More specifically, the presently disclosed technology relates to a communication device, such as a cellular phone, that allows a user having limited physical dexterity to more effectively and accurately provide input into the device. The presently disclosed technology teaches a communication device with at least a touchscreen input device and a physical keyboard, wherein the control capabilities of the touchscreen input device may be disabled and/or re-enabled. The disabling and/or re-enabling may occur based on an input received into an input device or may occur automatically based on the contextual usage of the communication device. Still further, the electronic device may include a touchpad that may comprise a non-slip surface and may be sized and/or shaped such that users with limited physical dexterity may more efficiently navigate the interface of the communication device using the touchpad. ## Claims ### Claim 1 An improved electronic device for users having limited physical dexterity comprising: a body comprising a front facing side; a plurality of input devices physically accessible from the front facing side, wherein the plurality of input devices comprises at least a touchscreen display and a physical keyboard; a processor internal to the body and coupled to the plurality of input devices; memory internal to the body and coupled to the processor, the memory containing programs to cause the processor to operate the electronic device, the programs including a program to cause the processor to interact with the plurality of input devices; a transceiver coupled to the processor and adapted to communicate with a base station; and a sensor for detecting the presence of an obstruction in front of the touch screen display, wherein the processor, when executing a program stored in the memory in the absence of a detected obstruction to the touchscreen by the sensor, disables the control capabilities of the touchscreen display based on a first input received by at least one of the plurality of input devices and re-enables the touchscreen display based on a second input received by at least one of the plurality of input devices. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein at least one of the plurality of input devices is a touchpad comprising a non-slip surface. ### Claim 3 (depends on 2) The electronic device of claim 2, wherein the touchpad has a first edge adjacent a first vertical edge of the front facing side and a second edge adjacent a second vertical edge of the front facing side. ### Claim 4 (depends on 3) The electronic device of claim 3, wherein the touchpad has a hexagonal shape. ### Claim 5 (depends on 2) The electronic device of claim 2, wherein the touchpad is detachable. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein at least one of the plurality of input devices is a touchpad comprising a fingerprint identity sensor. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the first input and second input are different. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the first input and second input are programmable by a user using a graphical user interface of the electronic device. ### Claim 9 (depends on 1) The electronic device of claim 1, wherein at least one of the plurality of input devices is a microphone and at least one of the first or second inputs is an audio input. ### Claim 10 An improved electronic device for users having limited physical dexterity comprising: a body comprising a front facing side; a plurality of input devices physically accessible from the front facing side, wherein the plurality of input devices comprises at least a touchscreen display and a physical keyboard; a processor internal to the body and coupled to the plurality of input devices; memory internal to the body and coupled to the processor, the memory containing programs to cause the processor to operate the electronic device, the programs including a program to cause the processor to interact with the plurality of input devices; a transceiver coupled to the processor and adapted to communicate with a base station; and a sensor for detecting the presence of an obstruction in front of the touch screen display, wherein the processor, when executing a program in the memory in the absence of a detected obstruction to the touchscreen by the sensor, automatically disables the control capabilities of the touchscreen display based on the contextual usage of the device by a user of the touchscreen. ### Claim 11 (depends on 10) The electronic device of claim 10, wherein at least one of the plurality of input devices is a touchpad comprising a non-slip surface. ### Claim 12 (depends on 11) The electronic device of claim 11, wherein the touchpad has a first edge adjacent a first vertical edge of the front facing side and a second edge adjacent a second vertical edge of the front facing side. ### Claim 13 (depends on 11) The electronic device of claim 11, wherein the touchpad is detachable. ### Claim 14 (depends on 10) The electronic device of claim 10, wherein the processor automatically disables the control capabilities of the touchscreen display. ### Claim 15 (depends on 10) The electronic device of claim 10, wherein the processor automatically re-enables the control capabilities of the touchscreen display. ### Claim 16 (depends on 10) The electronic device of claim 10, wherein the processor automatically disables or re-enables the control capabilities of the touchscreen display based on which application is being used by a user. ### Claim 17 An improved electronic device for users having limited physical dexterity comprising: a plurality of input devices, wherein the plurality of input devices comprises at least a touchscreen display and a physical keyboard; a processor; memory containing programs to cause the processor to operate the electronic device, the programs including a program to cause the processor to interact with the plurality of input devices; a transceiver; a system interconnect coupled to the plurality of input devices, processor, memory, and transceiver; and a sensor for detecting the presence of an obstruction in front of the touch screen display, wherein the processor, when executing a program in the memory in the absence of a detected obstruction to the touchscreen by the sensor, disables the control capabilities of the touchscreen display based on a user input or automatically based on the contextual usage of the device by a user of the touch screen. ### Claim 18 (depends on 17) The electronic device of claim 17, wherein at least one of the plurality of input devices is a touchpad comprising a non-slip surface. ### Claim 19 (depends on 18) The electronic device of claim 18, wherein the touchpad is detachable. ### Claim 20 (depends on 17) The electronic device of claim 17, wherein the processor further re-enables the control capabilities of the touchscreen display based on a user input or automatically based on contextual usage information of the device.
