Abstract

Disclosed here are a set of methods for entering information into a mobile device which is constrained in terms of its input devices. In particular the methods are applicable to a wrist watch device. Such mobile devices are too small to include a keyboard or even a telephone type keypad. We present a scheme that uses a roller wheel combined with a touch sensitive screen to enable users to enter alphabets, numbers and special characters easily. We also describe how users can backspace and correct mistakes during the text input process.

This text was extracted from a PDF file.
At least one non-text object (such as an image or picture) has been suppressed.
This is the abbreviated version, containing approximately 56% of the total text.

Text input on a smart watch with a roller wheel and touch screen

The user interface for the wrist watch consists of a touch sensitive screen and a roller wheel. Though the resolution of the touch screen is quite fine grain, since the preferred mode of interaction is for the user to tap on the touch screen with a finger instead of a stylus we limit the relevant touch zones to four quadrants. The roller wheel can be rolled in either clockwise or counter clockwise directions and clicked in to select. In other words the roller wheel can be used as a one-dimensional mouse.

For text input using these input devices we present the 26 letters of the alphabet as two concentric circles as shown in the following picture.

The user can roll the wheel to move the highlight that is on the letter M to different letters and push the wheel in to select the different letters to make up the input sequence. If the user makes a mistake, the user can touch on the bottom left quadrant of the touch screen to back space over the incorrect letter. The sequence of letters that is built up will be shown in the center of the screen

The letter A-Z are displayed in concentric circles with a flashing cursor in the center. The user can roll the wheel to the desired letter and click the wheel to enter the letter. Each wheel click copies the selected letter to the string that is built in the center as shown in the following figures (entering the name JOHN)

After the name has been entered the user can tap on the touchscreen top right or bottom right to go to other screens that have numbers/special characters or lower case characters etc. An example is shown below. Here the screen consists of the characters 0-9 and the special characters ( ) - and space.

If during the entry process the user makes a mistake, the user can tap the lower left corner to back up one character. Repeated taps can be used to erase multiple characters.

To complete the entry, we can either use the entry of two consecutive spaces to signify completion or use a special completion character on a menu list. Alternatively a touch screen tap in the center can also be used to signify completion.
