1 Wearables Mobile Application Development

2 It was news to me In preparing this lecture, I did research into wearable computing in general Turns out, there s been a conference on wearable computing since 1997! Here are some highlights! 2

3 It was news to me Sensor-Embedded Teeth for Oral Activity Recognition 3

4 It was news to me Canine Reachability of Snout-based Wearable Inputs 4

5 Wearable is a bit broad The term wearable computing is really built around any device that is attached or worn in some way So, the possibilities here are vast Mobile sensors User interfaces NFC communication Etc. 5

6 This is more what I was thinking 6

7 This is more what I was thinking 7

8 Watches 8

9 Can t I have both? 9

10 How is this mobile? Obvious reason watches are mobile Other important reasons Modern smart watches are a companion device to smart phones Most can work independently, but their real power comes when connected Both Apple and Google have release versions of their mobile OS for watches and there are direct connectivity APIs that you can use 10

11 Pebble Arguably, watches really took off with Pebble 018/pebble-e-paper-watch-for-iphone-andandroid Pebble has 2 of the 3 most backed Kickstarters EVER There is definitely a market out there! e-ink display = high battery life Uses: notifications, running, controlling music 11

12 They re still going! Pebble 018/pebble-time-awesome-smartwatch-nocompromises?ref=most_funded 12

13 How much tech do you need? Desktop stand-alone computing, highperformance Laptop work/school, portable, highperformance Tablet entertainment, portable, moderate performance (different sizes) Mobile digital assistant, very portable, moderate performance (also in different sizes) 13

14 I m a bit embarrassed MacBook Pro: primary machine, work/personal Windows 10 desktop: mainly gaming ipad Air: watching Netflix, Hearthstone ipad Mini 2: watching Twitch, YouTube Hearthstone iphone 6: primary mobile device Not to mention lots of older stuff... Do I really need a watch? 14

15 One Week w/ the Apple Watch Got an Apple Watch (for this class research in spring 2016) Thoughts wearing Apple Watch Sport after one week Would I notice any useful situations? What would I notice about using it? 15

16 One Week w/ the Apple Watch Positives: I forgot how nice it was to check the time without pulling out my phone Vibration notification Siri integration HealthKit integration Apple Pay integration iphone partnership app Glances and Complications 16

17 One Week w/ the Apple Watch Negatives: Distractions Menu system Some things can t be customized Recognition over recall not always there My wife keeps telling me I got the woman s version (the smaller and larger are not deliniated as such by Apple) 17

18 More time w/ the Apple Watch Changing songs in the car while GPS map is up is really nice Primary use cases: Checking the time / temp / activity log Texting Running watch features Buying things with Apple Pay Hard to wear with a dress shirt 18

19 Apple Watch vs. Android Wear Apple Watch Very limited usage without iphone Apps are connected extensions of installed iphone apps Apps are made up of the app extension itself, a glance, a complication (glace and complication are optional) Glance is a card that you add to a quick menu Complication is an addition to the watch face 19

20 Apple Watch vs. Android Wear Android Wear Like Android phones, built by various companies Multiple sizes, form factors, and capabilities Can stand alone from phone much more than Apple Watch (for example, some have their own Wi-Fi Uses the same Material card UI metaphor that the rest of Android uses 20

21 What would we build? Native App (Android only) Could be like many other apps you build, but with much smaller screen Extension Apps (Android and ios) Notifications (reminder, to-do, messages, etc.) Control (change station, volume, etc.) Sensors (health, running, etc.) Information (weather, traffic, etc.) 21

22 Some Examples

23 Example: Grocery List 23

24 Example: Grocery List 24

25 Developer Questions Q1: Do I need a phone extension (or version)? One thing I noticed from using the Apple Watch is a LOT of apps have an extension just because 25

26 Developer Questions Good Apple Watch Apps Buy Me a Pie (grocery list) Seven Minute Workout (works with sensors) Due (reminders) Google Maps (directions on your wrist!) Pandora (control your music) Shazaam (what is that song?) Weather Underground (quick weather forcast) 26

27 Developer Questions Odd Apple Watch Apps Chipotle? Consumer Reports? FlightRadar? Fandango? AAA? Amazon? 27

28 Developer Questions Q2: Would a watch app add anything to my full app? Is there timely information the app needs to provide? Can it be shown in a very small format? Are there simple controls to the app that could be added to a watch? Q3: Do I have the resources/time to do this? Currently limited market impact 28

29 Developer Questions Q4: What type of interaction do you want the user to have? Apple Watch: Glance? Complication? Android Wear: Notifications? 29

30 Q5: Is it even usable? Developer Questions Wireframe time! User testing a must 30

31 Exciting Opportunities! More sensors and more tracking! 31

32 Exciting Opportunities! 32

33 Exciting Opportunities! Silent and seamless notifications! It is rude to pull out your phone during a conversation or interview to check a message you just got Glancing at your watch, however, is a bit more socially acceptable (not saying this is always a good idea for the situation, but it s arguably better than the phone) 33

34 Exciting Opportunities! More hands-free usage! NFC pay solutions NFC locking solutions in the future? Quick lists / short information bursts Parallel example: Smart Entry on cars 34

35 Is it for everyone? No, probably not This is a value add for many apps Probably not make or break but can be a plus For me, it does feel a bit like overkill... But I m going to keep wearing it... The health data is nice and the reminders help Using Siri without pulling out the phone is nice... And I like shiny things made by Apple... 35
