Back-to-School Ergonomics: Healthy Habits for Backpacks, Homework, and Screen Time

When we think about ergonomics, we often think about adults in workplaces—lifting materials, working at computers, using tools or performing repetitive tasks. But many of the same ergonomic risk factors found in the workplace can also show up in a student’s day.

Force, awkward postures, repetition and prolonged or static postures can all be part of everyday school activities. A heavy backpack can increase the physical demands placed on the body. Looking down at a laptop or tablet can create sustained neck postures. Writing, typing and using a mouse can involve repetitive movements, while homework and screen time can keep students sitting in one position for extended periods.

Children and teenagers may not think of these activities as “work,” but their bodies are still responding to the physical demands of the tasks they perform.

The good news is that many basic ergonomic principles apply regardless of age. By reducing unnecessary physical demands, improving how tasks and equipment fit the student, and encouraging movement and changes in posture, parents and students can help make the school day more comfortable while developing healthy habits for the future.

Backpacks: Lighten the Load

A backpack may be one of the first places to consider ergonomics. Heavy loads, poor fit and carrying a backpack over one shoulder can increase stress on the back, neck and shoulders.

When selecting and using a backpack:

• Choose the right size. The backpack should be proportionate to the student’s body rather than oversized to accommodate more items.
• Use both shoulder straps. Two straps distribute the load more evenly than carrying a backpack over one shoulder.
• Adjust the straps for a close fit. The backpack should sit relatively close to the body rather than hanging loosely or low on the back.
• Use waist or chest straps when available. These can help stabilize the load, particularly with heavier backpacks.
• Pack strategically. Place heavier items closest to the student’s back and use compartments to prevent contents from shifting.
• Remove unnecessary items. Regularly cleaning out backpacks can prevent students from carrying books, supplies and other items they don’t need that day.

Pay attention to how the student handles the backpack, too. Placing a heavy backpack on a table or chair before putting it on can reduce awkward lifting from the floor.

Homework: The Kitchen Table Isn’t One Size Fits All

Students come in many different sizes, but most household furniture does not. A dining table that works reasonably well for an adult may leave a younger student’s feet dangling and shoulders elevated while writing or typing.

Ideally, a homework setup should allow the student to sit with the back supported, shoulders relaxed and feet supported. If the chair is too high for the student’s feet to reach the floor, a footrest—or even a sturdy box—can provide support.

Table height also matters. If the work surface is too high, students may elevate their shoulders or adopt awkward arm positions. If it is too low, they may bend forward excessively.

And while doing homework on a sofa or bed may seem comfortable, these positions often encourage prolonged slouching or awkward neck postures. A supportive chair and appropriate work surface are usually better choices for longer study sessions.

Laptops and Tablets: Watch the Neck

Portable technology presents an ergonomic compromise: when the screen is positioned well, the keyboard may be too high; when the keyboard is comfortable, the screen is often too low.

For brief tasks, this may not be a significant concern. For longer homework sessions, however, consider raising the laptop so the screen is closer to eye level and using an external keyboard and mouse. This allows the screen and input devices to be positioned independently.

Tablets and phones can create an even greater tendency to look downward. A tablet stand can reduce the amount of neck bending required for reading or watching instructional content.

The key is duration. An imperfect posture for a few minutes is very different from maintaining it for several hours.

Don’t Forget About Movement

One of the most useful ergonomic strategies doesn’t involve equipment at all: change positions and move. Even a well-designed workstation can become uncomfortable when someone stays in the same position for too long. Encourage students to periodically stand, stretch, walk around or switch tasks during longer homework sessions.

Rather than trying to maintain one “perfect” posture, encourage students to use a variety of comfortable postures throughout the day.

Writing, Reading and Other Schoolwork

Traditional schoolwork can create ergonomic concerns as well. Students frequently bend their necks and upper backs while reading, writing or drawing on a flat surface.

For longer reading assignments, raising a book or document on a bookstand can help reduce sustained neck bending. Students should also have adequate space for their materials, so they aren’t twisting or reaching repeatedly.

Lighting is another consideration. Poor lighting can encourage students to lean closer to their work or screen. Position task lighting so the work is easy to see while minimizing glare and reflections.

Ergonomics Is About Developing Good Habits

Parents don’t need to create a perfect miniature office for their children. Instead, focus on a few basic ergonomic principles:

• Keep loads manageable.
• Fit equipment and furniture for the student whenever possible.
• Keep frequently used items within easy reach.
• Reduce prolonged awkward postures.
• Encourage regular movement and changes in position.
• Pay attention when discomfort becomes persistent or repeatedly occurs during the same activity.

Computer Vision is Transforming Workplace Ergonomics: Lessons from Industry Leaders

At a recent ergonomics symposium, a panel of industry practitioners from Cargill, Michelin, and GE Aerospace shared their experiences implementing computer vision technology to enhance ergonomics programs. The discussion highlighted how these tools are helping organizations assess risk more efficiently, improve consistency, and accelerate workplace improvements while also addressing challenges related to implementation, training, and data privacy.

Why Organizations Are Turning to Computer Vision

A common theme among all three organizations was the challenge of limited ergonomics resources. Many facilities do not have dedicated ergonomists on site, leaving environmental health and safety (EHS) professionals, supervisors, athletic trainers, or other staff responsible for conducting risk assessments.

Panelists noted that traditional ergonomics assessment tools often require extensive training and can take months or even years to master. Computer vision systems help bridge this gap by making assessments more accessible, improving consistency, and enabling remote coaching and support.

Beyond efficiency, the technology provides a powerful way to communicate risk. Rather than presenting a numerical score alone, ergonomics teams can use video-based assessments to visually demonstrate workplace risks to managers and employees, making it easier to build understanding and support for improvement efforts.

Speed, Standardization, and Scale

One of the most significant benefits discussed was the dramatic increase in assessment capacity. Traditional manual ergonomics evaluations often take 60 to 90 minutes or more. Computer vision systems can significantly reduce that time, allowing organizations to assess more tasks and identify risks more quickly. One panelist shared that after implementing a computer vision platform, their organization completed more than 3,000 assessments in just five months.

The technology also helps standardize evaluations across multiple locations. Organizations can establish consistent assessment methods, compare results across facilities, and maintain centralized data that supports benchmarking and prioritization efforts.

For large organizations with dozens of facilities, this level of consistency provides visibility that was previously difficult to achieve with paper-based assessments and disconnected systems.

Securing Leadership Buy-In

Panelists emphasized that successful implementation requires strong leadership support. Most organizations began with pilot programs that demonstrated the value of the technology before expanding broader adoption.

Key factors that helped secure buy-in included:

• Demonstrating time savings and efficiency gains
• Showing measurable risk reduction
• Using before-and-after videos to visualize improvements
• Documenting ergonomics projects and outcomes
• Providing clear return-on-investment data

One organization grew from six participating facilities to more than 60 active sites after leadership recognized the value of having standardized assessments and centralized reporting across North America.

The Importance of Turning Assessments Into Action

A recurring message throughout the discussion was that assessments alone do not improve ergonomics. Panelists cautioned against using computer vision simply as a data collection tool. Instead, organizations must focus on implementing solutions and engaging employees in the improvement process.

Several companies established expectations that participating sites would complete ergonomics improvement projects on a quarterly basis. Progress was tracked through documented before-and-after assessments, helping ensure that identified risks translated into meaningful workplace changes.

The panel emphasized that employee engagement plays a critical role in sustaining momentum. Workers who are shown their assessment results and involved in developing solutions are more likely to support and adopt improvements.

Addressing Privacy and Employee Concerns

Data privacy and employee acceptance were major considerations during implementation.

Organizations addressed these concerns by:

• Clearly explaining that videos are used to evaluate tasks, not employee performance.
• Blurring faces automatically in all recorded videos.
• Restricting access to authorized personnel through secure systems.
• Establishing review and approval processes for sensitive work areas.
• Providing transparency regarding how data is collected, stored, and used.

Panelists reported that once employees understood the purpose of the technology and saw how it was being used to improve their work environment, resistance generally decreased and participation increased.

Lessons Learned During Implementation

The group shared several practical lessons from their pilot programs:

• Video quality matters. Poor lighting, unstable cameras, and obstructed views can reduce data quality.
• Camera positioning is critical. Side and 45-degree angles typically provide the most useful information.
• Users require training to understand both the capabilities and limitations of the technology.
• Organizations should avoid collecting large volumes of assessments without a plan for follow-up action.
• Management expectations and accountability should be established early.

Panelists also stressed that computer vision should not replace ergonomics expertise. Rather, it serves as a tool that supports trained professionals and helps less experienced users conduct more effective assessments.

Looking Ahead: The Future of Computer Vision in Ergonomics

While the panel was enthusiastic about the technology’s current capabilities, they also highlighted future opportunities. Areas of continued development include:

• Better integration of force measurement and fatigue assessment
• More advanced biomechanical modeling
• Improved prediction of musculoskeletal disorder risks
• Integration with machine vision and safety systems
• Enhanced analytics and predictive risk modeling powered by artificial intelligence

Several speakers noted that current systems excel at posture analysis but still rely on users to provide information such as force, load weights, and task frequency. Future advancements may automate more of these inputs, creating even more powerful risk assessment tools.

The panel’s message was clear: computer vision is not a replacement for a comprehensive ergonomics program, but it is rapidly becoming a valuable tool for organizations seeking to improve risk assessment, standardize processes, increase efficiency, and drive ergonomic improvements at scale. When combined with proper training, employee engagement, and a commitment to implementing solutions, these technologies can help organizations identify risks faster and create safer, healthier workplaces.
