摘要

在這篇論文中，我們提出兩種實體使用者介面與可攜式物理界限互動。第一個系統是 GaussMarbles 球形實體介面，不同於過去研究中磁性物件的設計，我們所提出以具磁性的正多面體結構設計來支援球體的三維互動操作。當球在滾動時，這樣設計下磁場形狀提供穩定的特性讓類比式霍爾感測網格得以即時追蹤球形物體在近平面的三維空間位置。我們同時提出開發流程來讓使用者簡單地製造組裝磁性球體。我們以三種層次的實體化方式展示多種 GaussMarbles 與可攜式物理界線的互動應用。

為了達到物體多種身分的辨識與保留高自由度的操作，我們提出第二個系統是 GaussRFID，結合磁鐵與 RFID 標籤所設計的實體互動開發工具。這樣的系統由兩個元件組成：一是 GaussTag，一個具有磁性的 RFID 標籤，二是 GaussStage，一個實體使用者介面設計平台結合了類比式霍爾感測網格與 RFID 讀取器，GaussStage 可以偵測裝置周圍 GaussTag 的 ID、三維位置與部分三維旋轉角度資訊，並提供簡單的方式讓使用者可以結合不同類型的物理界限，與具延伸性的輸出功能。我們所提出的兩個系統探討了實體物體與物理界限的組合在可攜式平台下的互動設計，並為設計師、研究者提出完整的開發工具可以更容易去創造豐富的實體介面互動應用。

This thesis presents two tangible user interfaces for interacting with portable physical constraints. The first system, GaussMarbles, a system of spherical magnetic tangibles. Unlike previous design of magnetic tangibles, the proposed magnetic polyhedron design support 3D interactions. When the ball is rolling, the shape of magnetic fields provides robust features for the analog Hall-sensor grid to track the near-surface 3D position in real-time. We also propose a simple procedure to fabricate the proposed magnetic sphere with ease. Several applications are demonstrated to show possible interactions between the GaussMarbles and physical constraints in various levels of embodiment.

To achieve rich-ID an high-DOF, we present the second system, GaussRFID, a magnetic-RFID development kit for embedding interactivity by creating physical artifacts. The hybrid RFID and Magnetic-field tag sensing consists of two major components: GaussTag, a magnetic-RFID tag combined with a magnetic unit and a RFID tag, and GaussStage, the tag reader as well as a TUI design platform combined with an analog Hall-sensor grid and an RFID reader. A GaussStage reads the ID, 3D position, and partial 3D orientation information of a GaussTag nearby the sensing platform, and provides simple interfaces for users to incorporate different types of physical constraints, making display and actuator modules in a plug-and-play fashion. The two proposed approaches explore the token+constraint interfaces on the portable platform and complete a toolkit for designers and researchers to create various tangible interactions with physical constraints.
