Again with headache, after a few hours of working in train, it comes apparent that even with hi-def, retina displays, the non-ergonomic posture and other troubles of working with laptops in cramped surroundings of mobile work are not going away.
There are probably several solutions to this particular challenge, but here is one idea: how about rather than insisting on staring at a laptop, having something like the recent Intel “PC on a stick”, plus a battery pack/power brick, coupled with a best-of-line wearable display? As those things are getting lighter and the projected displays sharper, and some of them also go for semi-transparent, see-through technology, there appears to be a true alternative future for wearable computing that consists of multiple devices plugged together, in a modular fashion. One problem with thin-and-light laptops is, for example, that their pursuit for paper-thin form factor compromises the keyboard. With a PC stick in your pocket and a see-through-display on your eyes, you also could have a really good, wireless keyboard and mouse connected as the input devices, and keep looking naturally ahead of you, with a large and sharp virtual display hanging in the air, at the optimal position and distance to save your eyes and neck from extra strain.
The current generation is probably not yet ready for the job, but here are some pointers for those who are interested to see where we are right now:
If you were a techie nerd in the 80s, you might have used a Casio Databank wristwatch: a bulky device that had a small LCD screen, capable of acting as a calculator, address book, as well as a simple gaming device, while also providing advanced clock features. Those watches were (and still do) dividing user opinions, some enjoying their technically advanced, engineer-oriented pleasures, some staying as far as possible from such gadgets. With today’s focus on “smart watches” and “fitness bands”, such bulky appendices may be making a return to thousands of wrists this Christmas.
Another way of looking at these things is to consider them as the coming of the “wristwatch computer”, or manifestations of wearable, pervasive or ubiquitous computing, depending on the more general concept to adopt. As such small, “smart things” start to network and communicate with each other, they are also parts of “Internet of Things”, or “Web of Things” developments. The overall promise is of better services, which are more contextually aware, that provide information and interaction affordances in more convenient ways than the old, “PC-centric” computing paradigm has allowed. Such technologies are on the one hand inherently personal, as they connect with a trusted device (typically your mobile phone), which also may include your calendars, contact information, various social media accounts and other personalization information. On the other, they tap into new types of sensors, location-aware services and proximity beacons to provide novel services and experiences.
The futuristic promises are great, but the reality is still in the making. The current generation of smartwatches are limited in many ways, including unwieldy form factor, limited functionalities, occasional bugs, and typically rather short battery lives. The promise is nevertheless there, and many people appear to be drawn to experiment with such devices on the basis of two key functionalities: accessing smartphone alerts and information from a wristwatch, and for fitness or health information captured by the smartwatch sensors. The more advanced functionalities such as universal NFC payments, or location-based games are still waiting in the future.
My recent experiences on smartwatches are based on setting up the Samsung Galaxy Gear S (apparently a good exercise for your faculties also while lying down with a nasty flu in bed). There are multiple hoops that an early adopter seems to need to hop through: for example, you need to have a particular type of Samsung smartphone in order to use it. Having a custom rom in the phone was also a no-go, so in my case for example, I first had to uninstall the Cyanogenmod 11 I had been using in my Galaxy S4, wipe the phone, install the stock Samsung TouchWiz rom, and after that to proceed to reinstall all my applications, set up all the user accounts and re-authenticate e.g. all two-factor authentication-enabled services – a process that can easily take several hours, and is probably btw enough to turn away few interested testers.
After inserting a nano-SIM card (this device can also double as a stand-alone gsm phone), and charging the Gear S, it is time to install the necessary Galaxy Gear Manager application into Galaxy S4 from Galaxy Store (this is not available from the Google Play store, even if it is an Android app), which makes it possible to install applications and customize the Gear S. The limited selection of Gear apps is one indication of the somewhat problematic, fragmented character of current wearable ecosystems. Rather than supporting Android Wear, the Google ecosystem for wearables, Gear S is based on Tizen, a different Linux based mobile OS, developed by an association of companies, led by Samsung. Next year, the Apple Watch will arrive, opening up yet another key competing ecosystem. Getting support of e.g. your Google Maps favourites and navigation to Gear S soon does not seem likely in this competitive situation, and if you are having your calendar in Microsoft Exchange 365 server, or iCloud, for example, you first need to figure out how to get that information synchronized to the smartphone that acts as the “base station” for the particular smart device you got your eyes on. Everyone is obviously adopting a gold rush tactic, and try to grab as much land in the emerging user base as possible, trying to lock the users to their own, proprietary wearable ecosystem. From the user perspective, the situation is not optimal.
Thus, while it is nice to see e.g. movement information automatically recorded by Gear S in its S Health app, I am already a user of the leading Runkeeper service, and there is no Runkeeper app in Galaxy Gear S, nor is there a way to integrate S Health data with Runkeeper that I know of. Another handy feature would be to have the daily navigational guidance right at your wrist, when you need it. I have already long adopted the habit of including location information to all my important calendar events, so that when I am on the run, one click on the smartphone calendar will automatically open maps, with navigation, helping to choose whether to walk, pick up public transport or a taxi, which is particularly handy in a foreign country or city. Google Maps is particularly good with the public transportation schedule integration, but also Here Maps (ex-Nokia) is pretty decent in this area, at least here in Finland. Gear S does not support Google Maps/navigation, but Here Maps is supported (in “Beta”). It features turn-by-turn navigation, which appears to work and is a very good service. However, while Gear S has a bright and sharp two-inch AMOLED touch screen, which makes it into a very large wristwatch, it is still painful to use for typing in an address, with the tiny QWERTY keys. It is possible to use “Send to Gear” action from the smartphone version of Here Maps, but this seems to work only for beaming the walking instructions, and the entire operation also somewhat negates what is the key idea of wearables – of not needing to dig up the smartphone in a busy situation, with the smartwatch ready in the wrist. Another way around this would be to use “S Voice” input in Gear, but as the Finnish language is not supported, there is currently no way to just speak the local address to the Gear S. While you can get your meetings’ location information displayed in Gear S by including it into the default calendar in your supported Galaxy smartphone, it does no good trying to tap that address line in Gear S, as it is not currently linked to any navigation action.
It finally boils down to practical things such as battery life and form factor of the device, as well as language and application/service support, which of the emerging smartwatches will be a real success among the users. Based on very limited, first experiences, Galaxy Gear S is a good attempt, but finally a borderline case. The plastic-covered wrist computer is so large that at least my skin gets a bit sweaty and irritated after wearing it for several hours; stylistically, the size alone might be a complete turn-off for many potential users. Getting the notifications from text messages, emails (I opted out of those), Facebook or Twitter messages, or occasional Google Now update into the wrist display are sometimes truly useful alarms, but often distracting interferences. If you already have a tendency to lose your concentration easily, the current wearables might not be for you. On the other hand, if your work life relies on following and responding to the flow of various messages and communications and calendar events quickly and efficiently, you might consider one. I have not yet used actively Gear S for a full working day, but I suspect it should make it through a day even with the clock display turned on (the default behaviour is that it is turned off to save battery, and reacts to the movement of your rising hand by lighting up – which it often did, but also failed to do often enough to become really irritating to me at least).
Our research group has been doing studies into the future user cultures of emerging game and media technologies for years, and the ethics and rationale of design is something that we try to pay special attention with. Wearable smart technology holds promise e.g. in health, social and gamification applications of various kinds, potentially communicating the social presence of our important people literally to “our skin” in real time. It can also be used to remind us to balance our lives better, or to help us achieve our important goals by supportive messages or incentives. Gear S did bring up the S Health Pedometer display every now and then while I was writing this thing, reminding me about my physical inactivity and encouraging me to get up and moving. In my case, that was not probably the most efficient rhetoric Samsung could have adopted, but maybe there will be also other, more playful and less efficiency-oriented apps available in the future. And if not in Galaxy Gear platform, then those interesting experiments will be arriving in some other. (There was one, exploration oriented “POI Nearby” style Gear app I could find, but I could not get it to understand Finnish language or place names, either.) In any case, the door for real-world pervasive computing and play applications is now starting to open.
Today I had a chance to do a very quick test of Google Glass in local PC/tech store. The situation was hardly optimal for any real user testing, but at least this was a possibility to try on this coveted/hated device. Despite its largish frame, the eyewear is actually rather light and easy to carry. The screen (when you finally get it in your field of vision, it requires some adjustment first) is bright and sharp enough and seems to float up there, few virtual meters away. My main frustration was with the voice control: I kept on repeating “Ok Glass”, but at least this model requires that you first activate the specs through the touchpad in the right side, navigate into the correct menu mode, which displays the time of clock and the text “Ok Glass”, and it is only after this when you can give voice commands (e.g. “take photo”, “record video”, “google University of Tampere” – which actually produced wikipedia entry for “University of Tampa” – close enough…) This is not good, and I hope this was only a feature of some out-of-date firmware (?) Otherwise, I cannot see it as very convenient to use your hand to flip through the menus (displayed in a tiny, semi-transparent floating screen) in order to get into mode where you can “naturally” enter commands. Also, the voice output from Glass was at such low level that it was almost impossible to hear anything at the noisy store environment.
Ok, Glass. Interesting, but we will have a closer look again at some future event.
