Project Idea

The idea of the project is to design andimplement a monitoring system fortreatment centers dedicated for mentally-retarded patients (Mr.P).

5/47

Project Idea


According to WHO:

Mr.P suffer from limited learning abilities anddefects in daily life skills (communication)

According to WHO:

Mr.P suffer from limited learning abilities anddefects in daily life skills (self-care)

Project Idea


According to WHO:

Mr.P suffer from limited learning abilities anddefects in daily life skills (community participation)

2


8/47

Project Idea


According to WHO:

Mr.P suffer from limited learning abilities anddefects in daily life skills with different levels ofretardation (mild (IQ=70) profound (IQ=20)).

2


9/47

Project Idea

According to PMRS ( 2006): Mr.P represent about 2.5% of the total population in

Palestine(reach 4% in Gaza).

Current trend is to integrate them in the society.

Real-time monitoring is required to provide themwith the needed support.
