Inspired by eco-feedback systems such as the Power-Aware Cord [1] or PowerSocket [2], Wattom is a smart plug that is both an energy-aware display and an interactive device. Using Wattom, information can be obtained:

- Via moving lights of different colors, speeds, and directions;
- Via background colors;
- Via a smartwatch display.

Users can interact with Wattom by matching the animation of any moving light with their hands; this matching motion is tracked via the users' smartwatches. In previous studies, we designed these mid-gestures [3] so that the user can directly and immediately interact with the source of the information without being hindered by additional proxy-devices (e.g., a mobile phone).

Recall: the goal of this survey is to collect your ideas on what eco-feedback information to display on an interactive smart plug (and to what purpose) via three speculative scenarios related to energy efficiency in future smart homes or office spaces. As such, each survey page will ask you to provide one eco-feedback idea consisting of a textual description and rationale for this eco-feedback information (what / how / where / when):

1. [WHAT] Example from the Wattom video (Application #1): "I want to know which percentage of the energy I am about to consume was generated from renewable sources. That way I can decide to postpone my activity to a more sustainable period of time."

2. [HOW] Example from the Wattom video (Application #1): "I would like the Wattom background colors to reflect this percentage: closer to 0% displayed in red; closer to 50% displayed in green; and somewhere in between displayed in yellow. I would also want to Wattom's moving light to make it harder to interact with the appliance connected: maybe faster movements when closer to 0%".

Recall: how would the eco-feedback information above map to Wattom's output capabilities: the moving lights of different colors, speeds, and directions; the background colors; and/or the smartwatch display.

3. [WHERE] The location where this information would be most useful in your opinion (e.g., home, work). Further, what appliance/device does this information relates to (if any).

4. [WHEN] When should this information be displayed.
