Definitions
- WO-A-88/05951 and WO-A-83/02842 describe systems of this type. Although disclosing that other interactive mechanisms may be used, these specifications disclose in particular hand-held sensor devices which are configured to detect the infrared reflectance or absorption of the portion of the printed material located immediately adjacent the head of the sensor device.
- WO 2005/013237-A relates to improvements in interactive printed, material and sensor apparatus for use therewith and discloses sensor devices which
- the sensor unit will not work in an interactive fashion with the product, for example by not reacting to a printed speech bubble (which may or may not have any words printed in it) until the step of applying the sensor to differentially reflective areas has been undertaken. This may involve, for example, simply moving the sensor around randomly on the page.
- interactive information apparatus consisting of printed material and a sensor device adapted to respond to characteristics of printing on the printed material, and wherein the printing on the printed material has intelligible components and non-intelligible components, the latter being sensed by the sensor device, and wherein the sensor device senses differing values of a property of the printed non-intelligible image, and the device includes a processing unit adapted to recognise maxima and minima of the values of the sensed property following the sequential continuous application of the sensor device to a sufficiently large number of differentially (unintelligibly) printed areas of the printed material.
- the detection of the levels and the self-calibration or recalibration thereby achievable in the sensor device is valuable as enabling the device to adapt to the printed material and accordingly to adapt to printed materials produced by different producers and at different times.
- This recalibration can occur irrespective of the sequence in which the . various levels are detected by the sensor device.
- it is particularly preferred to present those levels in a definite fixed sequence because that can enable the sensor device not only to calibrate itself, but, more particularly, to change operational mode from a default mode or some earlier operating mode to a new operating mode. Having read the code, it can also say a word or phrase which corresponds with the graphics.
- Applying the pen to the printed material areas in a desired sequence may be secured by the techniques noted above, for example by some form of pictorially or graphically driven track which has the individual printed areas in the appropriate sequence, by providing all the sequences embedded in the sequential areas which the user applies the pen to in accordance with the instructions on the page or the questions and answers.
- Figure 1 is a representation of a play board and frog used to play a game
- Figure 2 is a diagrammatic illustration of part of a track printed on a game board
- Figure 3 is a graphical illustration of a sensed value response of a sensor passing along the track of Figure 2;
- Figure 5 is a circuit diagram showing a preferred form of circuit for use in a sensor device according to the invention.
- FIG. 1 this shows a frog located to one side of a printed image of five lilypads in a pond.
- the sensor unit is encased in a plastic frog which, when applied to any part of the printed board, gives out an audible signal. Applying the frog to different areas of the board which have different infra-red absorption levels, generates a different signal.
- the frog may be programmed to operate the game, as explained below.
- FIG. 1 there are five lilypads which have been printed using five different tints of infrared absorbent ink, and which are also differentiated by means of colours or numbers so that they look different to the player.
- the player starts the game by placing the frog on the board, actuating a switch which turns the internal electronics on and which causes the frog to say “Jump to any pad”.
- the frog is then lifted off the board and placed back on it by the player, preferably on a lilypad (the background is the same level as one of the lilypads).
- the sensor module in the frog records the level read and confirms the "landing" with positive audio/visual feedback.
- the frog then says "Jump to another pad”.
- the frog is now placed on a new pad, the new landing is confirmed as before and the new level recorded too. However, if the frog jumps to the same pad again, then the level read will be the same, a negative feedback is given followed by "Jump to another pad” again. Eventually, the infrared absorption levels for all five lilypads will have been recorded.
- the sensor module can now assign the levels with predetermined attributes - i.e. the highest level with, say, "yellow”, the next highest with
- the game continues with the frog randomly calling out a colour.
- the frog must now be landed on the specific pad.
- the sensor module compares the latest reading with the remembered level, and feeds back accordingly.
- the game is made challenging by speeding up and by recording the number of hits within a time limit.
- Figure 2 is a typical printed code which can be present on a printed sheet and which consists of a sequence of areas of infrared absorptive ink printed at different densities.
- the infrared absorption detectable by a sensor will accordingly vary depending upon which of the areas the sensor is looking at.
- the technique can, of course, be applied to other properties than infrared absorption.
- the successive areas will give different levels when a sensor is passed across them and, as can be seen, this will actually produce an output as diagrammatically illustrated in Figure 3.
- the sequence in which those maxima and minima occur can in fact represent a code which can be decoded and applied to change the operational mode of the sensor device.
- this generates 16 different codes, each represented by two digits, thus enabling the device to decide which of 16 possible programme modes in which to operate.
- Both the analogue output from the microcontroller 1 and the output from the sensor 4 are conditioned and scaled in passive signal conditioning circuits to allow direct comparison of the two current levels by a comparator 6.
- the digital output of comparator 6 then indicates to the microcontroller's digital input (Din) whether the analogue output is greater than or less than that of the sensor 4.
- microcontroller 1 can determine in software the relative analogue output level of the sensor 4. This then provides a direct digital representation of the sensor's analogue output in much the same way as a traditional successive approximation Analogue-to- Digital Converter (ADC).
- ADC Analogue-to- Digital Converter
- Microprocessor unit 10 also controls whether or not current flows through the emitter diode of an optical infrared emitter/receiver package 13.
- the receiving sensor portion is connected to one input of a comparator 14.
- a comparator 14 Connected to the other input of comparator 14 is a resistance ladder network generally indicated at 15, the ladder network 15 being also connected to outputs of the microprocessor unit 10.
- the circuitry within the microprocessor 10 applies signals to the "rungs" of the resistance ladder 15 which varies the applied voltage to the plus input of comparator 14.
- the voltage applied at that input may be decreased incrementally at very rapid intervals (for example every 100 microseconds) while at the same time the voltage applied to the minus terminal of comparator 14 will depend on the amount of infrared radiation reflected from the surface against which the optical emitter/receiver package 13 is placed.
- the voltage on the minus .input of comparator 14 is always less than the supply voltage, and the output of comparator 14 accordingly stays as a logical 1 until the voltage applied to the positive input of comparator 14 drops below the level applied to the negative input at which point the output drops to logic 0 and accordingly, since the output of comparator 14 is connected to an input of microprocessor 10, the microprocessor then knows precisely what voltage level is applied to the minus input of the comparator, i.e. it has a measure of the infrared reflectance of the surface next to package 13. As package 13 is moved across a sequence of differently reflective areas of printing, the individual levels of absorption can be detected and decoded for use as indicated above.
- the circuit shown in Figure 5 is very simple and inexpensive to produce and accordingly ideal for use in hand-held sensor devices used in conjunction with printed materials for early learning activity books and quiz books.
- the output from transducer 12 may provide an attractive and stimulating level of interactivity between the sensor unit, the printed material and the user.
