What does Jubo Self Care APP do?

Jubo Self Care APP is a physiological value measurement APP for the general public especially for the elderly

• Record physiological values of devices, including blood pressure, blood oxygen, forehead temperature, blood sugar, and pulse, etc.
• After successfully pairing the measuring device with the Self Care APP, the measured physiological values can be uploaded to the cloud record synchronously.

Why Redesign the Device Pairing Process?

B2B v.s. B2C

Potential Problems

• The current and expected measuring device pairing process and operation methods are very different.General public and older adults tend to be unfamiliar with B2B device pairing process and feel it hard to understand the use of the device itself.
• General public and older adults tend to be unfamiliar with B2B device pairing process and feel it hard to understand the use of the device itself.
• Lack of device descriptions and guidance for pairing steps, resulting in an unsmooth pairing process.

Usability Testing for Original Edition

Tasks

• Connect bluetooth and pair the Forehead Thermometer, the Sphygmomanometer, and the Oximeter with the Jubo Self Care APP.
• Unpair three devices after pairing.

Participants

Purposes

• Understand difficulties users face during the current device pairing process
• Organize what guidance users need while connecting bluetooth and pairing devices
• If the step-by-step instructions for device pairing are to be done, how they should be presented

Rearrange the User Flow and bring up Optimizations

User Flow

After understanding primary difficulties participants have encountered and organizing critical users’ needs, I  rearrange the user flow of device pairing process, in order to fit better with the users’ needs for B2C purposes.

What can be Optimized?

I sorted out general directions to optimize the device pairing process based on the refined user flow.

• It is necessary to clearly guide the user to add a new device.
• Categorize different kinds of devices and enlarge their pictures.
• Different devices require different pairing instructions.
• Modify the unpairing process.

Device Pairing

Step-by-step Instructions Customized for Each Device

• When reaching the last step, users can press the "Pairing" button at the bottom of page to pair the device with APP
• Each step is presented on separate pages
• Three ways to transit pages between steps

• Numeric progress bar
• Left and Right arrows
• Swipe left and right

• Pop-up Dialogues indicate “Pairing Successfully” or “Pairing Unsuccessfully”

Test

Confirm if we Solved Problems of the Original Edition

I conducted second usability test of First Prototype to confirm that redesign edition has solved problems of the original edition and whether new problems arise. Afterward, I organize users’ feedbacks for pairing instructions to optimize it as Second Prototype.

Usability Testing for Redesign Edition

Purpose

• Test if participants can understand instructions of pairing measuring devices, and if the process is smoother.
• Confirm whether the redesign edition can reduce the error rate while pairing and unpairing devices.

Key Finding

• Reduce manual operation and enhance automation for page transitions.
• Reduce misleading and redundant description texts.

Impact on the Company

Device pairing process and user interface of the Second Protoytype are not only used in the Jubo Self Care APP, but also in Jubo's Hi Home care APP, Joygood APP and other related APPs with device measurement and health status recording functions.
In addition, the task completion time and user error rate of the measuring device pairing task were calculated during usability testings. Results show that Second Prototype's task completion time and user error rate were both significantly reduced.
