• “Medisafe” and “My Pillbox”– Takes in drug description– Customize shape & color of drug

• Gap– Time for input– Human Error

Read My PillsWhat Is It?

Why was it selected?

Scan My PillsOriginal Idea

9

• Barcode Scanner– Database

• Health Insurance Portability and Accountability Act (HIPAA)– Different pharmacies, different barcode– Over-the-counter (OTC) medication

• Focus: long-term disease/conditions

Current Idea

• Working around HIPAA– Commonalities between medication– Texts and Labels

• Includes OTC and prescribed

How does it apply to smart health?

Smart Health

Research

• Center for Disease Control and Prevention (CDC): 2012– about 50% of adult population with one chronic disease/condition– about 1 in 4 have at least two or more

• Non-Adherence: about 31% – Forgetting to take medication is a large contributor– Results of non-adherence:

• 125,000 deaths per year• 80% increase of a chance of a heart attack

• Smartphones: more than 60%– Already used for reminders and daily life– Integral and simple solution to busy daily life

Platform, Language, Technology, and Tools

Platform & Languages

14

Android

“Read My Pills” was developed for the Android 4.0+, Jelly Bean. Currently, this application can be run on about 68% of all the Android Phones, as this is one of the most current versions. Testing for this application was run on Android 4.4, KitKat.

Languages & Technology

15

Android Studio

The development of this application was based in Android Studio 1.1.0. In Android Studio, the body of the code was written in Java while the GUI was developed in XML. Android Studio is similar to Eclipse, but provides more functions as it is used solely for application development for Android devices.

Tools

16

Tesseract OCR

A main component to writing the code for “Read My Pills” was the use of “Tesseract OCR.” “Tesseract OCR” is an open source code provided by Google Code which allows for character reading. Many contributors have worked together to help improve “Tesseract” as well as creating new libraries allowing it to read different languages correctly.

Usability Test

Participants

18

Usability Test

Due to time constraints, only five people were given the application to test out and play with. Another eight people were given the opportunity to be shown a demonstration of the application. Both groups were provided with tasks and asked to provide feedback. The testers were chosen within the College of Technology, but varied in major, while the observers were asked randomly. Here is the breakdown in majors for each group:

Observers:• Computer Information Technology• Computer Science• Pharmacy• Engineering• English• Chemistry

Testers:• Computer Information Technology• Computer Graphics Technology• Organizational Leadership and

Supervision• Engineering Technology

Tasks & Questions

19

Questions asked observers:• What would you like to see

add?• What do you think can be

improved?• What did you like?• What did you dislike?• Does it seem easy to use?

Tasks testers performed:• Try out the OCR• Try the photo function• Try to crash the program• Did anything perform in an

unexpected way?• Was the application easy to

use?

Usability Test

Results

Usability Test

• Overall Impression: Positive• What Worked:

– Idea of OCR– Camera for pill reminder– Existing Functions– User Friendly

• Flaws:– lacking functions necessary for real world usage– OCR showed inaccuracy in reading words– Aesthetics

Future Plans

Improvements

Future Planning

• Own library• Different Users/Individual Profiles

– Blood Pressure Record– Blood Sugar Record

• Autocomplete Textboxes• Database of Drugs• Aesthetics
