			<content:encoded><![CDATA[<p>I took a look at the new iPod shuffle today and I was dismayed by Apple&#8217;s continued development of the &#8220;intuitive&#8221; control system.  To help people use their products, Apple actually has to have a <a href="http://support.apple.com/kb/HT3458" target="_blank">website devoted to instructions</a>.</p>
<div id="attachment_385" class="wp-caption aligncenter" style="width: 460px"><img src="http://www.huginn.com/knuth/blog/wp-content/uploads/2009/03/ipod-shuffle.jpg" alt="The ipod shuffle (3rd gen) requires a table of instructions" title="ipod-shuffle" width="450" height="438" class="size-full wp-image-385" /><p class="wp-caption-text">The ipod shuffle (3rd gen) requires a table of instructions</p></div>
<p>These instructions include</p>
<p><strong>Play:</strong> click the center button once (<em>status light blinks green once</em>)</p>
<p><strong>Fast-Forward:</strong> double-click an hold the center button (<em>status light blinks green once</em>)</p>
<p><strong>Rewind:</strong> triple-click and hold the center button (<em>status light blinks green once</em>)</p>
<p><strong>Hear song title and artist names:</strong> Click and hold the Center button (<em>status light blinks green once</em>)</p>
<p><strong>Go to the next track:</strong> Double-click the Center button (<em>status light blinks green once</em>)</p>
<p>This reminds me of the combination of buttons I had to press to perform that triple roundhouse kick in Nintendo!  And that all informative status light!  Thank goodness they thought to put that in there, otherwise who would ever know that the ipod shuffle was getting your commands correct.</p>
<p>The problem is that to make these things slick and sleek Apple needs to minimize the number of controls on the device.  This puts the burden on the user to remember precisely what pattern of button presses and holds will give the desired result.  Its unfortunate that Apple couldn&#8217;t at least add some extra LEDs so that the status light actually conveyed meaningful information.</p>
<p>I find this a disturbing trend in consumer electronics resulting in devices that work like that darn overhead ceiling fan.  You are never sure how many times you need to pull on that string to get the thing to stop.  Or it reminds me of the crappy little alarm clocks where you have to press two buttons in some crazy pattern to set the alarm.  I think most people have at some point in their lives overslept because of this &#8220;feature&#8221;.</p>
<p>A good friend of mine Asaf Degani who is a NASA research scientist wrote a book called <a href="http://www.amazon.com/gp/product/031229574X?ie=UTF8&#038;tag=onlicort-20&#038;linkCode=as2&#038;camp=1789&#038;creative=9325&#038;creativeASIN=031229574X">Taming HAL: Designing Interfaces Beyond 2001</a><img src="http://www.assoc-amazon.com/e/ir?t=onlicort-20&#038;l=as2&#038;o=1&#038;a=031229574X" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" /> where he examines the design of effective user interfaces.  I should find out what he thinks of Apple&#8217;s interfaces.</p>
<p>Me? I disapprove.</p>

			<content:encoded><![CDATA[<p>Looking back, I am surprised at how electronics has quietly advanced to the point where we can buy small programmable computers on chips for a dollar or two.  These are microcontrollers of course, and in my lab we are working on programming them to handle the tedious tasks in our robotics projects.</p>
<p>At <a href="http://www.makezine.com/">makezine.com</a>, I stumbled on this gem of a book titled &#8220;<a href="http://www.amazon.com/gp/product/0596510519?ie=UTF8&amp;tag=onlicort-20&amp;linkCode=as2&amp;camp=1789&amp;creative=9325&amp;creativeASIN=0596510519">Making Things Talk</a><img border="0" width="1" src="http://www.assoc-amazon.com/e/ir?t=onlicort-20&amp;l=as2&amp;o=1&amp;a=0596510519" height="1" style="margin: 0px; border: medium none" />&#8221;</p>
<p><a href="http://www.amazon.com/gp/product/0596510519?ie=UTF8&amp;tag=onlicort-20&amp;linkCode=as2&amp;camp=1789&amp;creative=9325&amp;creativeASIN=0596510519"><img border="0" width="131" src="pics/31p83T2bAvL__AA_SL160_.jpg" height="160" /></a><img border="0" width="1" src="pics/31p83T2bAvL__AA_SL160_.jpg" height="1" /><img border="0" width="1" src="http://www.assoc-amazon.com/e/ir?t=onlicort-20&amp;l=as2&amp;o=1&amp;a=0596510519" height="1" style="margin: 0px; border: medium none" /></p>
<p>It is packed with 26 electronics projects that involve getting these tiny computers to talk to each other and the internet over both wired and wireless connections.  I have ordered all the requisite parts, and when purchased, they amount to around $280.  I am looking forward to summer vacation when I get to go through each of these projects one-by-one:</p>
<ol>
<li>Making a computer &#8220;mouse&#8221; out of a stuffed animal monkey and flex sensors.</li>
<li>Making the monkey wireless</li>
<li>Negotiating in Bluetooth with the BlueSMiRF module</li>
<li>Setting up a networked webcam</li>
<li>Connecting a microcontroller to the internet <em>without</em> a computer</li>
<li>Networked Air Quality Meter</li>
<li>Networked Games</li>
<li>Infrared Communication</li>
<li>Radio Communication</li>
<li>Duplex Radio Communication</li>
<li>Bluetooth Communication</li>
<li>Broadcasting Messaging</li>
<li>Directed Messaging</li>
<li>Infrared Rangefinding</li>
<li>Ultrasonic Rangefinding</li>
<li>Reading Signal Strength with XBee Radios</li>
<li>Reading Signal Strength with Bluetooth Radios</li>
<li>Reading the GPS Serial Protocol</li>
<li>Heading with a Digital Compass</li>
<li>Attitude with an Accelerometer</li>
<li>Color Recognition with a Webcam</li>
<li>2D Barcode Recognition with a Webcam</li>
<li>Reading RFID Tags</li>
<li>RFID and Home Automation</li>
<li>IP Geocoding</li>
<li>Email from RFID</li>
</ol>
<p>OK, I wont be making each of these.  I will get an idea halfway through and take off and work on that.  But it should be fun!</p>
