DEVICE TRACKER

Problem Statement:

Customers who own Zebra devices in their work environments have voiced a problem where they are having trouble keeping track of “lost devices” or “misplaced devices”.

 

Store associates/device users can easily misplace a device in a large retail environment, can forget to return the device to it’s designated location, etc. This is actually a big expense for our customers as our devices are critical to their operational workflow.

 

Zebra would like to create a tool that enables customers to easily designate a device as lost, find devices using an application of some sort, possibly use other devices to fetch the lost device, etc. 

Brainstorm 

I was given a brief by the product owner, after reviewing it I mapped out all my thoughts and possible features. Then I pulled in some other ID team members and built on what I already had. I mapped out the user journey for the mobile and the web app.

Case studies

I looked at existing products and mapped out my journey. Making note of what worked well, how I was interacting with the product and of the variety of user interfaces. 

Prototyping

I created the first prototype combining feature I felt worked well In existing products in the market.

Limitations

I presented the idea back to the team, despite good feedback it became apparent that given the time till first release and technical restrictions the map view was not a viable option.

 

I would need to move forward using sound and distance alone.  

First release

The first release featured a pulsing radar style tracker that indicate distance. 

The colour changed from green to red if the user started moving further away from the target. It showed the distance in feet and contained the play sound feature. 

Use case - happy path

  1. The user chooses device 

  2. user hits play sound button

  3. user walks towards sound using the distance feature/ colour for positive reassurance 

  4. User repeats steps 2&3 until they get to device 

  5. List device as found

Second release

Feedback from first release informed us that the accuracy of the technology used to show distance wasn't good enough. The decision was made to put that feature was put on hold.

 

The second release featured a pulsing radar style tracker that indicate distance (no listed distance)

The colour changed from red, to orange, to green to show the user started moving further away from the target or closer. It contained the play sound feature. 

Use case - happy path

  1. The user chooses device 

  2. user hits play sound button

  3. user walks towards sound using the colour for positive reassurance 

  4. User repeats steps 2&3 until they get to device 

  5. List device as found

Third  release

After some further developments where made by the team the distance tracker was put back on the table. 

The pending release features a slide that indicate distance (far-close) as well as distance. This also includes the introduction of the signal icon an colour. 

Use case - happy path

  1. The user chooses device 

  2. user hits play sound button

  3. user walks towards sound using the distance and slider for positive reassurance 

  4. User repeats steps 2&3 until they get to device 

  5. List device as found
