Practice Questions

Question 1

When designing an interactive physical-digital product, which of the following best describes the concept of 'mapping' in Human-Computer Interaction (HCI)?

Question 2

A product needs to detect the force or pressure applied by a user's touch. Which of the following types of sensors would be most appropriate for this application?

Question 3

Consider a microcontroller that uses an 8-bit Analog-to-Digital Converter (ADC) with a reference voltage of $V_{ref} = 5V$. If an analog sensor provides an input voltage of $2.5V$, what digital value would the ADC typically output?

Question 4

In the context of integrating basic electronics and microcontrollers, what is the primary function of a 'pulse-width modulation' (PWM) signal?

Question 5

Which HCI principle focuses on minimizing the cognitive effort required by users to achieve their goals, often by making common tasks easy and obvious?
