A computer programme has been used to predict how people are feeling when they type.In a study participants were asked to type a particular phrase and the programme then estimated if they were happy, sad and so on.
Remarkably it was correct 70 per cent of the time, and the findings could lead to smarter artificial intelligence in the future.
The study published in the journal Behaviour and Information Technology was carried out by researchers at the Islamic University of Technology in Bangladesh, reports Live Science.
In the research 25 people ranging from 15 to 40 years old were asked to retype two paragraphs from Alice's Adventures in Wonderland by Lewis Carroll.This allowed the programme an opportunity to understand how their emotions changed their typing style.Moods tested were joy, fear, anger, sadness, disgust, shame and guilt.
据《衣食住行科学研究》(Live Science)报导，此项公布在《个人行为与信息科技》(Behaviour and Information Technology)刊物上的研究为孟加拉国伊斯兰科技学院的研究工作人员所进行。该研究中，25名年纪在15到40岁中间的参与者被规定反复输入来源于刘易斯·卡罗尔(Lewis Carroll)的《爱丽丝梦游梦幻仙境》(Alice's Adventures in Wonderland)中的几段话。这给该程序出示一个了解情绪如何更改打字设计风格的机遇。被检测的情绪包含欢悦、害怕、恼怒、忧伤、厌烦、惭愧和愧疚。
The result was that the programme could identify a person's mood correctly 70 per cent of the time.It was most successful in identifying joyfulness with an 87 per cent success rating, while sadness was the least accurate at 60 per cent.
The researchers noted that the participants were less likely to input data when they were in a bad mood, which may explain the inaccuracy of the latter result.
