Abstract

Abstract A technique for unobtrusively monitoring a person reading a magazine to determine what page of the magazine is being read. It is necessary to monitor both the magazine as well as the reader's eyes for this purpose. However, test results can be skewed if the reader is placed in an environment to which he is not accustomed. In order to permit the person a great deal of choice as to where to sit and in what sitting position so as to simulate a "natural" environment rather than a test environment, one or more cameras are positioned in the room. In addition at least one mirror is mounted on a wall. The camera may have a direct view of either the reader's eyes or the magazine. Whichever one of these is not directly visible to the camera can be picked up by way of a reflection from the mirror. Various adjustments to the camera are provided so that the reader can be kept in view regardless of where in the room he decides to sit and read.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 196 words
Apparatus for monitoring an individual performing as a test subject who has been placed within a room and is reading a magazine, comprising: camera means for recording an image and including a lens and an image detecting means responsive to light from said lens for producing a signal representative of a recorded image, said camera means having (a) a first portion not visible to the test subject, and (b) a second portion at least partially visible to the test subject; means to direct light from an eye of said individual and from said magazine to said camera means, said light directing means including first means positioned on a surface of said room for directing light it receives from one of said test subject and said magazine toward said second portion of the camera means; and means for adjusting the orientation of a field of view of said camera means, after said individual is seated at any one position selected by the individual out of a plurality of seating positions in said room, to enable monitoring by said camera means of the at least an eye of the individual and said magazine being read by the individual.
Claim 2
Dependent Claim 196 words
Apparatus for monitoring an individual performing as a test subject who has been placed within a room and is reading a magazine, comprising: camera means for recording an image and including a lens and an image detecting means responsive to light from said lens for producing a signal representative of a recorded image, said camera means having (a) a first portion not visible to the test subject, and (b) a second portion at least partially visible to the test subject; means to direct light from an eye of said individual and from said magazine to said camera means, said light directing means including first means positioned on a surface of said room for directing light it receives from one of said test subject and said magazine toward said second portion of the camera means; and means for adjusting the orientation of a field of view of said camera means, after said individual is seated at any one position selected by the individual out of a plurality of seating positions in said room, to enable monitoring by said camera means of the at least an eye of the individual and said magazine being read by the individual.
