Ergonomic user interfaces and electronic devices incorporating same
View Patent ↗An electronic device includes a housing that encloses a controller and/or other electronic components, a display viewable through a face of the housing that is configured to display an alphanumeric character list, and an input device adjacent the display that is movable by a user to highlight and select respective alphanumeric characters in a displayed character list. To highlight characters within a displayed character list, the input device is rotatable about an axis that is substantially normal to the display and is slidable within a plane that is substantially orthogonal to the axis. In some embodiments, the input device is rotatable and slidable within a plane that is substantially parallel with a plane defined by the housing face. To select a highlighted character, a user depresses the input device.
1. An electronic device, comprising:
a housing;
a display viewable through a face of the housing, wherein the display comprises a first portion and a second portion, wherein an alphanumeric character list is displayed within the first portion, wherein each alphanumeric character in the alphanumeric character list can be highlighted for selection, and wherein user selected alphanumeric characters from the alphanumeric character list in the first portion are displayed in the second portion; and
an input device that circumferentially surrounds the display and that is movable relative to the display by a user to highlight a respective alphanumeric character in the displayed alphanumeric character list, wherein the input device is rotatable about an axis that is substantially normal to the display and slidable within a plane that is substantially orthogonal to the axis, and wherein the input device is depressible by the user to select a highlighted alphanumeric character.
2. The electronic device of claim 1 , wherein the input device is rotatable and slidable within a plane that is substantially parallel with a plane defined by the housing face.
3. The electronic device of claim 1 , wherein the display and input device are oriented relative to each other such that the input device rotates and slides underneath the display.
4. The electronic device of claim 1 , wherein the display and input device are oriented relative to each other such that the input device rotates and slides above the display.
5. The electronic device of claim 1 , wherein a currently highlighted alphanumeric character is displayed within the second portion of the display in a different format from selected alphanumeric characters displayed within the display second portion.
6. The electronic device of claim 1 , wherein the alphanumeric character list is displayed within the first portion in an arcuate configuration.
7. The electronic device of claim 6 , wherein the alphanumeric character list is displayed within the first portion as a plurality of concentric rows of alphanumeric characters.
8. The electronic device of claim 7 , wherein characters in the displayed alphanumeric character list are highlighted by a cursor, and wherein rotational movement of the input device causes the cursor to move along a row of alphanumeric characters.
9. The electronic device of claim 8 , wherein clockwise rotational movement of the input device causes the cursor to move along a row of alphanumeric characters in a clockwise direction, and wherein counterclockwise rotational movement of the input device causes the cursor to move along a row of alphanumeric characters in a counterclockwise direction.
10. The electronic device of claim 7 , wherein characters in the displayed alphanumeric character list are highlighted by a cursor, and wherein slidable movement of the input device causes the cursor to move from one row to another.
11. The electronic device of claim 1 , wherein the electronic device is a wireless communications device.
12. A user interface for an electronic device, comprising:
a display viewable through a face of a housing of the electronic device, wherein the display comprises a first portion and a second portion, wherein an alphanumeric character list is displayed within the first portion, wherein each alphanumeric character in the alphanumeric character list can be highlighted for selection, and wherein user selected alphanumeric characters from the alphanumeric character list in the first portion are displayed in the second portion; and
an input device circumferentially surrounding the display, wherein the input device is rotatable and slidable relative to the display by a user to highlight a respective alphanumeric character in the displayed alphanumeric character list, and is depressible by the user to select a highlighted alphanumeric, and wherein user selected alphanumeric characters are displayed in the display second portion.
13. The user interface of claim 12 , wherein characters in the displayed alphanumeric character list are highlighted by a cursor, wherein rotational movement of the input device causes the cursor to move along a row of alphanumeric characters in the displayed character list, and wherein slidable movement of the input device causes the cursor to move from one row to another.
