Question

Assume that you need to design a system that maintains a record of your body temperature measurements taken at different times to track fever etc. The system may include one or more parts/subsystems.

Question1:

What would be the major components of your designed system ? Explain them briefly. You may also draw a diagram illustrating the form factor of your components as you’ll design them

Question2:

One of the most important part of the design process is estimating the mental model of the user . Based on the form factor you designed in the question above , please describe the mental model of your product , while clearly illustrating the components of the mental model. Please use diagrams where necessary.

Question3:

Are there any activities that you may recommend to your design team , to refine the mental model you came up in the question above ?

Question4:

Based on your initial design , what are some of the common errors that you can foresee the user committing while using your product. Please classify the errors and explain how you may be able to avoid these errors by refining your design.

Question5:

What activities can you recommend to unearth more errors that the user may commit while using your product ?

Question6:

Briefly elaborate seven flavors of context for your proposed system design.

Answer 1

Ans 1. Major components of a temperature control system are 1st Personal information 2nd measurements 3rd records IV charts and graphs

Ans 2.

The personal info part will be saving the information about the person like his or her name age height weight

The second entity which we have chosen is measurements in this we will record the temperature of the person as well as pulse.

III entity is records which will display the temperature which we have noted earlier along with the date and time at which it was noted

And last IV entities charts and graphs which will show the temperature of a person weekly or monthly along with the graphs and charts so that fever can be easily checked

. Ans . 3.System should provide an option to select either Celsius or Fahrenheit to record the temperature

If statistics are not normal means temperature is high continuously then app should suggest person to visit doctor..

Ans 4. User may enter some out of bound or impractical values like body temperature 15℃ or 30 Fahrenheit .

Ans 5. app should be able to tackle these above kind of error. So app should provide an option for selecting the temperature values instead of entering those values.
