEK

The Design Contest presentations will be held on Tuesday (October 15th), 12PM-1PM during the poster sessions.
