Gestify —给视频加上手势操控的浏览器扩展，支持安卓版 Edge 和 Firefox

Gestify 是一个浏览器扩展，为所有网页上的 HTML5 视频添加手势控制。用过手机视频 APP 的都知道：左右滑快进、长按倍速、双击跳转、上下滑调音量——这些操作已经是肌肉记忆了。但在浏览器里看视频？只能点点点。 Gestify 把这些手势搬到了浏览器里，PC 和安卓手机都能用。手势清单 | 手势 | 效果 | ||| | 左右滑动 | 快进/快退（下滑取消） | | 长按 | 2× 倍速播放（松手恢复） | | 长按 + 上滑 | 锁定当前倍速 | | 双击左侧 | 后退 10 秒 | | 双击右侧 | 前进 10 秒 | | 双击中间 | 暂停/播放 | | 右侧上下滑 | 调节音量 | | 左侧上下滑 | 调节亮度 | 支持的网站所有使用标准 HTML5 <video 的网站，包括但不限于： YouTube、Netflix、Disney+、Bilibili、优酷、爱奇艺、腾讯视频、Twitch、TikTok、Vimeo、Udemy、Coursera、TED、LinkedIn Learning…… 安卓支持 Gestify 支持安卓版 Edge 和安卓版 Firefox。手机浏览器全屏看视频本来没有任何手势，装了 Gestify 后体验直接对标原生 APP。特别适合不想装一堆视频 APP、只想用浏览器搞定一切的用户。仅视频全屏时生效，非全屏自动禁用安装链接 | 平台 | | ||| | Chrome | | | Edge | | | Firefox | | | Android | 在 Edge / Firefox 手机版扩展商店搜索「Gestify」 |

I've always been fascinated by how differently people perceive color. So I built DialIn — a cyberpunkthemed color memory game that tests your ability to remember and reproduce colors. gameplay How It Works The concept is deceptively simple: 1. See a color flashed on screen 2. Remember it 3. Recreate it using a color picker 4. Get scored on how close your guess is You play 5 rounds per game. The better you score, the higher your level climbs. Struggle too much? You drop down. It's addictive in that "just one more try" kind of way. The Scoring System This is where it gets interesting. I didn't want a simple "close or far" metric. I used CIEDE2000 — the same color difference algorithm used in professional color science. The scoring formula is an Scurve: javascript score = 10 / (1 + (deltaE / 25.25) 1.55) Where deltaE is the CIEDE2000 color difference between the original and your guess. This means: deltaE < 5 → You get 810 points (excellent match) deltaE ~ 25 → You get ~5 points (decent) deltaE 50 → You get 12 points (way off) There's also a hue bonus — if your hue is within 30° of the original, you get an extra 0.5 points. This rewards getting the "right color" even if saturation or brightness is off. Game Modes 🎨 Free Play Practice anytime, 5 rounds, automatic difficulty scaling through 5 levels. Higher levels introduce distractor colors to mess with your memory. ☀️ Daily Challenge Everyone gets the same 5 colors each day. Compete on a global leaderboard. Come back daily to build your streak. ⚔️ Color Duel Challenge a friend! Create a duel, share the link or a 6character code. Both players face the same colors and compare scores. Color Personality After each game, you get assigned a "color personality" based on your bias patterns: | Type | | ||| | 🎯 Precision Eye | Nearperfect color memory | | 🌈 Color Dreamer | Tends toward more vivid, saturated colors | | 🌙 Shadow Watcher | Prefers darker shades | | ☀️ Light Chaser | Draws toward brighter tones | | 🔥 Warm Soul | Biased toward warm hues | | 🧊 Cool Mind | Leans toward cool hues | | 🎲 Free Spirit | No consistent pattern — unpredictable! | It tracks your bias history across games, so your personality evolves as you play. Tech Stack I deliberately kept it simple: Frontend: Vanilla HTML + CSS + JavaScript (no framework) Styling: CSS custom properties + Tailwindinspired utility classes Scoring: CIEDE2000 implemented in pure JS Backend: Cloudflare Workers (API routes) Database: Cloudflare D1 (SQLite) for Daily leaderboard Hosting: Cloudflare Pages Domain: dialin.cc The entire frontend is under 50KB (unminified). No build step, no bundler, no nodemodules. Just files served directly. Why No Framework? For a game like this, the DOM interactions are straightforward — show/hide sections, update scores, render color blocks. A framework would add complexity without clear benefit. The codebase is clean enough that vanilla JS is actually easier to reason about. Design Choices Cyberpunk Aesthetic The dark theme uses CSS custom properties with neon accents (cyan, pink, purple). There's a Matrixrain background effect and scanline overlay. The light theme is available for those who prefer it. MobileFirst The game works equally well on phone and desktop. On mobile, the nav bar collapses to a "⋯" menu. Touchfriendly color picker with large hit targets. i18n Full English and Chinese support. Language detection from navigator.language, with manual toggle. What I Learned 1. navigator.share Is Not MobileOnly Desktop Chrome now supports the Web Share API. If you're using it to detect mobile, you'll have a bad time. Use userAgent or matchMedia instead. 2. Clipboard API Is Unreliable in Embedded Browsers WeChat, Feishu, and other embedded browsers don't support navigator.clipboard. The oldschool textarea + document.execCommand('copy') is still the most reliable crossbrowser copy method. 3. CIEDE2000 Is Worth It Simple RGB distance produces weird results — colors that look similar to humans score poorly, and vice versa. CIEDE2000 actually matches human perception. The math is complex but there are good JS implementations available. 4. Cloudflare Pages + D1 Is a Sweet Spot For a small project like this, having a SQLite database at the edge with zero configuration is amazing. The Workers API routes are just JavaScript functions. What's Next [ ] More detailed stats and progress tracking [ ] Duel tournament mode [ ] Custom color themes [ ] Accessibility improvements (colorblind mode?) Try It dialin.cc — No signup required, works on any device. I'd love to hear your feedback! What's your color personality? 🎨 Follow me on X/Twitter for updates.
