Project Ergon aims at minimizing the ergonomic risks to construction workers using smartphone sensors and machine learning models.

• Ergonomics is the the science of designing a job to fit the workers’ physical capabilities, rather than imposing the job on a worker's body.

• MSDs are a group of disorders or injuries in a person's inner body parts (e.g. muscles, nerves, tendons, joints, cartilages, and spinal discs).
• Construction jobs are among the most ergonomically hazardous occupations which involve activities such as manual handling, heavy lifting, body twisting, and frequently working in awkward positions, all being potential causes of MSDs.

An awkward posture occurs if a person is not in his/her natural posture. Performing an activity in an awkward posture repetitively and/or for a long time can cause MSDs.

Overexertion occurs if a person applies too much force to perform an activty. Performing an overexerted activity for a long time and/or very frequently can cause MSDs.
