## Abstract

A stenographic device includes a display, a memory, keys of a stenographic keyboard, each key having a resting position where the key is un-actuated, a depressed position where the key is actuated to register a key stroke, and a range of depression positions therebetween, and a processor communicatively coupled to the display, memory, and the keys. The processor causes the display to graphically show a respective depression indicator of a current one of the depression positions for each of the keys, stores in the memory a respective key-press registration point for each of the keys, the registration point being a depression position located within the range of depression positions and indicating when the respective key is in the actuated state, and causes the display to graphically show a respective registration indicator corresponding to the stored registration point for each of the keys.

## Claims

### Claim 1

A stenographic device comprising:
a plurality of keys making up a standard stenographic keyboard, each key having a resting position in which the key is in an un-actuated state, a depressed position in which the key is in an actuated state where a key stroke is registered, and a range of depression positions between the resting position and the depressed position;
a display;
a memory; and
a processor communicatively coupled to the display, to the memory, and to the plurality of keys the processor being operable
to store in the memory a respective key-press registration point for each of the keys, the registration point being a depression position located within the range of depression positions and indicating when the respective key is in the actuated state.

### Claim 2 (depends on 1)

The stenographic device according to claim 1, wherein:
the processor is operable to cause the display to graphically show a respective depression indicator of a current one of the depression positions for each of the keys;
the depression indicator is of a first color on the display when a key of the plurality of keys is at a depression position located between the resting position and the depression position corresponding to the registration point; and
the depression indicator is of a second color on the display different from the first color when the key is at a depression position located between the depression position corresponding to the registration point and the depressed position.

### Claim 3 (depends on 2)

The stenographic device according to claim 2, wherein the first color is red, the second color is green, and a registration indicator for the key is blue.

### Claim 4 (depends on 1)

The stenographic device according to claim 1, further comprising a key sensitivity adjuster operable to set the registration point to a new value.

### Claim 5 (depends on 1)

The stenographic device according to claim 1, further comprising a speaker communicatively coupled to the processor, the processor being operable to communicate to the speaker and the speaker being operable to broadcast at least one audio signal for at least one of the keys to indicate a current depressed position of the at least one key.

### Claim 6 (depends on 1)

The stenographic device according to claim 1, wherein the processor is operable to cause the display to graphically show a respective registration indicator corresponding to the stored registration point for each of the keys.
