摘要

本篇論文提出了兩種馬達陣列的系統的設計,DynaFrame 與 Dyn- aBase,其目的在於對觸控筆進行動態約束,以輔助或限制觸控筆在顯 示器上的筆劃輸入。DynaFrame 外形類似框架包圍在螢幕周圍,由機 器人手臂作為驅動,從而可以控制和約束觸控筆在屏幕上方的移動軌 跡,DynaFrame 的優點在於擁有近螢幕表面的三維空間運動能力,但 手臂在運動過程中會遮擋螢幕上面的內容。DynaBase 與 DynaFrame 類 似,由機械手臂驅動,位於螢幕下方,手臂末端綁定磁性轉軸,透過 磁性來操縱屏幕上方的動態約束,由於用戶會將畫筆放置在該約束上, 以此來控制觸控筆的輸入。DynaBase 基本不會遮擋螢幕的內容,但失 去了近螢幕表面的三維運動能力。
本文提出的兩種動態約束系統,其裝置外形體積符合可便攜的需 求。在儘量減少螢幕內容遮擋的前提下,能夠動態地輔助或限制使用 者觸控筆的互動。不同的約束方式-剛性約束以及柔性約束為用戶提 供了準確可靠且具有表現力的力反饋感受。
我們在這篇論文中,我們實作了兩種動態約束裝置,評估其技術細 節,并詳細描述了設計考量,基於兩者的不同硬體設計方式,以及約 束形態的不同,設計了相對應用場景。最終我們探討 DynaFrame 以及 DynaBase 未來可能的展望。

This work proposed two designs of actuator array system, DynaFrame and DynaBase, to realize dynamic physical constraints on portable displays for facilitating stylus input. DynaFrame is a frame-like device consists of a miniaturized robot arm surrounding the display, allowing for manipulating the stylus placed on the display surface in the near surface 3D volume. DynaBase is a basestation-like actuation platform consists of an robot arm controlling a magnetic shaft , which can manipulate a physical constraint placed on a portable display that user docked on it.
Both of dynamic constraint systems are portable, provide active force feedback as expressive and precise hard or soft constraints. The provided dynamic constraints therefore facilitate users performing stylus interactions without introducing significant occlusions on the portable display.
Furthermore, we implement the system and evaluate its technical features. In this paper, we describe the details of the design and implementations of the device, along with applications, technical evaluations, and future prospects.
