7. Persona-An Illustrative Case of ‘M’ Aim/Goals-
To be able to manage everyday
life activities without being
overseen
Frustration and pain point-
Difficulty in remembering recent
events such as conversations,
current tasks and family news
M is a 72 year old male who has early Alzheimer’s
disease. He lives in his own home with an elderly
Age- 72 years old
Sex- Male
spouse. He likes to go out into the community
Status- Early history of episodic unaccompanied. Some of his impairments are mild
memory problems. memory problems, spatial disorientation, difficulty
in finding the right words, taking some time to
Current solution: recognize that he is lost when he becomes lost,
- Caregiver/assistant
embarrassment in approaching others and asking
- Mobile phone
- Post-it reminders for directions, and inability to generate solutions.
These impairments are episodic (occur only
Problems with solution: occasionally).
- 24/7 assistance /expensive
- Limited application
- Unrealistic in situations

10. Requirements Acquisition
INTELLECTUAL
Severe memory problems
 One or a few simple action generation which
Confabulation
works for a variety of situations
Abstract thinking
Impaired judgment
 Device should be able to track progress relative to
Changes in personality
a previously entered task plan.
Distortions in recognition
Loss of initiative
 Help provided should include standard
components: what the current task is? What
actions are required to accomplish it? Where he
SOCIAL needs to go to accomplish the task?
Inability to recognize that  Must be unobtrusive and unlikely to attract the
