Give a preliminary design for the mobile phone, Basic Computer Science

Assignment Help:

Question:

Imagine that you are part of a design team creating a new mobile phone for people such as "Angel White" whose persona is given below:

Angel is turning 90 years old this month and her grand-daughter, Mary, has decided to offer her a mobile phone for her birthday. Although Angel is not very at ease with technology, Mary thinks that a mobile phone is essential for her to be able to check on her grand-mother at anytime. Angel does not really see the need for this ‘little' phone since she has her own phone, a classic red phone with an analogue dial mechanism.

Angel likes to use her current phone to call her three children and her four favourite grand children. She also has written next to her phone, numbers such as the police station, her doctor and the fire services. Due to her age, it does happen that she drops object and has recently broken her transistor radio in that way.

(a) Create scenarios of usage ‘Angel' is likely to perform with the mobile phone.

(b) Give a preliminary design for the mobile phone explaining how it is optimized for this persona in these scenarios.
