About

Kajja is built from ground up keeping user experience in mind to improve users health. Kajja can detect the poses using OpenPose what exercise the user is doing with the use of Time delay Neural Network (TDNN). We help our users keep track of their fitness and exercise, all with a single touch of a button. Kajja keeps track of how many sets and repetitions of whatever type of exercise, without needing our users to interface with any UI.

Usage

Currently to launch the server, it requires the system to have nvidia docker running in the system as well as the use of a docker container for the server to run

docker pull nelsenew/openpose:cuda11

To run the docker container with GPU and GUI access, run the following shell script:

cd <path_to_this_repo>
./run_image_bash.sh

Before running this shell script, please modify line 22 to match the path to this repository in your local machine.

Once you are inside the interactive terminal of the Docker container, run OpenposeCamera.py:

python3 OpenposeCamera.py

This assumes that the ESP32-CAM is up and running, and streaming camera image via WiFi.

Problems

  • Obesity - a serious worldwide health issue.

  • People in normal time, have terribly hectic schedules, they do not have time to go to the gym. Some people are insecure about their bodies so avoid going to public gyms as well.

  • Work from home due to the recent COVID pandemic has deteriorated the situation.

  • Maintaining correct posture while exercising is essential, as wrong postures can lead to body problems.

  • Physical inactivity can lead to diseases, both physical and mental. In these trying times, any kind of disease can be deadly.

Proposed Solutions

  • We propose fitness such as gym as a solution to this issue. Doing gym helps reduce weight as well as cholesterol, thus this will be helpful for diabetics out there. Fitness and Gym also help reduces the symptoms of depression and anxiety.

Kajja is your real-time personal Gym instructor, allowing anyone to harness the benefits of gym from any place.

Kajja will ensure that however busy a person might be, they spend some time of their day in physical activity and mental exercises as they don't have to travel anywhere to exercise.

Current limitation

  • Only 3 exercises (dumbell-curl, push-up and squat) are supported by the application.
  • Voice assistant has not been implemented in the hardware.

Future plan

  • Creating an app into for a whole assistant for fitness in general.

  • Add personalized diets to assessing requirements and suggesting a whole fitness routine including food items, schedules, and fitness tracks and timings.

  • Add more exercise such as plank, sit-up, and more!
