Cognitive Inference Device for Activity Supervision in the Elderly

Algorithm 1

Algorithm for activity-inference from brainwave patterns in the elderly.

     ACTIVITY-INFERENCE (bwp)

          {

(1) input—brainwave pattern (bwp) from the elderly

(2) process—analyse bwp to infer activity and check activity fitness

(3) output—assist individual in ongoing activity, identify emergencies

  and perform needful actions

(4) = ; set of stored pattern types

(5) bwp: newly recorded pattern

(6) : activity fitness threshold in the elderly

(7) : fitness of ongoing activity

(8) activity: forecasted activity based on bwp pattern

(9) while (not dead brain)

(10) check {

(11) if (bwp = )

(12) then activity = “elderly individual in active judgments action”;

(13) elseif (bwp = )

(14) then activity = “elderly individual in working action”;

(15) elseif (bwp = )

(16) then activity = “elderly individual in undisturbed action”;

(17) elseif (bwp = )

(18) then activity = “elderly individual in pensive action”;

(19) elseif (bwp = )

(20) then activity = “elderly individual in sound asleep action”;

(21) else

(22) activity = “elderly individual in other actions”;

(23)    }

(24) /* identification of ongoing activity */

(25) determine dynamically for ongoing activity

(26) if ()

(27) then (“elderly individual fit for ongoing activity”)

(28) elseif ()

(29) then (“elderly individual may need some device assistance”)

(30) else {

(31) “elderly individual needs major device assistance”,

(32) “identify emergency services and perform needful actions”;
