Half-Implant: 情報提示のための半侵襲型装置の提案Half-Implant: Device for Hand Gesture Feedbackjpnhttp://id.nii.ac.jp/1001/00099041/Technical Reporthttps://ipsj.ixsq.nii.ac.jp/ej/?action=repository_action_common_download&item_id=99063&item_no=1&attribute_id=1&file_no=1Copyright (c) 2014 by the Information Processing Society of JapanH2L株式会社早稲田大学岩崎, 健一郎玉城, 絵美従来のハンドジェスチャ入力のためのフィードバックデバイスには,電源供給としてバッテリが必要不可欠であった.そのため,装置が大きくなるか有線となり,特定の状況で短期的にしか利用できないという問題があった.本報告書では,RF(Radio Frequency) から電源供給を行うことで,バッテリが不要となったフィードバックデバイスを提案する.また,提案デバイスを様々な状況で長期的に利用できるように,爪の上に固定できる半侵襲性を持たせた.提案デバイスに LED もしくはバイブレーションをとりつけて,その操作性について実験を行った.フィードバックデバイス装着時に任意の位置を指し示す実験では,提案デバイスを付けてない状況ではタスク成功率が 97%であったのに対して,LED もしくはバイブレーション型の提案デバイスを付けている状況では,タスク成功率は 100%であった.また,提案デバイスを付けた状態では,タスク試行時間も 12.3%短縮した.最後に,提案デバイスの社会的受容性を調査し,今後の利用例について議論した.Hand gesture feedback systems using tactile or visual information can only be used in given situations because of the limitations of the device features such as the need for a battery. In this paper, we propose a half-implant device located on the fingernail. The half-implant device consists of a radio frequency (RF) receiving antenna, small electronic parts, and UV gel. The UV gel is used to glue the parts onto the user's nail and cover the parts meant to be waterproof. The device receives power from the RF antenna; therefore, it does not require a battery to function. It notifies whether the finger is in a gesture space by lighting an LED or activating a vibration motor. The primary benefit of this device is that the user can feel hand gesture feedback, anytime and anywhere. The device can be placed on the users' fingernail for approximately three weeks. To verify the devices' influence on the users' gesture task, we conducted a preliminary user study. The task success rate was 100% over the sessions with tactile and visual feedback and 97% without feedback. The experiment revealed that the tactile notification reduced the task time by 12.3% compared to that of the test with no feedback. We also investigated user's acceptability of this kind of technology. It revealed that this technology is acceptable only when it can be removed in the user's will and used in daily-life.AA1155524X研究報告グループウェアとネットワークサービス(GN)2014-GN-9124182014-03-062014-03-06
