We want to work with the Baxter robot intuitively. That’s the reason we decided to use the buttons on the arms of the robot. These buttons are easy to grab because they are on the same level as you are.
The buttons on the arm consist of two push buttons and a scroll button. The scroll button is a clear button because a lot of other devices use this button. The function of the button is therefore naturally. On one of the push buttons is an arrow. It speaks for itself to use it as a ‘back’ button.
We also used the buttons on the wrist (next to the gripper or suction cup) to make waypoints. When you make waypoints, you have to position the arm well. Your hand is then on the wrist, close to the buttons, so it makes sense to use the buttons.
To make it more clear which button you can use, we decided to light up the buttons on the moments you can use them.
On the screen there is no face of Baxter (there is a Baxter face in the original software of Baxter) but an instruction indicating what you have to do. There is main menu where you can choose what you want to do, on the next screens you can refine your choices and run a task with Baxter. By using the screen this way it is easy to see which task you are running and which buttons you can use.
The interface mainly consists of PNG (background) pictures which are loaded in Baxter. The buttons on the interface are also PNG pictures. We decided to use the same layout throughout the interface.
The text bar is on (almost) all of the screens. It indicates the main operation and it is the first thing you read on the screen. When you are assembling the lamp, the text bar disappears after you’ve had the first step. The reason is simple: it gives extra space for instructions and you know what you’re doing when you’re assembling so there is no need for a text bar.
Every screen displays the return button. It indicates that you always can easily leave the page when pushing the button.
On the lamp assembling instruction page you can see how many steps there are. By giving the numbers a different color it points out which step you are in.
The instruction always consists of one or multiple pictures. It gives you more information about the instructions, it indicates the buttons you can use and tells you what the name of an object is.
