Gain Magical Control Over Your Music Player With Flutter

It’s a bit like Minority report. Just raise your hand and your computer responds with an action. Motion-based controls with your hands, now more common with modern gaming consoles (PlayStation Move and XBOX Kinect), still feels a bit futuristic.

On personal computers and modern tablets, peripheral input and touch-based gestures won the race against camera-based gesture recognition. Still, some developers are in love with the idea of controlling devices without any actual hands-on. In small doses, this can be fun and useful. This is the case with Flutter, developed by a large team of developers at BotSquare.

Flutter is a small tool for recognizing motion gestures on OS X, which recognizes you via a webcam (iSight or external) to control your favorite music player. After downloading it, you have work through a tutorial to get to become familiar with the hand gestures. Flutter then sits in the background, with your Mac’s iSight camera on (obviously required for running Flutter) and awaits your actions.

The current version of Flutter (0.1.237 — don’t be afraid, it’s not a beta version, the developers just want to add more features before calling the app 1.0) supports three gestures: a flat open hand, and a fist with your thumb either pointing to the right or the left. Do those gestures in front of your webcam, and Flutter will recognize them and do the action associated with them. To make sure the app recognizes your hand’s action, you have to keep it one to four feet away from the camera.

With the open hand gesture, you can play and pause your music. Using the thumb either pointing to the right or left you go to the next or previous track. The Flutter team is working hard to implement more gestures such as volume control (I suggest a single index finger pointing upwards or downwards respectively for this one).

All three gestures work well in the current version — you just have to get used to the fact that you often need to move your hand a bit to make the camera notice it. Knowing where to position yourself at first so that your hand is inside the viewing area of your camera can be tricky at first. But after a while you also get used to it; when Flutter recognizes you it’s easy to use, looks like magic, and can be a very intuitive way of controlling your music player (the app currently supports iTunes, Spotify, VLC, and QuickTime; no Rdio support unfortunately).

Through the app’s drop-down menu, you can turn the camera on and off (for privacy and energy saving reasons), set Flutter to automatically launch at login, as well as report bugs and re-watch the aforementioned (very interactive and easy to understand) tutorial. The app also sends notifications to the Notification Center when you change apps to let you know that you’re still able to control the newly activated player with Flutter.

Flutter is a small app, although it’s not something I would recommend because not everybody needs it. However, I can imagine that lots of people would want to try it for the novelty of it. It’s a magic little piece of software that can be fun to use.

Flutter is available for free on the Mac App Store.

iTunes and App Store Reminders with Recall

I don’t like some of the changes of the new App Store in iOS 6. That’s not a secret. But there is a single annoyance that goes way back before the iOS 6 days, all the way to when the App Store was relatively new in late 2008 and I got my first iPhone: the lack of a wish list.

I use the Wish List feature of iTunes a lot on my computer. Because I use iTunes mainly for buying apps and checking for updates, I rely on the Wish List to save interesting apps and games to check out later. However, I’ve dropped the occasional song or movie in the Wish List too.

The iTunes Wish List is simple and effective.

Too bad it doesn’t work on iOS devices.

While there have been some rumors on dedicated wish list features coming with an iOS update, in its current state the App Store (and iTunes Store) can’t use your iCloud account to sync items you’ve added to your wish list.

Recall by Overcommitted is not a wish list replacement in the sense that it’ll provide you with a list that syncs across devices. For that, I still use (and recommend) AppShopper, which is just phenomenal when it comes to tracking app updates and price drops with push notifications. Instead, Recall is about “never forgetting iTunes recommendations again”. It provides an alternative interface for the iTunes and App Stores, allowing you to save recommendations and create reminders for them. Read more

Best MultiMarkdown Previews On iOS

As a quick follow-up to my Nebulous Notes post on MultiMarkdown macros, I decided to put together a quick representation of how various apps I have tested handle MultiMarkdown previews on iOS.

For reference, this is the text I previewed in each editor:

It’s a mix of regular Markdown (reference, inline links, bold and italics, section headers), MultiMarkdown (footnotes) and regular HTML (the centered image). I always write with this combination of syntaxes because that’s how articles end up on MacStories. The mix is also a good stress test to see how an app can handle various implementations of Markdown and HTML simultaneously.

Sakura Quick Math

I’ve always been bad at mathematics. It’s not that I don’t like the subject per se: I prefer words.

However, as they teach you in school, numbers are important. Some would argue our universe is made of numbers and mathematic relationships between their entities. Personally, I’d be fine just being able to jot down a quick addition or subtraction and having the result in my head without pulling out my iPhone’s calculator. The meaning of the universe can wait.

I think Sakura Quick Math is an interesting experiment for kids who want to improve their arithmetic skills for schools, as well as people like me who are way past high school and are often reminded that they’re terrible at calculations. Sakura Quick Math combines a clean, typography-oriented UI approach with the personal goal of getting better at stuff like additions, multiplications, divisions, and so forth.

Sakura Quick Math is perfect for students in grades 3, 4, 5 & 6 or those people who want to improve their all round mathematics ability. Multiple difficulty levels allow the app to grow with your skills. Developed in partnership with several schools, teachers and psychologists, with dedicated practice Quick Math should improve mathematics skills.

I like the app for a variety of reasons. It’s a game, but it’s also an educational tool; it reminds me of the Brain Age/Brain Training “games” that were so popular on the Nintendo DS a few years ago. Just like Brain Age, Sakura Quick Math takes advantage of the platform it runs on with a fully touch-based interaction. Through built-in handwriting recognition, the app “understands” the numbers you’re writing on screen. In my tests, I’ve found the app to be really clever at figuring out my scribbles, though it sometimes hung on “4” and “9”. However, it was just a matter of getting how the app wanted those numbers to be written (tip: don’t lift your finger off the screen).

There are various difficulty levels for five modes. The main screen allows you to pick one of these modes, disable sounds, or open the Settings to adjust the handwriting recognition method. You can also check out Game Center leaderboards if you want to feel bad about yourself.

When you’re playing, you have to be fast in writing your answer, as shorter times is what you’re going after. You can write anywhere on the screen, and you can clear your answer with a two-finger swipe if you’re not sure about it. Otherwise, the game will take a correct answer as soon as it’s entered. You can skip questions, or end games and go back to the main screen. The app has a nice selection of sound effects and it displays records on a chart that puts the focus on “getting better” rather than “beating someone else”. It’s a subtle but important difference.

I’ve found Beginner to represent an enjoyable challenge, but then again I’m bad at this kind of stuff, as I said above. You’d probably want to look at the Advanced level for the last mode, which mixes everything in a single game.

Sakura Quick Math looks good, is fun to play, and it’ll probably make my rusty brain a little less old when it comes to arithmetics. Plus, it’s only $0.99 on the App Store, so check it out if you’re looking for something different than the usual Angry Birds or Temple Run-style game.

Uniconsole: Copy & Paste Unicode Characters and Symbols

In putting together my Nebulous Notes macros, I ended up having to choose icons for the buttons that would sit on top of my keyboard. As you can see from my screenshots, I’m using specific Unicode characters that add a touch of personality to the interface. I copied those characters using Uniconsole.

Uniconsole is a very simple, do-one-thing-well $1.99 app that runs on the iPhone and iPad. It fully supports iOS 6 and the new iPhone 5 display. Uniconsole lets you copy “unconvential” Unicode characters and symbols of various kinds and alphabets. While you can find these for free on the web, Uniconsole provides a nice interface to switch between alphabets and sections, save favorites, and copy them to the iOS clipboard. You can copy single characters or multiple ones at once; on iOS, you can bring up the native share sheet by tapping and holding on the scissors icon in the text box.

There are various pages of default symbols and characters; by swiping all the way to the right, you can access sections, including:

  • Dingbats
  • Arrows
  • Shapes
  • Letters
  • Technical
  • Currency
  • Old and New Emoji
  • Mathematical

The selection is very rich, and the app is easy to navigate. There’s also a dedicated page that lets you type anything with the system keyboard, and apply a “fun filter” to your text. Filters include things like flip upside down or custom strikethrough.

Uniconsole does one thing extremely well, and while the characters and symbols it collects can be found online with a bit of research, I’ll take the convenience of a Universal app over wasting my time looking for a Unicode arrow any time. If you’re looking for this kind of functionality, $1.99 is money well spent for Uniconsole.

Faster Markdown Editing with Nebulous Notes Macros

I have written about Nebulous Notes before. Back in August, I posted an overview of my workflow with the app, plain text, and Markdown:

Combining Nebulous’ support for text substitution and cursor position macros has enabled me to achieve a powerful workflow when it comes to writing in Markdown. For instance, I can select words I want to turn into inline links, and have the app automatically wrap them between square brackets, and paste the contents of my clipboard (the link) to the right. To copy Markdown-ready links, I use my own bookmarklet. Or if I want to create a list, I can hit a button that inserts an asterisk and a space. Or again, if I need to create a text file with a format that OmniOutliner recognizes correctly, I can indent items with Nebulous’ $tab and $cursor macros.

Since then, a major 6.0 update to the app has been released, which, in my opinion, deserves another look. For the occasion, I’ve put together a few videos showing how I use the macros I have created for easier and quicker Markdown (more specifically, MultiMarkdown) formatting. The videos were recorded on a Mac using QuickTime capturing an AirPlay Mirroring session through Reflection. I have embedded them here using the video tag supported by most modern browsers (video files are encoded in MPEG-4). For Firefox users, there’s a fallback to Theora .ogv files (converted using ffmpeg2theora). I will also make my macros available for download at the end of this post. Read more

Getting Google Maps Back On iOS 6

Since the release of iOS 6, I’ve been looking for apps and services to get Google Maps functionality back on my iPhone and iPad. While not as integrated as the previous Maps app of iOS 5, I’ve settled on a combination of various tools to access Google Maps for those times when Apple Maps fail me (unfortunately, most of the time in my area).

Netbot: Tweetbot Reborn for App.net

Today, App.net gets its best iOS third-party client to date, and, unsurprisingly, it comes from Tapbots. Netbot is now available on the App Store for iPhone and iPad.

What’s not surprising isn’t simply the fact that Tapbots released an app that sets the bar higher for the competition; at first, it’s the fact that Netbot is basically Tweetbot re-engineered to work for App.net. Read more

60 Mountain Lion Tips

Published today, 60 Mountain Lion Tips is the latest entry in the MacSparky Field Guides series. Co-authored by Brett Terpstra and David Sparks, the book stands out for its clever use of iBooks 2.0 features (though a PDF version is also available) and embedded screencasts. There are 53 screencasts with 1.5 hours of video for a total of 60 tips organized in sections like Mountain Lion, Keyboard, Mail, and more.

I was able to read the iBooks version on my iPad, and, as usual, everything’s just great. I’m a big fan of David’s screencasts (see here and here for examples), and the format of this new book makes for a quick consumption that, however, doesn’t lack in depth. The tips are laid out clearly on the left side as text (assuming you’re reading in landscape mode, which lets you see more of a page), and screencasts are available as video thumbnails on the right. Both text and video are clear, concise, and to-the-point. David and Brett do the voiceover, and the quality of the videos doesn’t disappoint – they are compressed, but not too much, so they’re still pleasant to watch on the Retina display. The videos contain both voiceover and system audio, as well as on-screen tips for keyboard shortcuts and menus.

The layout of the book is clean, and, like David’s previous Field Guide, compliant with the design standards of iBooks Author. For instance, you can navigate from a page to a chapter by pinching out, you can access a dedicated page for notes and highlights, and you can watch videos inline. Similar to Push Pop Press’ old physics engine, you can also “move” videos on the screen as they play. It’s not that useful, but it’s very cool.

More importantly, 60 Mountain Lion Tips is easy to read and, in just a few hours, I actually got a lot out of it. We had our own Mountain Lion tips in our first eBook, and yet this book taught me a few OS X tricks I didn’t know about. I especially appreciated the section on third-party app tips, which many roundups usually don’t cover (we didn’t).

60 Mountain Lion Tips is only $6.99. Check out the website here for more information and a link to the separate PDF purchase.
