Summary: | To provide an information processing apparatus, method and program capable of automatically and timely detecting various information obtained through a writing operation using an input device.SOLUTION: An information processing apparatus 16 is provided with a data acquisition unit 26 for acquiring stroke data 50 indicative of a set of coordinate values representing an indicated position and a pen pressure value representing magnitude of pen pressure sequentially acquired through a writing operation using an input device 14; a feature quantity generating unit 28 for generating a feature quantity set relating to a stroke group 54 written through the writing operation using the acquired stroke data 50; and a specificity detecting unit 32 for performing detection processing on the generated feature quantity set and detecting, from the stroke group 54, a specific stroke 56 in which the pen pressure value or the time change of the pen pressure value is unique.SELECTED DRAWING: Figure 1
【課題】入力デバイスを用いた筆記操作を通じて得られる各種情報を自動的かつ適時に検出可能な情報処理装置、方法、及びプログラムを提供する。【解決手段】情報処理装置16は、入力デバイス(14)を用いた筆記操作を通じて順次検出される指示位置を示す座標値及び筆圧の大きさを示す筆圧値の集合を示すストロークデータ(50)を取得するデータ取得部26と、取得されたストロークデータ(60)を用いて、筆記操作により筆記されたストローク群(54)に関する特徴量セットを生成する特徴量生成部28と、生成された特徴量セットに対して検出処理を施し、ストローク群(54)の中から筆圧値又は該筆圧値の時間変化が特異である特異ストローク(56)を検出する特異性検出部32と、を備える。【選択図】図1 |
