Autominder: an intelligent cognitive orthotic system for people with memory impairment

Dynamic consistency of fuzzy conditional temporal problems

“…CTPs (Tsamardinos et al , 2003) extend temporal constraint satisfaction problems (Dechter et al , 1991) by adding observation variables and by conditioning the occurrence of some events on the presence of some properties of the environment.…”

“…A CTP (Tsamardinos et al , 2003) is a tuple V, E, L, OV, O, P where P is a set of Boolean atomic propositions, V is a set of variables, E is a set of temporal constraints of the form l ij ≤ x i − x j ≤ u ij with x i , x j ∈ V and l ij , u ij ∈ ℜ, L : V → Q * is a function attaching conjunctions of literals in Q = {p i : p i ∈ P } ∪ {¬p i : p i ∈ P } to each variable in V , OV ⊆ V is the set of observation variables, and O : P → OV is a bijective function that associates an observation variable to a proposition. The observation variable O(A) provides the truth value for A.…”

“…Figure 5 shows an example of a CTP inspired from (Tsamardinos et al , 2003). The goal is to go skiing at station Sk1 or Sk2, depending on the condition of road R. Station Sk2 can be reached in any case, while Station Sk1, the most preferred, can be reached only if road R is accessible.…”

Algorithms for Smart Spaces

“…Remote monitoring systems have been designed with the common motivation that learning and predicting inhabitant activities is key for health monitoring, but very little work has combined the remote monitoring capabilities with prediction for the purpose of health monitoring. Some work has also progressed toward using typical behavior patterns to provide emergency notifiers or inhabitant reminders, which is particularly useful for the elderly and patients suffering from various types of dementia [39,40,[44][45][46].…”

Object Reminder and Safety Alarm

“…Autominder [3] is a project to support activity reminder and help clients remain their daily living activities, such as eating, performing hygiene, taking medicine and toileting. It keeps the client's activity model for further planning and has scalability for addition or modification of an activity.…”
