They may be a technologically oriented lot, but even the most dedicated of engineering students know the value of a warm hug from a loving girlfriend -- especially those who can't get a date. Three students from the University of Tsukuba in Japan have created a device called the "Riajyuu Coat," or fulfillment coat, to let their lonelier peers experience the sensation of being hugged from behind by a giggling, breathless female. "It looks like a normal coat at first," says software Engineer Kota Shinbayasgi in a video uploaded by his team to Japanese video site NicoNicoDouga. "Users wear this coat, fasten the belt and wear headphones. Now it is prepared..." The belt he refers to contains two robotic pincers controlled by a motor at the back of the garment. A pair of USB headphones worn by the user blast the sound of footsteps running up from behind once the belt is fastened. The pincers then squeeze the coat wearer's body from behind, simulating a woman's embrace, while a pre-recorded voice sourced from a popular Anime actress whispers things like "I'm sorry, were you waiting?" and "Guess who?" "If I have a girlfriend I think it is a good situation that she suddenly hugs me when I wait for her at the station," said developer Maito Omari in the video. The project's hardware engineer Hikaru Sugira elaborated "The concept of this device is everyone can get the feeling of having a girlfriend." Riajyuu is Japanese slang for someone "who is pleased with their life outside the Internet" according to Kotaku, who likens this device to the robotic butt developed by researcher Nobuhiro Takahashi at another Japanese university last year. Takahashi is also the brains behind a headline-making kissing simulator and Sense-Roid virtual hugging vest.padding-bottom: 100%;"> 他們也許是科技狂人，但即使是最專注於研究的工程學學生也知道來自深情女友的一個溫暖擁抱的價值——特別是那些沒人和自己約會的男生。 日本筑波大學的三個學生髮明瞭一種名爲“滿足外套”（Riajyuu coat）的裝置，讓孤獨的同伴們能體驗到被咯咯笑的呼吸急促的女孩從後面抱住的感覺。 軟件工程師Kota Shinbayasgi在他的團隊上傳到日本視頻網站NicoNicoDouga的一個視頻中說：“乍看上去這就像件普通的外套。用戶穿上這件外套，繫緊腰帶，帶上耳機。準備就緒……” 他所指的腰帶包含由外套背面的發動機控制的兩個機器人手臂。 一旦繫上腰帶，用戶就能從戴着的USB接口耳機裏聽到從背後跑過來的腳步聲。 這時候機器人手臂就會模仿女人從後面把穿外套者的身體抱緊，同時用戶會聽到預先錄好的流行動漫女主角的聲音輕輕地說“對不起，你久等了吧？”或者“猜猜我是誰？” 該外套的研發者Maito Omari在視頻中說：“如果我有女朋友，當我在車站等她時她突然把我抱住，我覺得這樣的情景很美好。”該項目的硬件工程師Hikaru Sugira解釋說：“這一裝置的理念是讓每個人都能體會到有女朋友的感覺。” Kotaku說，Riajyuu在日本俚語中指“在網絡外的現實生活中感到很滿足的人”，他認爲這一裝置和去年另一所日本大學的研究人員Nobuhiro Takahashi研發的機器人屁股很類似。 Takahashi也是曾經登上頭條新聞的接吻模擬器和Sense-Roid虛擬擁抱夾克的研發者之一。
