  • One example device is a child's drawing pad. In this case the child is provided with a variety of styli 931 fashioned as magic markers or crayons. Each provided stylus 931 draws a unique color when used on screen 800. The color

  • FIG. 2 shows electronic device 826 used with a second stylus 931 having a wider head than stylus 931 of FIG. 1. Accordingly, the drawn line 932 in FIG. 2 is wider than that of FIG. 1. Drawn line 932 in FIG. 2 is green, indicated by the dash-dot line pattern. Additional attributes of drawn lines may also be included in the RFID tag, such as a pattern, e.g., solid, dashed or dotted.
  • the width of line 932 is provided together with the line color on tag 780.
  • the line width is determined by the detected touch area.
  • High resolution touch sensors such as those described in U.S. Application No. 13/424,592 entitled LIGHT-BASED FINGER GESTURE USER INTERFACE, enable determining the size of a covered area during a touch.
  • the line width corresponds to this area.
  • the different detected touch areas are shown in the graphs depicted in FIGS. 1 and 2.
  • the graphs show the detection signals along one screen edge. The extent of the covered area in FIG. 1, in which stylus 931 has a narrow nib, is shorter than that of FIG. 2, in which stylus 931 has a wide nib, and this is reflected in the lengths of the detection signal peaks.

  • FIG.4 shows a light-based touch screen 800 for an ATM surrounded by rows of light emitters 200 and light receivers 300.
  • a keypad for entering a PIN is presented.
  • a credit card 904 having an embedded RFID tag 780, as a pointer, a user enters a PIN on screen 800. Every time credit card 904 touches screen 800, a touch detection signal is sent to calculating unit 770 that activates RFID reader 781 to read RFID tag 780.
  • RFID reader 781 sends the read information to calculating unit 770.
  • Calculating unit 770 combines the entered PIN code and the RFID information to authenticate the user. This method is explained with aid of FIG.5.
  • the method illustrated in FIG.5 begins at step 1002 polling the touch detectors, e.g., activating emitters 200 and detecting expected light at respective emitters 300.
  • the expected light values are sent from receivers 300 to calculating unit 770, which then determines whether a touch has occurred at step 1004. When expected light is absent a touch is assumed to have occurred. If a touch occurred, calculating unit 770 activates RFID reader 781 at step 1006 and reads RFID information therefrom. At step 1008 if no RFID information was read unit 770 ignores the touch input. If RFID information was read, unit 770 compares that input to previously stored RFID data at step 1010. The user is required to use the same object to enter each digit in the PIN. Thus, the RFID data must be identical at every touch.
  • -10- 770 compares the PIN entered by the user with user information read from RFID tag 780. If the data correspond to a single user, calculating unit proceeds to execute a transaction, e.g., dispense cash at step 1024. If the data do not correspond to a single user, calculating unit 770 cancels the operation at step 1022.
  • the same method can be applied to verifying a credit card holder before execution a purchase. In this case, the touch screen is embedded in a sales console.
