Who am I?
Question
How many of you have heard about:
disruptive technology?
Disruptive technology
A disruptive technology or disruptive
innovation is an innovation that helps create a
new market and value network, and eventually goes
on to disrupt an existing market and value network
(over a few years or decades), displacing an earlier
technology there. [1]
Disruptive technology
Horse-drawn vehicles Early cars
Do you think that "early cars" should be considered
disruptive technology?
Disruptive technology
Horse-drawn vehicles FORD Model T
FORD Model T was a disruptive technology!
Disruptive technology
Cable-operated excavator
Hydraulic excavator
The hydraulic excavator was a disruptive technology!
Smartphones (1999)
• NOT yet a disruptive
technology
• NOT affordable
• NOT easy to use
Smartphones: Disruptive technology (2011)
Smartphones:
• disruptive technology• affordable• easy to use• changing how we:
• Communicate• Interact• Play/access music• Take pictures• Access information
My experience with smartphones
I Click I Talk:
The research driven AAC system for iPhone, iPadand Windows.
Perfect for all ages, all
communication disabilities
and all languages.
Background on Alzheimer's
Significance• Currently, 5.4 million Americans are affected with
Alzheimer's Dementia [2]
Science
• Alzheimer's is a neurodegenerative disease causing progressive decline in memory.
• The disease’s most frequent and recognizable symptom is memory loss associated with recent events [2]
Stages and Effects
• Three main stages: Mild, Moderate and Severe. • Patients suffer from increasing confusion,
disorganized thinking, impaired judgment, trouble in expressing themselves, and disorientation.
• Dependence on caregivers increases steadily to the point of becoming burden, affecting the quality of life of patients and caregivers [2]
Treatment• No permanent solution, but cuing patients about the
past events can reduce the rate of decline in memory [2]
Background on Alzheimer's
The capacity to remember recent events is linked to autobiographical memory, human memory responsible for archiving and recollection of specific personal experiences [3]
Autobiographical memory allows people to have a coherent tale of their personal experiences [4], a sense of self [5], and a ‘‘life history’’ to talk about with other people [6]
Loss of autobiographical memory causes confusion and frustration in patients with AD, and their caregivers have to step in to assist in the memory recall process
SenseCam
The SenseCam is a wearable digital camera that is designed to take photographs while it is being worn, without any user interaction
This specialized camera captures a picture every 30 seconds. These pictures are uploaded to a computer by a nurse and combined into a movie. The movie is then shown to the subject. The movie serves as a recap of the subject’s day

My personal experience with Alzheimer's
My grandmother (on my mother’s side)
1917 – 2008
• Healthy individual• Her memory (recent events)
started declining in 1990• Degenerated to no
communication in 2006• Increase burden on caregivers
(her 3 daughters)
Smartphone
• Samsung Blackjack
Flat surface less blurred images
Windows based
• iPhone does not allow taking picture automatically
Test idea: the smartphone was programmed to capture an image every 5 minutes by using the in-built camera
Daily life moments
Daily life moments
Research opportunity (2008)
Smartphone solution to capture daily life moments
The subject/caregiver uses a pre-stamped envelope to return the completed test and survey to the investigator
DVDs containing the final slideshows are mailed to the patient every week along with a satisfaction survey and a memory recall test
The images are automatically retrieved, date-stamped, combined into a slideshow, and burned onto a DVD
The subject carries the smartphone during the day, by way of the supplied lanyard, for 4 weeks The smart phone automatically takes pictures every 5 minutes during the day (8:00 a.m. to
8:00 p.m.) and uploads them to a secure server during the night (at 2:00 a.m.)
Subject
Patient at the Hampton Roads Neurophysiology Clinic,
located in Virginia Beach, Virginia
80-year-old, right-handed, married male in stage 4 of
the FAST scale (Mild
Alzheimer’s) [7]
Holds a master’s
degree and is a retired military officer
Familiar with the use of cell
phones
His caregiver was his wife, age 73, also a
college graduate. They had
been married for 54 years
Measurements
Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)
(before and after the interventions) [8]
Subject Satisfaction Survey
(once a week)
Recent events memory recall test
(once a week)
Methods
Subject Satisfaction Survey (once a week, Likert scale 1 to 5)
I feel comfortable wearing the smart phone around my neck
The smart phone is invasive
Seeing images from the slideshow brings back the memories of recent events
I feel less anxious knowing that the smart phone is recording what I am doing
I feel more relaxed in social situations because the slideshow will show me who I meet
Sharing past experiences through the slideshow with my family is a pleasure
Watching the slideshow helps me deal with daily tasks better
Recalling events with the help of the slideshow agitates me
Watching the slideshow with my family is boring
The slideshow has been a useful tool for my family
The slideshow has been a useful memory aid for me
The smart phone is easy to use
Methods
Recent events memory recall test (once a week, yes or no)
Results
Results
Subject Satisfaction Survey
The subject did not have any problem wearing the device
The subject considered the slideshow a useful tool for helping to live with persistent memory loss.
Results
It is possible to capture one's real life experiences without any involvement of the subjects.
Pictures collected do represent an ensemble of the important events occurred in the past.
Pictures from smart phones may indeed be used as an assistive device in the recall of recent events.
Limitations/problems
Case study with only one subject
Battery did not last the entire day
Subject forgot to wear the device (one day)
Smartcard was accidently disconnected (no pictures for a week)
Caregivers involvement is needed
Vision
No more DVD. Images will be made available on the web and subjects will look at them using tablets
Surveys available on-line
GPS capability
The smart phone (camera, data connection, and operating system) will be miniaturized and made available in the form of jewelry or a tie pin
