Information Input Device and Non-Transitory Computer-Readable Medium Storing Computer-Readable Instructions

An information input device comprising:

• a detection portion configured to detect a position of a writing portion being in contact with or close to the detection portion;
• a processor;
• and
• a memory configured to store computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the information input device to perform processes comprising:
• acquiring position information at a predetermined time interval, the position information being information of the position detected by the detection portion;
• setting, as first position information, information indicating one of positions indicated by the acquired position information;
• determining whether a distance between a position indicated by the set first position information and a position indicated by second position information is less than a threshold value, the second position information being position information acquired after the first position information is acquired;
• and
• storing, as information configuring trajectory information, the second position information in a storage portion in response to determining that the distance is not less than the threshold value, the trajectory information being information indicating a trajectory of the writing portion,
• wherein
• the setting, as the first position information, the information indicating the one of the positions indicated by the acquired position information includes setting, as the first position information, the second position information stored in the storage portion.
