Classification: CPC A | IPC A  G

Claim 0:
1. An apparatus for evaluating whether a testee is being deceptive, the apparatus comprising:
an image sensor configured to capture a plurality of sequential images of the testee's pupil;
a processor configured to determine a size of the testee's pupil in the plurality of sequential images;
a circuit that generates an audio output; and
a controller programmed to control the circuit so that the circuit outputs an audio signal corresponding to a set of sentences, wherein the set of sentences includes an initial sentence and at least three first-type sentences, wherein each of the first-type sentences is expected to evoke significant pupil dilation in a testee who is being deceptive and not to evoke significant pupil dilation in a testee who is not being deceptive, and wherein the initial sentence is output prior to the outputting of the first-type sentences,
wherein the controller is further programmed to monitor changes in the determined size of the testee's pupil during the outputting of the first-type sentences and during any responses to the first-type sentences made by the testee,
wherein the controller is further programmed to compare changes in the determined size of the testee's pupil in response to each of the first-type sentences to ascertain whether a pupil-dilation response to each respective one of the first-type sentences is at least 10% larger than a pupil-dilation response to at least two of the other first-type sentences, and
wherein the controller is further programmed to output an indication of deceptiveness or non-deceptiveness for at least one of the first-type sentences based on a result of the ascertaining,
wherein the first-type sentences are all in the same language,
wherein the average volume of each of the portions of the audio signal that corresponds to each of the first-type sentences are all within 10 dB of each other,
wherein each of the first-type sentences has a duration of less than 5 s, and
wherein gaps of at least 3 s are interposed between adjacent sentences within the set of sentences.
