Intro to Interface Design

Suggest how you can gather user’s needs for a new mobile app.

• Conduct focus groups with stakeholders.

• Use interviews and questionnaires with target users.

• Analyze competitor apps for features.

• Create a social media poll for feedback.

Why should we include users in the design process?

• To make sure the system fits their needs.

• To reduce the overall cost of development.

• To speed up the design process.

• To limit user feedback during testing.

Why might a system fail if only expert users are included in testing?

• It may be too hard for new users who were not considered.

• Expert users may overlook basic functionalities.

• The system may be too simple for expert users.

• Testing with experts guarantees a flawless system.

Refer to a screenshot showing a file upload bar with percentage. What kind of feedback is this and why is it helpful?

• It is visual progress feedback that helps users know the system is working and how long it may take.

• It is auditory feedback that alerts users when the upload is complete.

• It is haptic feedback that provides a physical response during the upload process.

• It is textual feedback that describes the file size and type being uploaded.

What is one purpose of considering human factors in interface design?

• To enhance user engagement and satisfaction

• To make systems easier, safer, and more comfortable for users

• To increase the complexity of the interface

• To reduce the need for user training

Look at the login page screenshot that only shows 'Username' and 'Password' fields without any instructions. Suggest one improvement for novice users.

• Add instructions like ‘Enter your full email address’ and example text in the fields.

• Remove the 'Username' field to simplify the login process.

• Change the 'Password' field to a 'Show Password' toggle.

• Add a 'Forgot Password?' link below the fields.

Compare participatory design and user-centered design.

• Participatory design involves users directly; user-centered design focuses on their needs in all steps.

• Participatory design is only about aesthetics; user-centered design is about functionality.

• Participatory design is a one-time event; user-centered design is an ongoing process.

• Participatory design excludes users; user-centered design includes them in the final stages.

Give one real-world example of a consistent interface.

• Microsoft Office uses the same layout in Word, Excel, and PowerPoint.

• Adobe Photoshop has a uniform toolbar across all its features.

• Google Chrome and Firefox have identical bookmark management systems.

• Apple's iOS has a consistent design across all its applications.

Analyze how a ride-sharing app helps users complete tasks easily.

• Shows driver info, map, and estimated time clearly.

• Provides a chat feature for users to communicate with drivers.

• Offers discounts for frequent users.

• Allows users to book rides without an internet connection.

Your college app is slow during peak hours. What kind of requirement is this?

• Functional requirement

• Non-functional requirement

• User requirement
