如今，乘車已經是日常生活之基本，暈車作為動暈症的一種類型，時常發生在旅途中使用手機閱讀。其根本原因為視覺、前庭覺和本體覺之間感知訊息的衝突。服用暈車藥或許有助於改善狀況，但它卻有嗜睡和視力模糊的副作用，而且使用者大多偏好在乘坐過程中從事各種活動。因此我們嘗試透過設計將使用者的視覺訊息與實際的汽車移動同步，以達到感覺統合、減緩暈車的發生。
本研究旨在由生理角度探討，讓使用者不僅能減緩暈車，更能得到有意義且豐富的乘車體驗，因此分別構思出具身認知(embodiment)、預期(anticipation)、感知(awareness)三種創新概念之閱讀輔助裝置，於汽車內進行實地實驗。我們利用額頭膚電值、心率、及姿勢晃動值等客觀量測，以及使用主觀動暈評分及閱讀文章之效能進行設計分析。結果顯示具身認知、預期、感知之概念裝置皆可減緩乘車閱讀暈車，亦不影響閱讀文章之效能，其中，感知策略之概念裝置最具顯著效果。本研究所帶來的成果與經驗，可應用於未來科技所衍生之動暈症相關設計研究上，如自動駕駛汽車、虛擬實境等。

Traveling by car has become a routine in our daily lives nowadays. Carsickness is a specific form of motion sickness that often occurs while reading on a smartphone during travel. It results from the sensory conflict between the visual, vestibular, and proprioceptive systems. Taking anti-motion sickness medicine could be helpful. However, it can cause sleepiness and blurry vision. Besides, users prefer to perform various activities, such as reading, while traveling by car. We suggest synchronizing users’ perceived visual information with actual car movement as a strategy to improve sensory integration and reduce the symptoms of carsickness.
The research explores users’ motivation for in-car non-driving tasks during travel and aims to solve carsickness symptoms from a physiological perspective. We designed auxiliary devices using embodiment, anticipation, and awareness strategies. To evaluate the devices with different strategies, we conducted experiments in the field and analyzed the effectivity of the devices in reducing symptoms of motion sickness, the efficiency of reading with the devices, and overall user experiences. The evaluation for motion sickness was done through self-reported questionnaires and physiological measurements, including forehead galvanic skin response, heart rate, and postural instability. The result shows that all strategies are beneficial for both carsickness and reading performance, while the awareness strategy is most effective. The experience shall be able to be applied in related design researches about motion sickness caused by future technologies, such as autonomous cars and virtual reality.
