Development of an Intention Estimation Model Based on Gaze and Face Information for Electric Wheelchair Operation Support

Higa Sho, Yamada Koji, Kamisato Shihoko

IEEJ Transactions on Electronics, Information and Systems ( The Institute of Electrical Engineers of Japan )  142 ( 4 ) 491 - 498   2022.04 [ Peer Review Accepted ]

Type of publication: Research paper (scientific journal)

　View Summary

<p>In recent years, various user interfaces have been developed to meet the diverse needs of physically disabled persons. In this paper, we developed a method to identify gazing and facial movements based on gaze time and eye/face information and developed an electric wheelchair that can be operated with the user's "natural gazing and facial movements. This intention estimation model is composed of 1DCNN and LSTM layers. First, 1DCNN is used to extract features from gaze and face information, and then the extracted features are input to LSTM to estimate the user's intentions regarding movement. The evaluation experiments suggest that the combination of gaze and face information improves the estimation accuracy and contributes to the classification. Furthermore, it was confirmed that adding a convolutional filter layer to the LSTM layer improved the accuracy.</p>

　View Summary

<p>深層学習によって様々な分類問題が解決されているが，分類カテゴリ毎のデータ量が不均衡な問題を扱う場合，多くの課題がある．不均衡データへの対策として，少量カテゴリのデータ量を増加させ均衡化する手法がある．これをかさ増しと呼び画像処理分野ではノイズの付与や回転による方法が一般的である．最近ではGenerative Adversarial Network: GANによる画像生成手法を用いる場合がある．一方で，自然言語処理の分野では有効なかさ増し手法はいまだ確立されておらず，人手によるかさ増しが行われている．人手によるかさ増しではルールの設計など負担が大きく，機械的なかさ増し手法が必要となる．しかし，文章生成における機械的なかさ増しは画像生成に比べ不安定である．これは文章の特徴獲得の難しさが原因だと考えられる．そこで本論文ではグラフ情報に注目した機械学習による文章生成手法を提案する．CaboChaによって生成されたグラフ情報をGraph Convolutionにより畳み込み処理する．提案するGANにより生成されたかさ増し文章を3つの計算実験により評価し有効性を示した．</p>

　View Summary

<p>Facial expressions play an important role in communication as much as words. In facial expression recognition by human, it is difficult to uniquely judge, because facial expression has the sway of recognition by individual difference and subjective recognition. Therefore, it is difficult to evaluate the reliability of the result from recognition accuracy alone, and the analysis for explaining the result and feature learned by Convolutional Neural Networks (CNN) will be considered important. In this study, we carried out the facial expression recognition from facial expression images using CNN. In addition, we analysed CNN for understanding learned features and prediction results. Emotions we focused on are "happiness", "sadness", "surprise", "anger", "disgust", "fear" and "neutral". As a result, using 32286 facial expression images, have obtained an emotion recognition score of about 57%; for two emotions (Happiness, Surprise) the recognition score exceeded 70%, but Anger and Fear was less than 50%. In the analysis of CNN, we focused on the learning process, input and intermediate layer. Analysis of the learning progress confirmed that increased data can be recognised in the following order "happiness", "surprise", "neutral", "anger", "disgust", "sadness" and "fear". From the analysis result of the input and intermediate layer, we confirmed that the feature of the eyes and mouth strongly influence the facial expression recognition, and intermediate layer neurons had active patterns corresponding to facial expressions, and also these activate patterns do not respond to partial features of facial expressions. From these results, we concluded that CNN has learned the partial features of eyes and mouth from input, and recognise the facial expression using hidden layer units having the area corresponding to each facial expression.</p>

Estimating Age on Twitter Using Self-Training Semi-Supervised SVM

人工生命とロボットに関する国際会議予稿集 ( 株式会社ALife Robotics )  21   228 - 231   2016.01

Type of publication: Research paper (scientific journal)

　View Summary

The estimation methods for Twitter user's attributes typically require a vast amount of labeled data. Therefore, an efficient way is to tag the unlabeled data and add it to the set. We applied the self-training SVM as a semi-supervised method for age estimation and introduced Plat scaling as the unlabeled data selection criterion in the self-training process. We show how the performance of the self-training SVM varies when the amount of training data and the selection criterion values are changed.

　View Summary

<p>In nearby special support schools, the practice of driving a motorized wheelchair using a joystick has been conducted for physically disabled children. However, physically disabled children require support and adjustment of the equipment corresponding to their disabilities because it is difficult to operate a joystick in a specific direction owing to their disabilities. In this study, we develop a joystick-type controller that can be automatically adjusted to the reaction angle suitable for the actual conditions of physically disabled children. Moreover, we conduct a quantitative evaluation of upper limb motion when operating the joystick-type controller that we developed to examine the effectiveness of the proposed method. The evaluation results confirm an effective improvement in the operability when the acquired reaction angle is suitable for the actual conditions of the user by the proposed method.</p>

Type of publication: Research paper (scientific journal)

　View Summary

Our emotion estimation refers to estimation of a reader's sentiments and feelings after they read a narrative (i.e., post-reading emotion types). The emotion types manifest in a reader's feelings combine to form diverse and various patterns. To elicit this phenomenon, we here attempt to estimate readers' emotional patterns based on their cognitive appraisals of the work. This paper describes our cognitive appraisal methodology, variation in readers' emotion types due to differences in their cognitive appraisals, and report and discuss the results of emotion estimation experiments in which a reader performs a cognitive appraisal of the text of a narrative.
