Abstract

A set of letter manipulatives and a board on which said letter manipulatives may be placed, where the board comprises an identification module that can identify the letter manipulatives placed on the board and communicate the identification to a computing device.

Claims (54)

1. A system comprising:

a set of manipulatable letters; and

a letter identification device configured to receive one or more manipulatable letters from the set of manipulatable letters, the letter identification device comprising:

a color sensor configured to determine an amount of colored light reflected by a manipulatable letter from the set of manipulatable letters, the manipulatable letter being received by the letter identification device; and

one or more processors configured to perform operations comprising:

identifying the received manipulatable letter based on the determined amount of colored light reflected by the manipulatable letter.

2. The system of claim I, wherein:

the color sensor of the letter identification device comprises at least one of a red light sensor, a green light sensor, or a blue light sensor.

3. The system of claim 1 , wherein:

the identifying of the received manipulatable letter is based on at least one of a determined first amount of red light reflected by the received manipulatable letter, a determined second amount of green light reflected by the received manipulatable letter, or a determined third amount of blue light reflected by the received manipulatable letter.

4. The system of claim 1 , wherein:

the letter identification device further comprises a light source of the colored light; and

the color sensor is configured to determine the amount of the colored light reflected by the received manipulatable letter from the light source to the color sensor.

5. The system of claim 4 , wherein:

the light source of the colored light comprises at least one of a red light source, a green light source, or a blue light source.

6. The system of claim 4 , wherein:

the color sensor is configured to determine at least one of a first amount of red light reflected by the received manipulatable letter, a second amount of green light reflected by the received manipulatable letter, or a third amount of blue light reflected by the received manipulatable letter.

7. The system of claim 1 , wherein:

each manipulatable letter in the set of manipulatable letters has a corresponding bottom surface with a corresponding color unique to that manipulatable letter among the set of manipulatable letters.

8. The system of claim 7 , wherein:

the identifying of the received manipulatable letter is based on the corresponding color of the corresponding bottom surface of the received manipulatable letter.

9. The system of claim I, wherein:

the letter identification device comprises one or more receptacles configured to receive one or more manipulatable letters from the set of manipulatable letters; and

the letter identification device comprises a camera aimed at the one or more receptacles of the letter identification device.

10. The system of claim 1 , wherein:

the letter identification device is further configured to communicatively couple with a computing device; and

the operations for which the one or more processors of the letter identification device are configured to perform further comprise:

communicating an identity of the identified manipulatable letter to the computing device.

11. A letter identification device comprising:

one or more receptacles configured to receive one or more manipulatable letters from a set of manipulatable letters;

a color sensor configured to determine an amount of colored light reflected by a manipulatable letter from a set of manipulatable letters, the manipulatable letter being received by a receptacle among the one or more receptacles; and

one or more processors configured to perform operations comprising:

identifying the received manipulatable letter based on the determined amount of colored light reflected by the manipulatable letter.

12. The letter identification device of claim 11 , wherein:

the color sensor comprises at least one of a red light sensor, a green light sensor, or a blue light sensor.

13. The letter identification device of claim 11 , wherein:

the identifying of the received manipulatable letter is based on at least one of a determined first amount of red light reflected by the received manipulatable letter, a determined second amount of green light reflected by the received manipulatable letter, or a determined third amount of blue light reflected by the received manipulatable letter.

14. The letter identification device of claim 11 , further comprising:

a light source of the colored light; and wherein:

the color sensor is configured to determine the amount of the colored light reflected by the received manipulatable letter from the light source to the color sensor.

15. The letter identification device of claim 14 , wherein:

the light source of the colored light comprises at least one of a red light source, a green light source, or a blue light source.

16. The letter identification device of claim 14 , wherein:

the color sensor is configured to determine at least one of a first amount of red light reflected by the received manipulatable letter, a second amount of green light reflected by the received manipulatable letter, or a third amount of blue light reflected by the received manipulatable letter.

17. The letter identification device of claim 11 , wherein:

each manipulatable letter in the set of manipulatable letters has a corresponding bottom surface with a corresponding color unique to that manipulatable letter among the set of manipulatable letters.

18. The letter identification device of claim 17 , wherein:

the identifying of the received manipulatable letter is based on the corresponding color of the corresponding bottom surface of the received manipulatable letter.

19. The letter identification device of claim 11 , further comprising:

a camera aimed at the one or more receptacles of the letter identification device.

20. The letter identification device of claim 11 , further comprising:

a communication interface configured to communicatively couple with a computing device; and wherein:

the operations further comprise:

communicating an identity of the identified manipulatable letter to the computing device.
