E-waste as a global problem

Each day thousands of new products are launched in the market, turning older ones obsolete. The life span of devices is getting shorter and shorter. Many of these devices are rarely used before they are discarded. As a result, more and more unnecessary e-waste is reaching landfills leading to an increasing amount of toxic chemicals in soil, water, and air. This is especially true for household electronic appliances. 

Home appliances ownership in a single household

Lack of care in shared products

Shared products are often troubled by the issue that people don’t take good care of them, which is especially problematic when the hardware is not designed for sharing.

E-magine is a service that enables neighbors to responsibly share seldom used home appliances while incentivizing them to take well care of the devices.

The E-magine service comprises of 3 things - device assistants, an app, and a buyback program:
1. Device assistants will:
- give instructions on how do you use and maintain it;
- react to the way you treat it thus ensuring you take appropriate care;
- remind you of the expiration of your rental period;

Device Assistant
The assistant comes in the form of a robot attached to the plug of the device. The design of the assistant is meant to create an emotional link between the shared appliance and the user. It communicates via sound and slight movements of its head and LED-powered “eyes”.

2. An app powers the sharing model by handling reservations and payments.

3. E-magine ensures that existing resources are being used by buying back home appliances from the households that later on benefit from the service.

Process Overview


We started our research from looking at the topic about electronic waste, in both global and local scale. After doing some secondary research, we locked our eyes into home appliances and how might we design to help replace ownership with sharing service with these products to reduce the waste.
In the spirit of generative research, we decided to embed our research assuptions in some sacrificial prototypes.

Field Research

We chose the student dormitory as our research field as it fitted into the sacrificial scenario we meant to test. In total, we conducted eight in-depth interviews and two intercept interviews.

Coming back from the field, we downloaded our data and made affinity mapping.

The insights were:
1. It is necessary to integrate a mechanism to protect sharing appliances and enable it to work
2. Reminders should not be too “hot” to make people feel bothered
3. The emotional attachment could help incentivize sense of care on the sharing of home appliances

These insights helped us reconfigure our concept and moved onto overall experience prototyping.

Initial UX Video 

We decided to apply the insights we gathered into our design by using a video sketch to frame different touchpoints across the whole experience. Light and monotone sounds were used as notification cues, and basic app screen wireframes were built in the scenario.
