A system for assessing the functional ability of a person to perform a task, the system comprising: a task identification unit adapted to receive one or more sensor signals and to identify the task to be performed by the person based on said received one or more sensor signals; a task complexity unit adapted to obtain a task-specific complexity signal representative of a required level of functional ability to perform the identified task; and a functional ability unit adapted to obtain a functional ability signal representative of a determined functional ability of the person, and characterized by further comprising: a risk analysis unit adapted to obtain a task-specific risk signal representative of a risk of the identified task, and an assessment unit adapted to determine an ability of the person to perform the identified task based on the task-specific complexity signal, the task-specific risk signal and the functional ability signal, and to generate an assessment signal representative of the determined ability of the person to perform the identified task, wherein the task-specific risk signal comprises information relating to both the person's perceived risk of the identified task, and a caregiver's perceived risk of the identified task; wherein the system is adapted to provide the generated assessment signal to at least one of: the person; a medical practitioner; and a caregiver; and wherein the task to be performed is taken from a group comprising: eating; cooking; medicating; sleeping; toileting; bathing; and washing. a task identification unit adapted to receive one or more sensor signals and to identify the task to be performed by the person based on said received one or more sensor signals; a task complexity unit adapted to obtain a task-specific complexity signal representative of a required level of functional ability to perform the identified task; and a functional ability unit adapted to obtain a functional ability signal representative of a determined functional ability of the person, and characterized by further comprising: a risk analysis unit adapted to obtain a task-specific risk signal representative of a risk of the identified task, and an assessment unit adapted to determine an ability of the person to perform the identified task based on the task-specific complexity signal, the task-specific risk signal and the functional ability signal, and to generate an assessment signal representative of the determined ability of the person to perform the identified task, wherein the task-specific risk signal comprises information relating to both the person's perceived risk of the identified task, and a caregiver's perceived risk of the identified task; wherein the system is adapted to provide the generated assessment signal to at least one of: the person; a medical practitioner; and a caregiver; and wherein the task to be performed is taken from a group comprising: eating; cooking; medicating; sleeping; toileting; bathing; and washing. a risk analysis unit adapted to obtain a task-specific risk signal representative of a risk of the identified task, and an assessment unit adapted to determine an ability of the person to perform the identified task based on the task-specific complexity signal, the task-specific risk signal and the functional ability signal, and to generate an assessment signal representative of the determined ability of the person to perform the identified task, wherein the task-specific risk signal comprises information relating to both the person's perceived risk of the identified task, and a caregiver's perceived risk of the identified task; wherein the system is adapted to provide the generated assessment signal to at least one of: the person; a medical practitioner; and a caregiver; and wherein the task to be performed is taken from a group comprising: eating; cooking; medicating; sleeping; toileting; bathing; and washing.
