14. Saugus, MA

17. Kowloon app Everyone wants to have or think they need an app – like web

18. Mobile design is the entire experience • Having a need and/or learning about an app • Deciding to download • Deciding to try - initial use • Sustained or ongoing use • Participatory or shared use • Not a continuum • May be dips • Can an app be successful with only initial or sporadic use? • Are incentives necessary and which work? • Is trust necessary and at which point(s)? • How is health different from commerce or entertainment?

19. Pre-downloaded Signs on doors App stores Search based on categories, cost, featured, etc. Easier for iPhone because similar to iPod music? Android Market to Google Play Many of these provide ratings and reviews Participation is spotty Review sites Recommendations and word-of-mouth Ads, pop-ups, product packaging, TV, etc. How do people learn about apps?

Accomplish something otherwise not possible Accomplish something more easily than before Convenience Integrate disparate aspects of life Smart and/or innovative Why do people decide to try an app?

21. Designing mobile user experience • Smartphone capabilities • Also limitationsrelative to desktop/laptop • Smartphone layout and patterns • De facto standards are emerging • Apps are changing what people do

22. Smartphone in contrast to desktop/laptop • Screen size and proportions • Less screen real estate and more variety in screen proportions • Direct interaction with screen • No mouse so no roll-overs or tool-tips • Only some have keyboard so users interact directly with the screen • Variable orientation • Quick orientation switching • Single-screen environment • Hard to use multiple apps simultaneously even when possible • Established device standards • As market matures, consistent UI patterns are forming • Limited resources • Smartphones are limited by connection quality, battery life, processing power, and onboard memory

23. Touchscreen inputs • Touchscreen inputs include: • Single tap: used in place of a standard mouse click • Drag: scrolling or panning • Flick: scroll of pan quickly • Swipe: make selection, evoke a contextual menu, or as part of a two step process like delete • Pinch (open & close): zooming in/out • Press and hold: make a selection or evoke a contextual menu

Smartphone controls and capabilities • Smartphone controls and capabilities for input/output • Visual: high resolution screen • Audible: speaker, headphone jack • Physical: vibration for alerts, haptic feedback • Dedicated keys: Volume control, Back, Search, Menu, Power/Lock, Home • Physical keyboards: shortcuts, text input • Accelerometers: track motion and orientation • GPS • Backlight • Microphone: voice commands, ambient audio, music • Camera: photos and visual codes

25. Mobile design patterns: de facto standards have emerged • Activity Feeds • Check-in Screens • Comment Detail • Custom Tab Navigation • Dashboard Navigation • Edu Walk-Throughs • Empty Data Sets • Find Friends • Grouped Table Views • Lists • Maps • Notifications • Search • Settings • Sign Up Flows • Splash Screens • UI that I Heart • User Profiles • Venue Detail

26. Mobile design patterns for navigation • Important because it is the most visible screen and therefore needs to be appealing and usable • Springboard (Facebook) • Simple or expanding list menu (Blackboard) • Tab menu (Foursquare) • Gallery (Android gallery) • Dashboard • Metaphor

27. Design rules apply – even more so • Make first experience positive • Make subsequent experiences helpful and compelling • Consistency between screens • Similar metaphors to other apps, as appropriate • Well-written text • Judicious use of imagery • Name and branding • Creative use of mobile capabilities!

29. 4 dimensions of mobile design

30. Opportunities through social networking SMS/texting Mobile browser Apps Smartphone use for health

31. Social mobile health • Managing health habits involves managing social relationships, not just targeting a specific health behavior for change - Bandura • Mobile devices have increased the ways in which individuals can access, receive, and provide social support • Is facilitation of social support through mobile devices enough?

32. Mobile health interventions • Mobile browser use • Voice and text messaging interventions have been shown to • Increase quit rates among smokers • Motivate healthy eating and physical fitness • Facilitate self-management of asthma and diabetes • Interventions to record/send personal health data to a provider using mobile phone improved treatment adherence for diabetes, asthma, and cancer patients • Issue with where responsibility lies • Research suggests that patient attitudes regarding this type of intervention are relatively positive

33. Mobile access to health information • 2/3 of mobile users used browsers instead of apps to find health information

34. Who uses health apps? • Individuals with varying • Demographics • Health literacy skills • Health needs • Medical knowledge and experience • Skills • Disabilities • Cultural and language differences • Economic situations

35. Future growth • More than 44 million mobile health apps will be downloaded in 2012; more than 142 million by 2016 (Juniper Research) • Market for mobile health technology, valued at $120 million in 2010, is expected to exceed $400 million by 2016 (ABI Research reported in eWeek 11/23/11) • Growth triggers • Health-related apps may offer proven techniques in the future; FDA said it will begin requiring regulatory review and software validation (Yahoo! News, 3/21/11) • Development of more consumer-focused apps, with fitness-related apps dominating followed by home monitoring for seniors • Potential cost savings through remote patient monitoring • More peripheral devices (weight scales, blood pressure monitors, and glucose meters) that attach to mobile phones

36. Consumer Health Apps

37. Types of health apps • 4+ categories • Educate • Connect • Track • Remind • “Detect” • Some apps do many of these • Gamification can encompass track and connect • Some apps learn from history and patterns of use • But how many incorporate context, immediacy, affinity, and personalization? • Location-based donut example • Restaurant example

38. Research • “No studies have assessed how well health-related apps change behaviors primarily because academic research tends to lag behind innovation in technology” • LiveScience/Fox News, 3/21/11

39. Limited research to date • Evaluation of iPhone apps for smoking cessation • App’s approach to cessation, its adherence to clinical practice guidelines, and its frequency of downloads • 11.3% of apps strongly followed a given guideline • 4.3% of apps strongly followed the guideline to connect a user with a Quitline • 8.5% of apps made use of intra-treatment social support • Apps that had the lowest adherence scores were also the most downloaded • Measuring downloads only measures downloads! • Abroms

40. Analysis of diabetes apps compared to evidence-based guidelines • Research on both the design and the use of diabetes mHealth applications is scarce • 60 diabetes apps on iTunes for iPhone in July 2009; 260 in February 2011 • Contrasted the prevalence of self-monitoring, education, alerts and reminders, etc. with clinical guideline recommendations for diabetes self-management • “…obvious gaps between the evidence-based recommendations and the functionality used in study interventions or found in online markets. Current results confirm personalized education as an underrepresented feature in diabetes mobile applications” • TaridzoChomutare et al., Norwegian Centre for Integrated Care and Telemedicine, University Hospital of North Norway, Tromsø, Norway

41. Weight Loss Apps: Obesity Trends Among US Adults 1985 and 2010 • Definitions of Obesity • Body Mass Index (BMI) of 30 or higher • BMI • A measure of an adult’s weight in relation to his or her height • Specifically the adult’s weight in kilograms divided by the square of his or her height in meters

42. Obesity Trends* Among U.S. AdultsBRFSS,1990, 2000, 2010 (*BMI 30, or about 30 lbs. overweight for 5’4” person) 2000 1990 2010 No Data <10% 10%–14% 15%–19% 20%–24% 25%–29% ≥30%

43. Obesity and demographics • Obesity affects some groups more than others • Non-Hispanic blacks have the highest rates of obesity (44.1%) compared with Mexican Americans (39.3%), all Hispanics (37.9%) and non-Hispanic whites (32.6%). • Obesity and socioeconomic status • Among non-Hispanic black and Mexican-American men, those with higher incomes are more likely to be obese than those with low income. • Higher income women are less likely to be obese than low-income women. • There is no significant relationship between obesity and education among men. Among women, however, there is a trend—those with college degrees are less likely to be obese compared with less educated women. • Between 1988–1994 and 2007–2008 the prevalence of obesity increased in adults at all income and education levels

44. Healthy Weight Initiative (CDC) • Recommendations designed for patients to promote healthy weight management strategies • Available at: http://www.cdc.gov/healthyweight/index.html • Guidelines that may inform mobile app development • 5 steps to weight loss or preventing weight gain: http://www.cdc.gov/healthyweight/losing_weight/getting_started.html

45. 5 Steps from Healthy Weight Initiative • Make commitment • Write contract that includes goals for accountability • Record important motivators • Define current health status and lifestyle • Assess current weight • Identify current eating and exercise habits • Identify factors that help and hinder a healthy lifestyle • Set goals • Set very specific short and long-term goals related to diet and exercise • Establish rewards to work toward • Access resources for education and support • Identify resources to enable weight loss/healthy diet • Monitor progress • Continuously monitor diet and weight & progress with respect to established goals • Record barriers/obstacles and rewrite goals to address these issues

46. Weight Management App Reviews and Descriptions • Were best-practices guidelines used? • Not clear from app reviews or the descriptions of these apps in app stores that the apps’ developers consulted best-practices guidelines for weight management prior to app design • Few reviews of weight management apps (and other health apps) and few app store descriptions mention evidence-base at all; focus is on features • How customizable? • Some apps allow patients to create a customizable weight management plan but mostly based on age, gender and weight loss goals • Few apps accommodate weight management needs of special populations, such as dietary restrictions (vegan, gluten-free) or health conditions that might influence how a weight management program is planned and implemented

47. Research questions • How do you define app success and learn from experiences? • Is facilitation of social support through mobile devices enough in of itself? • Do existing evidence-based guidelines apply to mobile devices as is? • If not, how can they be “adjusted” or reframed? • Are new techniques needed to evaluate apps? • Not successful for web yet – HONcode, URAC • Are mobile literacy skills needed? • Are mobile health literacy skills needed too? • How can health and public health organizations get a foothold with increasingly commercially-driven approaches?

48. Mobile First • Designing for mobile first instead of retrofitting existing practices into mobile format • Is what is best for people what is most successful in the marketplace? • Evaluation and market research only go so far • My apps were mobile first

49. App challenges

50. My app design • Business travelers have increased rates of poor health and health risk factors, including obesity and high blood pressure • Many apps help locate restaurants based on cost, location, and ethnicity
