Still working on a video player solution. Until then, check out the video on YouTube.

Subject Stats & Familiarity

40 year-old 5’ 11“ male. 7.5“ long hand (average). Writes with left, better fine motor control with right (credits living in a predominately right-handed world).

Consultant. Scrum Master and Agile Coach for organizations and productivity coach for individuals.

Feels familiar with Apple and Apple products since at least 2005.

He has owned:

  • 2009, 2013, 2017, and 2019 15“ MacBook Pro
  • 2006 and 2011 Mac Mini
  • iPhone 4, 5, 5s, and 8
  • 3rd Generation Apple Watch
  • 2012 and 2015 Apple TV
  • AirPods 1 and 2

He is also part of the Apple Developer Program, having released an app to the App Store in 2011, which was recently taken down due to lack of updates (states users - including self - were neither reporting defects nor asking for new features and it was under 3MB, not sure what else to do).

8fold Media, the publishing division of the small business he owns has also published their first book, which is available on Apple Books. He is also considering registering with his content with Apple News and creating a podcast.

Day in the Life

Wakes up. Checks social media. Potentially prepares video content for later viewing.

Takes device into bathroom. Mainly for access to voice assistant, Siri. Sometimes listens to instructional content as well.

Gets dressed. Transfers contents of pockets to pants. Wallet in the back-right pocket. Cellphone in front right pocket. Cigarette pack, lighter, keys, cash, and AirPods 2 case in front-left pocket. Places one AirPod in ear, which will then be rotated througout the day, as needed.

Walks to work (no car). Usually carrying 13lb messenger bag to keep both hands relatively free. Left is usually occupied by water bottle, cigarette, snack from a convenience store. Right hand is usually free to grabe phone, if necessary (skipping ads, pausing audiobook to go to text-based version of same book and make an annotation, and so on).

At work often facilitates meetings and uses Hey, Siri to set timers for activities. Minimal phone calls. Few text messages. Most notifications has been turned off or disabled. (Subject doesn’t like devices making noise or causing distractions, or worse, interruptions.)

Subject claims this covers 90% of usage.

Pain Points

Primary pain point is related to device size. Subject would like to be able to control the device in its entirety with one hand.


Reach-ability accessibility feature has been enabled: Subject doesn’t use it very often as he says he usually starts middle or up, then needs to go down, tap twice, then go back up.

AssistiveTouch accessbility feature had been enabled: Subject doesn’t use it very often as it still takes more time than the next workaound. Further, it can be somewhat distracting or just in the way of items that are in the hotspot area of the device for him (the edge of the phone closest to his extended thumb). However, he hasn’t disabled it as he’s only been trying to modify his before for six months.

One finger raise (bring device to thumb instead of thumb to device): For this the subject uses his index finger to press the device against his thumb instead of moving his thumb to touch the device. Subject is concerned that the device gets placed in a “precarious” (compromised) position as the middle, ring, and pinky fingers are removed from holding the device.

Two-handed grip: Subject prefers one-handed use and can do many things “relatively easily.” However, for those moments where more interaction with the device is required, the subject will engage left hand and interlace the fingers giving him full coverage of the device with left-hand and potential to use both thumbs for data input with the keyboard.
