In the growth of the Internet of Things, everything is connected. Because of that, the smart home has been a very popular application. However, controlling the smart home is a complex task hidden behind the smart hub application on a smart home or tablet screen fixed on the wall. Because of the inconvenient controlling, we want to create a device to control the ambience of the room, such as lighting, heating, window folds, and music. To ease the control of these repetitive tasks, we propose Smart-ring control to control these properties.


The objective is to study whether a smart-ring control can have an impact on controlling ambience properties of a smart home compared to some state-of-the-art smart hub application currently used to control those properties. In this experiment, we will test the tasks based on lighting, heating, window fold, and music (with changing volume, play/pause, and skip song).


Smart-ring Control

For the Smart-ring control, we designed a prototype where we have 2 rings fit in together, an Inner Ring and an Outer Ring. As shown in the picture below, the outer ring is a cylinder with a window gap in the middle, the inner ring is another cylinder and will be marked with different colors that indicate the active chosen property.

We design the smart-ring so that it will function as follows:

  1. Lighting: Rotation will change the value
  2. Heating: Rotation will change the value
  3. Window fold: Rotation will open/close the window fold
  4. Music: Rotation will change the volume, while one-tap indicate play/pause, and two-taps indicates skip a song.

Smart-hub application

We designed the smart-hub application will functions as follows:



We conducted this experiment in a Wizard-of-Oz type by faking the interaction.

In this experiment, we will conduct the test with 2 prototypes consecutively. One test will be with the smart-ring, follow by a test with the smart-hub application. To balance the test, we will make half of the participants doing the test in that order, and another half doing the test in reverse order (smart-hub first then smart-ring)

For each test, we will create an exact list of task to do. One list for smart-ring, one list for smart-hub application.

There are some survey that we used in this test. After each test with one prototype, we asked the participants to fill in a survey based on System Usability Scale (SUS). At the end of the test, we also have another survey to cover written feedback.


We conduct the experiment in a room where we have

  1. Lighting: will be controlled by a switch on a wall
  2. Heating: will be a monitor screen display fake temperature number
  3. Window fold: will be electronically controlled by a switch located on a wall
  4. Music: will be played on a laptop

Along with the experiment, we recorded the scene with users and their interactions so we can have good analyze afterward.
