## Abstract

The invention features a headset, and systems including the headset, equipped with electrical sensors. The headset is suitable for use by a child and suitable for use in a gaming system, e.g., to train attention.

## Claims

### Claim 1

A headset comprising:
(i) a front portion comprising a first end, a second end, a sensing bar, and a locator bar, wherein the sensing bar and the locator bar are joined at the first end and the second end of the front portion and comprising a space below the sensing bar and above the locator bar between the first end and the second end, and wherein:
(a) the sensing bar is shaped and configured to contact the forehead of a user wearing the headset and comprises a first electrical sensor positioned to contact the forehead of the user at about position AF3, the first electrical sensor comprising one or more electrodes, and a second electrical sensor positioned to contact the forehead of the user at about position AF4, the second electrical sensor comprising one or more electrodes, and
(b) the locator bar is shaped and configured to rest upon the brow of the user to aid the user in positioning the first electrical sensor at about position AF3 and position the second electrical sensor at about position AF4; and
(ii) a first side portion and a second side portion, the first side portion joined to the first end of the front portion and the second side portion joined to the second end of the front portion, wherein the first side portion, the second side portion, and the front portion, together, are shaped and configured to grip the head of the user, and
wherein the first side portion is rotatably coupled to the first end of the front portion and the second side portion is rotatably coupled to the second end of the front portion to permit the first side portion and the second side portion to fold inward and reduce the size of the headset when not in use.

### Claim 2 (depends on 1)

The headset of claim 1, and wherein at least one of the first side portion and the second side portion further comprise a protrusion, the protrusion comprising a third electrical sensor positioned to contact the user at about position M2 or M1, the third electrical sensor comprising one or more electrodes that contact the skin over the mastoid process of the user.

### Claim 3 (depends on 2)

The headset of claim 2, further comprising a processor equipped with an electronics for selecting and detecting a difference in voltage between (i) AF3 and AF4, and (ii) AF4 and M2 or AF3 and M1.

### Claim 4 (depends on 1)

The headset of claim 1, wherein the first side portion and the second side portion are shaped and positioned to contact the skin over the temporal bone of the user.

### Claim 5 (depends on 4)

The headset of claim 4, wherein the headset is shaped to permit the user to wear the headset and eyeglasses simultaneously.

### Claim 6 (depends on 1)

The headset of claim 1, wherein the maximum distance between the inside edge of the locator bar and the inside edge of the sensing bar is 15±2 mm, 18±2 mm, or 20±2 mm.

### Claim 7 (depends on 1)

The headset of claim 1, wherein the maximum distance between the outside of the locator bar and the outside of the sensing bar is 40±2 mm, 42±2 mm, or 44±2 mm.

### Claim 8 (depends on 1)

The headset of claim 1, wherein each of the first side portion and the second side portion further comprise padding positioned to contact the head of the user.

### Claim 9 (depends on 8)

The headset of claim 8, wherein at least one of the first electrical sensor, the second electrical sensor, and the third electrical sensor is ½ inch or greater in at least one dimension.

### Claim 10 (depends on 8)

The headset of claim 8, wherein at least one of the first electrical sensor, the second electrical sensor, and the third electrical sensor further comprises padding positioned to contact the skin of the user.

### Claim 11 (depends on 1)

The headset of claim 1, wherein at least one of the first electrical sensor, the second electrical sensor, and the third electrical sensor comprise a dry electrode.

### Claim 12 (depends on 1)

The headset of claim 1, wherein at least one of the first electrical sensor, the second electrical sensor, and the third electrical sensor comprise a fabric electrode.

### Claim 13 (depends on 1)

The headset of claim 1, wherein at least one of the first electrical sensor, the second electrical sensor, and the third electrical sensor comprise a silver electrode.

### Claim 14 (depends on 1)

The headset of claim 1, wherein at least one of the first electrical sensor, the second electrical sensor, and the third electrical sensor comprise a silver fabric electrode.

### Claim 15 (depends on 14)

The headset of claim 14, wherein the first electrical sensor and the second electrical sensor comprise a silver fabric electrode.

### Claim 16 (depends on 1)

The headset of claim 1, wherein the sensing bar comprises sockets for directly securing the first electrical sensor and the second electrical sensor, or for receiving a mounting element into which the first electrical sensor and the second electrical sensor are secured.

### Claim 17 (depends on 16)

The headset of claim 16, wherein the mounting element is adjustable to permit control over the spacing between the first electrical sensor and the second electrical sensor.

### Claim 18 (depends on 16)

The headset of claim 16, wherein the first electrical sensor and the second electrical sensor are spaced 7±1 cm apart from center to center.

### Claim 19 (depends on 16)

The headset of claim 16, wherein the first electrical sensor and the second electrical sensor are spaced from 8 cm to 10 cm apart from center to center.

### Claim 20 (depends on 1)

The headset of claim 1, wherein the locator bar has a slight crease at the center of the locator bar.
