Research was conducted regarding a display that presents digital information using bubbles. Conventional bubble displays require moving parts, because it is common to use air taken from outside of the water represent pixels. However, difficult increase number pixels at low cost. We propose liquid-surface clusters generated electrolysis, and present cup-type device BubBowl, which generates 10×10 pixel dot matrix pattern on surface beverage. Our technique requires neither gas supply nor parts....
A palladium-catalyzed regioselective three-component coupling of ynamides was developed. The reaction proceeded smoothly to furnish the desired products when carried out at 70 °C in acetonitrile/water with potassium carbonate presence 2.5 mol % Pd2(dba)3·CHCl3 without a ligand. Various iodides and boronic acids were used this reaction, carbon-carbon bond formed satisfactory regioselectivity from ynamides.
We propose a method for controlling device that draws letters and illustrations on large, flat surfaces. Similarly to conventional inkjet printers, the ejects volume of water from its nozzle, with droplets then forming dots surfaces such as soil, concrete, sand. Both direction nozzle pressure can be controlled enable draw arbitrary two-dimensional patterns within semicircular region radius six meters. The illustrations. have investigated pressure, shape droplet size in order avoid further...

This pictorial presents a novel method to render color patterns using electrolysis applied onto open wet surfaces. By implementing electrodes within object and electrifying them, can occur generate ions. We designed color-forming display indicators reacting with such according the shape of electrode. reversing polarity generating reversed-polarity ions, it is possible fade existing pattern contrasting color. The proposed does not require moving parts; thus, low cost easy compact. Also, some...
Research was conducted on a digital information display using electrolysis bubbles. Although the research mainly focused displays in daily life, ephemerality of bubbles is also promising method for dynamic art installations. In this paper, we present two novel artworks bubble mechanism. First, "UTAKATA," ticker-like display, running-water channel. Seven electrodes are placed linearly channel bed, and they generate text messages dots that drift toward lower end Second, "Bubble Mirror," which...

The proposed used various...
To add haptic feedback and tactile cues of a physical interface to interaction with mobile touch displays, several passive systems have been proposed as Tangible User Interfaces (TUIs). The from such objects can be customized by changing their shape structure but cannot changed dynamically. Therefore, we propose simple TUI that provide dynamic on device. We use an electromagnet embedded in the tangible object magnetic sheet fixed back An electric current flowing through customizable pattern...
Research has been conducted regarding 3D food printing that additively manufactures edible objects. Some studies control the texture of printed foods by creating an intricate internal structure, which is limited resolution can be with soft paste-like foods. This study proposes a method for controlling 3D-printed gummy candy selectively generating fine foam structures inside using electrolysis. We establish technique bubbles in dough determining optimal material properties, developing...
We propose UTAKATA, an ephemeral display device that presents information by using floating clusters of bubbles. In our previous study, we implemented electrolysis bubble drinkable beverages. Although clear bubbles could be created in short times, they did not disappear for a long time; consequently, the refresh time period was considerably long. To overcome this deficiency, present ticker-like running-water channel. establish display, linear array seven electrodes is fabricated on bottom...
We evaluated the development of a social support educational program on future supporters. The intervention trained youths in their 20s and 30s who are providing or will provide to mentally vulnerable youths. conducted brief interviews with 69 participants, analyzing data through content analysis. Most participants found useful terms meeting new peers, gaining techniques for supporting others, relaxing assuring competence others. There were concepts that developed, but not aware until...

電気分解により発生する気泡を画素として用いる情報表示手法が筆者らにより提案されている[1].この研究の提案手法は,日常的な情報表示装置として利用されることが想定されていた.一方で,泡は消えやすく儚い性質を持っており,インタラクティブなアートやエンターテインメント作品のための素材としても有望であると考えられる.しかし,従来の電気分解気泡表示は応答速度が低く,低画素のバイナリ表示であるため,表現の可能性が制限されていた.本研究ではこの課題を解決し,アート作品への応用を模索する2点の気泡表示デバイスを開発する.1点目は,流れる水面にティッカー状の泡表示を行う"UTAKATA"である.水路の底面に電極を直線状に配置し電気分解を行うことで,泡によるメッセージを水路の下流に向かって流しながら動的に表示する.2点目は,水盤に対面したユーザの顔を水面に泡で表示する鏡のようなディスプレイ"Bubble Mirror"である.これは,32×32個の電極を用いて,8段階のグレースケールの泡による顔画像を水面に表示する.本稿ではこれらのデバイスの実装と表示性能の評価について報告する.
