- Cool new tech, especially for mobile, detecting gesture movements from the changes they make to ambient wireless signals, uses a fraction of the power of other techniques (  )
- Also for mobile: "The big trick here is ... two [camera] lenses with two different focal lengths. One lens is wide-angle, while the other is at 3x zoom ... magnify more distant subjects ... improved low-light performance ... noise is reduced ... just as we would if we had one big imaging sensor instead of two little ones ... [and] depth analysis allows ... [auto] blurring out of backgrounds in portrait shots, quicker autofocus, and augmented reality." ()

- Shouldn't wearable computing let you be super human?
Wearable computing so far seems to be going after mimicking a tablet, but I wonder if the real success will be in augmented perception.
Current smartwatches are clumsy. They require an impossible tradeoff between having enough space for a touchscreen and not having a brick on your wrist. The early prototypes of smart glasses like Google Glass are similar, focusing on screens floating in front of your vision and existing smartphone features like recording video and taking pictures, but having difficulty cleanly handling input and the tasks you would use a smartphone or a tablet for. Some of this may be solvable with sufficiently perfect voice and gesture recognition, but that remains impossible with any tech that looks likely to be available in the next few years.
What no one seems to be asking is, do people really want a tablet on their wrist or tablet-like screen floating in front of their vision when they already have a smartphone in their pocket? Why would they want something they wear that is just like the smartphone they already have?
But what if you could put on a pair of normal-looking glasses (or contacts) and insert a small device into an ear, and then suddenly you are subtly superhuman?
I bet a lot of people would like to be able to see in infrared, have telescopic and microscopic vision, and be able to hear outside of the normal range of frequencies and volumes. I bet people would like to be able to see microexpressions, pupil dilation, skin flushes, and pulse rate changes easily. I bet people would enjoy small informational hints when they walk around like being reminded of names and who people are when they are in meetings or important road or directional cues brightened and enhanced.
From a tech perspective, this avoids a lot of the hard I/O problems plaguing the UX on current attempts at smartwatches and on Google Glass. You don't need a large touchscreen on your wrist. You don't need to type. You don't need perfect voice and gesture recognition to make this work. Augmented perception may be closer to achievable with what we already have: tiny HD cameras, virtual displays, and access to computation. And it provides something useful that we don't already have. Shouldn't augmented perception be the goal of wearable computing?
Tablets are pretty good at being tablets. And smartphones are pretty good at being smartphones. Wearable computing, like glasses and watches, shouldn't be mimicking what's already out there. They should let us do something new, something we cannot currently do.

- Game Maven: Learn to code by writing games
I just launched Game Maven from Crunchzilla. It’s a new interactive tutorial -- part of the series that includes Code Monster and Code Maven -- that is a step-by-step walkthrough of writing the code for three casual video games.
The games themselves are really fun. One is a simple vaguely Asteroids-like base defense game. The second is a sort of Angry Birds-like cannon game complete with physics and particle system effects. The third is a platformer in the spirit of Mario Bros with auto-generated infinite levels.
Game Maven is an interactive tutorial using live code. Players learn step-by-step how to build each game, getting a chance to customize and play with the games as they build them. Game Maven is an immersive educational experience with a focus on action over explanation. Players build right away with code, learning about coding by coding. Be brave, make mistakes, try things, and see what happens.
Game Maven assumes some programming experience and an interest in writing games. It’s for adults and older teens (age 16+). It’s designed for a variety of motivation levels, from those that just click through the lessons and skip most of the work, to those that do every lesson, understand every line of code, and spend hours customizing the games, everyone learns from the experience.
If you have a teenager interested in coding and writing games, please let them know about Game Maven. Please tell your friends with teenagers about Game Maven. If you want to play with writing games yourself, go give it a try. And please let me know what you think!
