Effects of IT and health
Evaluate how microprocessor-controlled devices affect home life and transport, and connect health risks from prolonged use to prevention.
Exam scope and assessment notes
Cambridge IGCSE Information and Communication Technology 0417, for exams in 2026, 2027 and 2028. Examples, datasets and practice are original StudyForA material; they are not Cambridge questions, source files, mark schemes or grades. Practical lessons teach transferable operations, but learners must perform them in locally available office and web-authoring software and inspect their own files. This site does not reproduce a Cambridge practical examination or award an official grade. The separate 2029 syllabus is not mapped here.
Before you begin
- No previous ICT course is assumed. Read each scenario carefully and justify a tool or method by connecting it to the task, user and constraints.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which risk is most directly linked to repeated prolonged keyboard or mouse movements?
What you will learn
- Evaluate positive and negative effects of smart devices in homes and transport, including data security, fitness, social interaction and safety.
- Explain causes and prevention of RSI, back problems, eye problems and headaches related to prolonged IT use.
Control can improve convenience and introduce risk
Microprocessor-controlled devices can monitor conditions, automate home tasks and support transport systems. Potential benefits include convenience, efficiency and safety alerts; possible costs include surveillance, data breaches, dependence on automation, reduced activity and less social interaction.
Autonomous vehicles and transport control can respond consistently to sensor data, but sensors may fail, decisions may be wrong and responsibility for safe operation still matters. Evaluate a named context rather than claiming that automation is always safer or always harmful.
Prevent strain before it becomes injury
Prolonged repetitive input can contribute to repetitive strain injury; poor seating and posture can contribute to back problems; glare, unsuitable viewing distance and long unbroken screen time can contribute to eye strain or headaches.
Prevention includes a correctly adjusted chair and screen, neutral wrist position, suitable lighting, regular movement breaks, varied tasks and reporting persistent discomfort. A break helps but does not make an unsafe workstation acceptable.

Pause and explain
A smart-home camera improves remote monitoring. What is the strongest evaluation?
Worked example
A delivery firm proposes driver-monitoring sensors and partially autonomous route control. Evaluate the benefits and concerns.
Show the worked solution
- Benefits could include consistent route data and alerts that help drivers notice hazards.
- Risks include sensor errors, personal-data exposure, overreliance and unclear action when the system fails.
- Judge the value against training, privacy controls, human oversight and fallback procedures.
Answer Monitoring can warn a driver about conditions and route automation may improve consistency. However, a faulty sensor or overreliance could create danger, while location records reveal personal behaviour. The system is useful only with safety-tested controls, clear data retention, driver training and a reliable human fallback.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A learner has wrist pain after long periods of typing. Identify a possible ICT-related health problem and propose three practical steps.
Give me a hint
Connect repeated movement with a named risk and change posture, breaks and input method.
Compare my reasoning
- Repeated keyboard use can contribute to RSI.
- Check keyboard and mouse position so wrists remain neutral.
- Take regular movement breaks and vary tasks; seek advice if symptoms persist.
The learner may be experiencing repetitive strain injury (RSI). Position input devices within easy reach, maintain a neutral wrist posture, take regular breaks and vary tasks. Persistent pain should be reported to an appropriate adult or health professional rather than ignored.
Look for these in your work
- Names RSI and its cause
- Gives practical prevention steps
Evaluate automatic lighting and temperature control in a home for an older resident.
Give me a hint
Balance comfort and accessibility against reliability, privacy and control.
Compare my reasoning
- Identify how automation can improve comfort or independent living.
- Consider sensor failure, data collection and the need for manual control.
- Recommend a safeguard that fits the resident's needs.
Automation can reduce the effort needed to adjust lighting or temperature and can support independent living. A sensor or network outage could leave a room uncomfortable, while occupancy records may reveal routines. Provide accessible manual controls, safe defaults and minimal data collection, then test the system with the resident.
Look for these in your work
- Balances a concrete benefit and risk
- Recommends an appropriate safeguard
A school computer room has screen glare and trailing cables. Propose actions that address eye strain and physical safety separately.
Give me a hint
Treat ergonomic comfort and trip/electrical hazards as different risks.
Compare my reasoning
- Reduce screen glare by adjusting display position and lighting.
- Secure cables away from walkways and inspect equipment.
- Set out movement breaks and safe-use routines.
For eye strain, position displays to reduce glare, adjust brightness and encourage breaks. For physical safety, route and secure cables away from walkways, avoid overloaded sockets and remove damaged equipment from use. The two risks require different controls.
Look for these in your work
- Separates the two hazards
- Matches controls to causes
Common mistakes
- Assuming a sensor warning guarantees safety
- Listing a health condition without explaining its cause or prevention
- Treating a positive or negative effect as universal
What can you explain now?
Name one workstation adjustment that can reduce eye strain and one that can reduce back strain.
Compare with the explanation
Position the display to reduce glare and set the chair so the user can maintain a supported upright posture.
Glare and poor viewing position contribute to eye discomfort; unsuitable chair and screen height can encourage poor posture and back strain.

Make it stick
Link prolonged input to one health risk and give one specific prevention strategy; then explain one benefit and one risk of smart-device monitoring.
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
