Smarter Cities

2 Replies Jonny Hankins

Following on from my post last week about Apps and Christopher’s post about smart skies on Tuesday of this week I would like to introduce smart cities. Harvard University graduate School of Design run a course that they describe as Urban Cybernetics, called in fact Smart Cities. It is taught by Nashid Nabian, and the aim is to design urban projects that use technology to improve urban life.

The final projects are available to browse online through the course website, and many are very interesting. Cameras and sensors are some of the tools of the trade, used to measure pedestrian or cyclist use of the city, to improve traffic flow or better understand the mechanics of the city from a host of other points of view.

One of my favourite projects is called The Listening City and was written by Carolina Soto within the Real-time Cities course in autumn 2011 as part of the Responsive Environments and Artifacts Lab. Her project involves the use of QR codes that can be scanned using a smartphone. The codes are attached to street furniture, dustbins and all types of functional objects for the running of the city. If a passer by wants to report a problem with any of the objects, they just have to scan it with their smartphone.

Once scanned, the user is lead to a website where they complete a questionnaire related to the functionality of the object (in the case of a dustbin if it is full or empty etc, or for a pedestrian crossing light if it works or not).

As the position of each code is known the problem can then be signaled on an interactive map, with the data centrally collected so that it can be analyzed and patterns discovered that may help in improving services.

Take a further look and watch her slide presentation here.

Design and designers affect almost everything in our lives, and working towards improving city life through technology seems like a great idea to me. We are talking about real life improvement that can be seen and measured, information about which bins fill and overflow first is important, the city can be redesigned to confront the problems caused. It might also create solidarity within the residents, more participation in civic life and resolve some of the niggly issues that urban living throws up.

Citizens connect!

This week I would like to take a look at a couple of technological and social systems that use Apps and are designed to improve urban living in cities. If you have ever asked yourself how technology can improve our lives then the following might be of interest to you.

The first thing I would like to look at is called Citizens Connect, a system that operates in Boston in the USA (where I currently live). According to the website “Citizens Connect enables real-time collaboration with citizens, “deputizing” mobile users to become the city’s eyes and ears. Citizens report potholes, graffiti, and other issues from anywhere in the city using their mobile phone”

And this is how it works, and it is a simple system if you have a reasonably good mobile phone. While walking or driving through the city you see something that you feel should be reported to the City Council, an abandoned car, vomit on the pavement, water gushing from a hole in the road, cat stuck up a tree, that kind of thing. You take a photo of it, upload it on the City of Boston website, they show it on a public map and (hopefully) send somebody out to fix the problem.

I personally believe that a person is much more likely to report something if they can take a photo and send it off in real time than if they have to go home, look up a phone number and make a call. Could this be a fist step in making the citizen and the state more communicative and more responsible?

The City of Boston also offers another App called Street Bump. This is even simpler to use, you download it into your phone and it monitors your movement as you drive round the city. When you near a hole in the road you slow down, as does everyone else passing that spot, and this information is used to determine the quality of the road surface.

If you think your local council should try such a scheme, you can direct them towards Click Fix, a commercial system that is currently on sale and operated by several cities and other organizations. This is not a recommendation however, but their work does look very interesting.

Next week I will continue this theme with a look at an interesting university course all about “Urban Cybernetics” that is run at Harvard University. Some of the projects may offer great things for the future.

Are smartphone battery life improvements on the way?

We all want a little more power. Smartphone manufacturers have catered to this desire, as they’ve continually pumped out increasingly powerful devices.

This year we’re seeing many quad-core devices with 1.5GHz processors, powered by 4G LTE networks, and with vibrant high-resolution displays. Yet these high-powered devices are about to hit a wall if we don’t see some critical changes in battery efficiency. Without adequate battery life, even the most powerful smartphone is useless.

Thankfully, there are a few reasons to believe that we’ll see appropriate improvements in the near future. Here are three reasons why we will see smartphone battery life improve in the coming months and years. It will be a great boon to consumers, who will be able to use their phones heavily for longer.

1. Consumer disappointment

Earlier this year, Motorola made something of a bold move. In a world of thinning smartphones, it actually released, and heavily marketed, a smartphone that is considerably thicker than many of its other models.

This only worked, however, because with the increased thickness came greater battery life. By most reasonable tests, the Droid RAZR MAXX lasts nearly twice as long on a single battery charge than most of its competitors.

The rationale behind this marketing campaign was simple. People love their smartphones, but get frustrated when they can’t last on a single charge throughout a day. Again, a powerless smartphone is a useless smartphone.

You can stuff all the features in the world under the hood of a phone, but if people need to constantly recharge in order to use those features there’s not a lot to be gained. Improved battery life will simply become a necessity that manufacturers cannot ignore.

2. Changing energy trends

The way we consume energy is always changing. The recent technology revolution will change it yet again. Most of our modern computing devices employ DC power, but our wall sockets deliver AC power. That leads to a few inefficiencies, since the difference requires a converter of sorts, whether that’s in the device or in the power source itself. We might see that change in short order.

As Technology Review notes, there is a growing demand for DC current source. It is possible that we could see power companies start to deliver DC power to our outlets in the next few decades, which should make the whole charging and powering process more efficient. The lack of conversion could make that big a difference.

Yet, given our consume-driven culture, it probably won’t make as much of a difference as my next point.

3. Apple’s doing it

It seems that whatever Apple does, other companies copy. Apple has long been an iconic force in technology, and their iPad and iPhone empire has helped solidify its spot at the top.

What they do with the iPhone 5 could again change the smartphone industry. As GigaOM’s Kevin Tofel notes, Apple could focus on battery life with the new iPhone, rather than creating another thinner model. He cites the increased battery capacity of the new iPad, which seems reasonable enough.

Improving smartphone batteriesIf Apple does indeed create a thicker smartphone that focuses on battery life, others will be pressed to follow suit. Remember, Apple essentially tells consumers what they want. Perhaps they wanted it previously – and plenty of customers have demanded better battery life from smartphones – but Apple does have the definitive word.

It’s hard to explain, but it’s clearly the case based on how the smartphone industry has developed. If Apple goes for battery life, we can expect others to jump on the bandwagon too.

Battery life has become a pressing issue for the future of smartphones. Manufacturers have created devices that are as powerful as full-sized computers of recent memory. Now they need adequate power for them.

Since a powerless smartphone is a useless smartphone, expect companies to jump on the better-battery bandwagon soon enough. Apple could get things kick-started this year. Things will likely develop rapidly from there.
