Problems with usability

System Fundamentals

Mobile Phones

- Problem: Small screen size.

 - Impact: Harder to read text, view images, or use touch-based controls.
 - Possible Cause: Examine how screen size affects user interaction in apps and websites not designed for responsiveness.

- Problem: Touchscreen sensitivity.

 - Impact: Mis-taps lead to unintended actions or navigation.
 - Possible Cause: Assess whether calibration issues or poor interface design lead to frequent input errors.

Laptops

- Problem: Trackpad usability.

 - Impact: Users find it difficult to control the cursor precisely.
 - Possible Cause: Determine whether low sensitivity settings or hardware design flaws cause inaccuracy.

- Problem: Overheating during prolonged use.

 - Impact: Device becomes uncomfortable or throttles performance.
 - Possible Cause: Explain how poor ventilation or inefficient thermal management in design contributes to this issue.

3. Tablets

- Problem: Heavy weight for prolonged handheld use.

 - Impact: Users experience physical strain while using the device.
 - Possible Cause: Investigate if material choice or size optimization can improve ergonomics.

- Problem: Limited multitasking functionality compared to laptops.

 - Impact: Reduces productivity for users needing multiple open applications.
 - Possible Cause: Justify whether this limitation stems from hardware constraints or software prioritization.

4. Smartwatches

- Problem: Small input area.

 - Impact: Difficulties in typing or navigating menus.
 - Possible Cause: Evaluate alternative input methods, such as voice or gestures, for improved usability.

- Problem: Short battery life.

 - Impact: Frequent charging reduces convenience.
 - Possible Cause: Explore how energy-intensive features, like constant connectivity, drain the battery.

Gaming Consoles

- Problem: Complex controller layouts.

 - Impact: New users struggle to remember button mappings.
 - Possible Cause: Discuss whether this complexity is due to game design or a lack of standardization.

- Problem: Online connectivity issues.

 - Impact: Players experience interruptions during multiplayer sessions.
 - Possible Cause: Examine whether server limitations or poor network code exacerbate this problem.

Standards

• Identify a range of usability problems with commonly used digital devices

Consider an argument or concept in a way that uncovers the assumptions and interrelationships of the issue.

Produce a plan, simulation or model.

Obtain the only possible answer.

Give a detailed account including reasons or causes.

Observe, study, or make a detailed and systematic examination, in order to establish facts and reach new conclusions.

Give valid reasons or evidence to support an answer or conclusion.

Assess the implications and limitations; make judgments about the ideas, works, solutions or methods in relation to selected criteria.

Undertake a systematic process of discovery

Offer a considered and balanced review that includes a range of arguments, factors or hypotheses. Opinions or conclusions should be presented clearly and supported by appropriate evidence.

a group or system of interconnected people or things.

Provide an answer from a number of possibilities. Recognize and state briefly a distinguishing fact or feature.
