Input apparatus for a handheld electronic device and method of enabling input employing the same
View Patent ↗An improved input apparatus and method of enabling input improve handheld electronic devices having a housing and a processor apparatus disposed on the housing. The processor apparatus comprises a processor and a memory. The input apparatus includes an input assembly with an input device for providing input to the processor, a plurality of input members, and at least a first actuating element movable between a first position and a second position. In the second position, the actuating element actuates the input device. Each input member of the portion of input members is movable among an unactuated position and an actuated position. Each of a plurality of input members of the portion of input members, in the actuated position, is engageable with the actuating element to move it toward the second position. The input apparatus enables close arrangement of the input members to provide, for example, a compact keyboard layout.
1. A handheld electronic device, comprising:
a processor; and
an input apparatus having:
a plurality of input members, each of the plurality of input members having an actuating portion and each being configured to move independently;
a single user feedback device associated with the plurality of input members;
a single actuating element having a plurality of reaction portions, each of the plurality of reaction portions being associated with an actuating portion of one of the plurality of input members, the single actuating element configured such that actuating one of the plurality of input members provides a first input to the processor, and causes its respective actuating portion to engage its associated reaction portion thereby moving the single actuating element to engage the input device, and shifting the other of the plurality of reaction portions to an unengageable position with respect to the actuating portions of the other of the plurality of input members;
and a communication element including a plurality of electrical contacts arranged thereon; and wherein actuation of the one of the plurality of input members completes an electrical circuit to provide the first input and actuation of another of the plurality of input members provides a second input to the processor; and wherein when the single user feedback device is engaged due to actuation of the one of the plurality of input members, the second input is ignored by the processor.
2. The handheld electronic device of claim 1 wherein the actuating portion is a cam portion.
3. The handheld electronic device of claim 2 wherein the single actuating element includes a number of apertures, each aperture having an end defining one of the plurality of reaction portions.
4. The handheld electronic device of claim 1 wherein the single actuating element is selected from the group consisting of a push rod, a plate member, and a combination of at least one push rod and at least one plate member.
5. The handheld electronic device of claim 1 wherein the single actuating element is configured to translate upon actuation of one of the plurality of input members.
6. The handheld electronic device of claim 1 wherein the single actuating element is configured to rotate upon actuation of one of the plurality of input members.
7. The handheld electronic device of claim 1 wherein the single user feedback device is a tactile feedback device.
8. The handheld electronic device of claim 1 wherein the one of the plurality of input members includes a conductor at one end, the conductor being configured to electrically engage a pair of the plurality of electrical contacts to complete the circuit.
9. The handheld electronic device of claim 1 further comprising:
a second plurality of input members, each of the second plurality of input members having an actuating portion and each being configured to move independently;
a second single user feedback device associated with the second plurality of input members; and
a second single actuating element having a plurality of reaction portions, each of the plurality of reaction portions being associated with an actuating portion of one of the second plurality of input members, the second single actuating element configured such that actuating one of the second plurality of input members causes its respective actuating portion to engage its associated reaction portion thereby moving the second single actuating element to engage the input device, and shifting the other of the plurality of reaction portions to an unengageable position with respect to the actuating portions of the other of the plurality of input members.
10. The handheld electronic device of claim 9 wherein the plurality of input members are disposed in a first region of the input apparatus, and the second plurality of input members is disposed in a second region of the input apparatus spaced from the first region.
11. An input apparatus for a handheld electronic device, the input apparatus comprising:
a plurality of input members, each of the plurality of input members having an actuating portion and each being configured to move independently;
a single user feedback device associated with the plurality of input members;
a single actuating element having a plurality of reaction portions, each of the plurality of reaction portions being associated with an actuating portion of one of the plurality of input members, the single actuating element configured such that actuating one of the plurality of input members causes its respective actuating portion to engage its associated reaction portion thereby moving the single actuating element to engage the input device, and shifting the other of the plurality of reaction portions to an unengageable position with respect to the actuating portions of the other of the plurality of input members; and
a communications element including a plurality of electrical contacts arranged thereon; and wherein actuation of the one of the plurality of input members completes an electrical circuit by contacting at least one of the plurality of electrical contacts to provide an input to a processor in the handheld device and actuation of another of the plurality of input members provides a second input to the processor; and wherein when the single user feedback device is engaged due to actuation of the one of the plurality of input members, the second input is ignored by the processor.
12. The input apparatus of claim 11 wherein the actuating portion is a cam portion.
13. The input apparatus of claim 12 wherein the single actuating element includes a number of apertures, each aperture having an end defining one of the plurality of reaction portions.
14. The input apparatus of claim 11 wherein the single actuating element is selected from the group consisting of a push rod, a plate member, and a combination of at least one push rod and at least one plate member.
15. The input apparatus of claim 11 wherein the single actuating element is configured to translate upon actuation of one of the plurality of input members.
16. The input apparatus of claim 11 wherein the single actuating element is configured to rotate upon actuation of one of the plurality of input members.
17. The input apparatus of claim 11 wherein the single user feedback device is a tactile feedback device.
