## Abstract

The invention relates to a method of testing an infant, comprising the following steps: displaying a target on a screen; detecting contact made by the infant with the screen inside and/or outside the target; calculating a success parameter on the basis of the contact detected; and recording the calculated success parameter in a memory.

## Claims

### Claim 1

A method to test an infant aged from 0 to 6 months comprising a test phase (200, 300) comprising steps of:
displaying a target (17, 18, 21) on a computer screen (14),
detecting points of contact and instants of contact of the infant with the computer screen (14) inside and/or outside the target (17, 18, 21) using a processing module (11), wherein the points of contact and the instants of contact are recorded in a chronological order,
after a contact between the infant and the computer screen (14) inside the target (21) is detected, shifting the target (21) on the computer screen from a position (Pi) to a following position (Pi+1) according to a predetermined sequence of positions,
calculating, using the processing module (11), a success parameter as a function of the points of contact and/or the instants of contact detected, and
recording the calculated success parameter in a computer memory (12),
wherein the calculated success parameter comprises at least one of:
a distance between a point of contact of the infant with the computer screen (14) and a position of the target (17, 18, 21) displayed on the computer screen (14);
a duration between two successive instants of contact of the infant with the computer screen (14) inside and/or outside the target (17, 18, 21);
a success rate equal to the ratio between a number of contacts inside the target (17, 18, 21) and a number of contacts outside the target (17, 18, 21); and
a success rate equal to the ratio between a number of contacts inside the target (17, 18, 21) and a total duration of the test.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the predetermined sequence of positions comprises a start position (P1), the method comprising a step of:
if no contact is detected during a predetermined duration, displaying the target (21) in the start position (P1).

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein, in one of the predetermined sequence of positions (Pj-Pk) of the sequence, the display of the target (21) is omitted.

### Claim 4 (depends on 1)

The method as claimed in claim 1, comprising a step of:
displaying a mask (24) in a zone of the computer screen (14),
wherein, in one of the positions (Pj-Pk) of the sequence, the target (21) is hidden by the mask (24).

### Claim 5 (depends on 4)

The method as claimed in claim 4, wherein the mask (24) is displayed before or after the target (21) is displayed in the position (Pj-Pk) of the sequence in which the target (21) is hidden by the mask (24).

### Claim 6 (depends on 1)

The method as claimed in claim 1, wherein the target (21) has a dimension between 0.5 and 5 centimetres.

### Claim 7 (depends on 1)

The method as claimed in claim 1, comprising a step of:
displaying the calculated success parameter on the computer screen (14).

### Claim 8 (depends on 1)

The method as claimed in claim 1, comprising another test phase (100) during which an active target (17) and an inactive target (18) are displayed on the computer screen (14), the other test phase (100) comprising a step of:
after a contact between the infant and the computer screen (14) inside the active target (17) is detected, triggering visual and/or aural stimulation.

### Claim 9 (depends on 1)

The method as claimed in claim 1, comprising another test phase (100) during which a first active target (17) and a second active target (18) are displayed on the computer screen (14), the other test phase (100) comprising steps of:
after a contact between the infant and the computer screen (14) inside the first active target (17) is detected, triggering a first visual and/or aural stimulation, and
after a contact between the infant and the computer screen (14) inside the second active target (18) is detected, triggering a second visual and/or aural stimulation, different to the first visual and/or aural stimulation.

### Claim 10 (depends on 1)

A test device (10) of an infant comprising a touch screen (14) and a processing module (11) configured to execute the steps of the method as claimed in claim 1.

### Claim 11 (depends on 1)

A non-transitory storage medium readable by computer equipment on which a computer program is recorded, comprising code instructions for execution of a method as claimed in claim 1.
