▍大謙科技 DACIAN TECHNOLOGY MATERIAL CO., LTD.
Booth No. Q0430
大謙科技材料在不影響到過濾與保護效果下,推出的克微粒奈米薄膜口罩。大謙科技的薄膜技術可達N95等級的過濾效果,讓穿戴者更安心,同時解決戴N95引起換氣不順暢的問題。
克微粒防護口罩是經美國Nelson測試油性粒子(DOP)過濾效果達98%,可排除汽車廢氣油汙粒子,相當於 P95口罩等級,然而此款口罩不僅能排除廢氣油汙粒子,更可以阻隔大氣中重金屬粒子,是此款口罩的指標性功能。
Dacian Technology Material’s :dc Microparticle Stopper Mask” uses its membrane technology to eliminate traditional issues that plague standard surgical masks, without sacrificing usability and filtration efficiency.
Dacian’s masks passed the DOP test carried out by Nelson Lab with 98% oily-particle filtering capabilities in the U.S. This is crucial for more diverse use of these masks, as N95 typically can only block non-oily particles.

🌳 文章標題:如何執行可用性測試-從頭到尾6步驟
對於網站、行動 APP或任何軟體產品,可用性測試至關重要。 根據 Forbes,許多大品牌運用可用性設計與 UX測試讓企業更上一層樓。 IBM報告表示每一元對可用性的投資都會帶出10~100元的回收。 Amazon 的貝佐斯在建入口網站的第一年對於可用性的投資是行銷的100倍。
本篇給予6個重要步驟,讓你一步一步完成可用性測試
1. 建一個原型或產品來測試 -- 需有很清楚定義的目標,才能知道哪些是重要功能,選擇什麼度量比較合適
2. 起草測試計畫--兩個重要問題: 要測試什麼, 如何度量結果。可採取 open-ended 或 specific tasks/questions
3. 召集測試參與者 -- 由目標客戶或理想的客戶Persona( ✍ http://bit.ly/2I3kpOH )中發掘,用對管道召集
4. 執行測試 -- 到企業安排現場有人主持與指引的測試,遠端在家平時樣子的測試
5. 將測試結果做紀錄與文件化--記錄方法: 試算表筆記、錄音、抓螢幕或錄影、參與者填問卷或回饋、成功率計算、錯誤率計算。PPT 簡報: 背景、測試方法、結果、發現與建議、總結
6. 修正問題並改善性能-- 好好運用測試的發現,修改錯誤與改善使用者經驗。對每個發現給與多個解決方案,如果一個方案能解決多個問題,那麼這可排最優先執行。
不要害怕 UX 測試過程 - 這是推向市場前對產品整體運作的整合工作。儘管開展前期需要做許多事和大量研究來確定最佳測試環境將應是怎樣,但投資回報率將會很高,並且會證明每一步需要的花費和努力都值得。

Got my hands on the brand new RF 70-200 F4 IS USM for a couple of days. I tried my best to bring it out on a couple of shoots (not many due to the lockdown) to test it out. This isn't a review because I believe reviews should come from long term use, but rather and in depth first look/impressions of this lens. I wanted to answer a few questions such as size, weight, bokeh and usability. After a few days of testing out the lens, I feel I have a good idea on what this lens is good at and where it fails. I also briefly compare it to the 2.8 version. Hope this video helps!

While the Sony A7SIII is mainly for video, as a photographer, I find out whether it's great for photography too and test whether it'll have a place in my workflow for photos.
I break down the three areas that are important to me when evaluating a camera, and we also do a POV street photography session.
Check out my homie @Demas Rusli who I shot this with.

I unbox the Sony a6500 (http://amzn.to/2iJIbmk) and test it on the Zhiyun Crane 3-axis gimbal (http://amzn.to/2ssy3I3). Learn filmmaking from me! https://myfilm.school/a6500-Unboxing-Gimbal-Test

The Sony a6500 is an update to the a6300, adding Steadyshot Inside (IBIS) and touchscreen autofocus. I tried using these new features on the Zhiyun Z1 Crane 3-axis gimbal to see if they improve performance and usability.
