Overview

This idea came from the Manatree people, ment as a solution for customers to measure their usage of energy per electronic item in their household. It can be plugged into the Toon, the smart meter.

My role

Customer Research. Customer development. Targeted at Eneco.

Duration

As long as there were candidates to do the project


The Challenge- The Approach - The Discovery - The Framework - The Refinement

The challenge

Be more aware of energy usage

Energy Android application displays the home appliances’ energy consumption information. People can monitor their energy consumption at home and possibly be more aware of the energy usage.

The UI structure of Eidos app is as follow:


The approach

UX tests

In this roud of user test we aimed to validate the usability pespective of Eidos app.

We made the following hypotheses:

 

  • To delete a device from the overview list, long press + context menu is more efficient than the delete function from the overflow menu.
  • The schedule chart can be easily found.
  • People can understand the consumption chart and schedule chart.
  • Regarding comparison feature, people would like to compare the energy consumption between (1) the current week and the most efficient week, (2) the current week and the lowest efficient week, and (3) the current week and the same week of last month and last year.

8 paritipants attended the user tests, including 6 males and 2 females. They all have experience of using Android phone. 2 participants out of 8 have the experience of using energy consumption monitoring device at home.

Each user test session is less than 30 minutes. One moderator and two observors /note takers performed the user test.

Upcoming features

Showing total energy consumption of the house

Participants would like to see the total energy consumption information of the house/total devices. They also want to see the average energy consumption per device.

Besides, participants would like to compare the total house energy consumption.

Proposal:

The application should display the overall energy consumption of all the devices. Besides, people can compare the overall energy consumption between the current timeframe and the previous timeframe.

 

Showing device’s “On/Off” status

Participants would like to see the device “On/Off” status to monitoring the irregular situation of devices. One participant commented that with “On/Off” information she could be notified when the washing machine finished. So she does not need to go to the washing machine to check frequently.

Proposal:

Add “on/off” status indication to the devices overview list. As an extra feature, add an option that the user can select to be notified if the state of a device changes.

 

Other ideas

During user tests, we received the following questions. They can be new features for the future.

 

  • A person has more than one residences. If he would like to monitor all of them within the same app, how will information be displayed?
  • The app shows monthly energy consumption. When to when is a month? (the app should be based on the billing period, as well as provide the option to user to customize a month. ). And customize the price they pay for energy. Besides, peak hour price and time should be considered.
  • Participants would like to compare their energy consumption with other users who have the similar situation (family size, house size and so on). They want to know whether they are doing well or bad.
  • Remian the old device information. People can compare the old device with the new device.

Conclusion

Besides of the above findings, we also validated the hypothesese through the user test.

  • To delete a device from the overview list, long press + context menu is more efficient than the delete function from the overflow menu.
  • -> it is right. Most pariticpants deleted a device through long press + context menu.
  • The schedule chart can be easily found.
  • -> participants all found the schedule chart when exploring the app. However, they could not recognize the information displayed in the schedule chart.
  • People can understand the consumption chart and schedule chart.
  • -> They understood the consumption chart, however they could not get exact information from it. Regarding the schedule chart, please see the previous point.
  • Regarding comparison feature, people would like to compare the energy consumption between (1) the current week and the most efficient week, (2) the current week and the lowest efficient week, and (3) the current week and the same week of last month and last year.
  • -> participants are more interested in the comparison of the longer time interval, i.e. monthly or yearly comparison.
