Memex Summit, July 2006 SenseCam & memory rehabilitation Georgina Browne, Emma Berry, Narinder Kapur Steve Hodges, Lyndsay Williams, Gavin Smyth, James Srinivasan, Alex Butler, Alban Rrustemi, Ken Wood
Memex Summit, July 20063 Causes and treatment of memory loss Neurodegenerative diseaseNeurodegenerative disease –Alzheimers disease and Lewy Body dementia can be treated with medication – with limited success –No medical treatment for other dementias –External memory aids (in theory) Acquired brain injury (traumatic and non- traumatic)Acquired brain injury (traumatic and non- traumatic) –External memory aids (in theory)
Memex Summit, July 20064 Improving memory with SenseCam Different types of memory:Different types of memory: –Episodic – things you have done (personal experiences) –Semantic – facts and concepts –Prospective – things you intend to do (go shopping, visit friends, make and keep appointments) Almost all memory aids treat prospective memoryAlmost all memory aids treat prospective memory
Memex Summit, July 20065 Improving memory with SenseCam Episodic memory critical to quality of lifeEpisodic memory critical to quality of life –Forms basis for semantic memories –Guides actions, creates bonds, builds self-concept SenseCam records experiencesSenseCam records experiences –Captures events from patients point of view –Without conscious thought or intrusion –Plays back quickly in simple-to-use, easy-to-view movie Subsequent viewing of image sequencesSubsequent viewing of image sequences –Cues recall & so consolidates storage of memories
Memex Summit, July 20066 Improving memory with SenseCam Cambridge Memory Clinic, Addenbrookes HospitalCambridge Memory Clinic, Addenbrookes Hospital 63 year old, well-educated, married woman Mrs B63 year old, well-educated, married woman Mrs B Diagnosed with limbic encephalitis in 2002Diagnosed with limbic encephalitis in 2002 Now has marked amnesiaNow has marked amnesia –usually no memory a couple of days after event
Memex Summit, July 20067 Improving memory with SenseCam Goals of patient and husbandGoals of patient and husband –To improve Mrs Bs episodic memory –To share experiences with each other –To improve Mrs Bs self-esteem and confidence
Memex Summit, July 20068 Improving memory with SenseCam Study ProtocolStudy Protocol –Experimental condition: SenseCam used to record special days (N=9) –Control condition: written diary used to record special days (N=3) –Baseline condition: no memory aid used to help recall special days (N=2) –Information reviewed every 2 days for 2 weeks –Memory evaluated before each review
Memex Summit, July 20069 ResultsResults Proportion of event remembered Memory of an event over time Baseline Days elapsed following event
Memex Summit, July 200610 ResultsResults Memory of an event over time Days elapsed following event Diary Baseline Proportion of event remembered
Memex Summit, July 200611 ResultsResults Memory of an event over time Days elapsed following event Diary SenseCam Baseline Proportion of event remembered
Memex Summit, July 200612 ResultsResults Memory of an event over time Days elapsed following event Diary SenseCam Baseline Proportion of event remembered
Memex Summit, July 200613 Results: SenseCam feedback Results from patients point of view:Results from patients point of view: –More relaxed socially and less anxious –Sharing experiences again was a sheer pleasure –Seeing images brings memories flooding back –It has enormous potential as a memory aid and has been a great success for us personally

Memex Summit, July 200618 Ongoing research: collaborative work Collaboration with Martin Conway, Professor of Cognitive Psychology, Leeds Memory Group, Editor of the journal MemoryCollaboration with Martin Conway, Professor of Cognitive Psychology, Leeds Memory Group, Editor of the journal Memory SenseCam is potentially the first truly powerful 21st century memory stimulant which could generally improve and strengthen memory in normal aging populations and in those with brain disease
Memex Summit, July 200619 Ongoing research: collaborative work Undertaking SenseCam memory studies based on two hypotheses:Undertaking SenseCam memory studies based on two hypotheses: 1.SenseCam movies mimic episodic memory VisualVisual From egocentric point of viewFrom egocentric point of view Temporally orderedTemporally ordered Formed outside awarenessFormed outside awareness Time compressedTime compressed Correspond to changes in goal-directed behaviourCorrespond to changes in goal-directed behaviour Using SenseCam in experimental studies Using SenseCam in experimental studies Investigating extent to which SenseCam stimulates recall and strengthens learningInvestigating extent to which SenseCam stimulates recall and strengthens learning Asking How do we forget over time? and How do our memories decline with age?Asking How do we forget over time? and How do our memories decline with age?
