Google Glass needs a Personal Video Loop

Friday, May 3rd, 2013

I’ve been doing a lot of thinking about Google Glass at the moment and so far I havent seen anything to make me want to rush out and buy a pair (although I reserve judgement till I actually play with one). One of the things getting a lot of attention is the ability to record hands-free video which in my opinion is over-rated. I’m basing this on in-car video recorders (and more recently dashcams) that people have been using to record hands free video while driving for years. I have been using a variety of different setups to capture in-car video over the years and have found that while its very cool at first, it’s quite rare to go back to look at the video. Of the hundreds of hours of video I have collected, I only look at it when there is something specific I needed to check (line, traffic, best lap, etc…) or to see if the video captured something spectacular (spins, passes, accidents, etc…). In general it is quite boring to look at hours of raw video even while doing something as interesting as racing cars on track. As for making edited videos it is a long, slow and difficult process and people wont be bothered to do it once.

What Google Glass really needs is to take a suggestion from the dashcam world and record a continuous loop of video that the user can save after the event to record the important/funny/interesting thing that they just happened to see. It would be a video version of the Personal Audio Loop (paper pdf). A Personal Video Loop if you will.

Imagine being able to immediately save some cute thing thing by your kids/dogs/cats/etc… Instead of remembering to tell Glass to record, it is always recording and you can just tell it to save the last X minutes. Apart from the cute overload videos, the number of dashcam videos on Autoblog and Jalopnik are proof that even the most average people will keep seeing some interesting things. Plus the sousveillance aspect of having cloud-stored video to back up you account of events would be pretty revolutionary as well.

I know there are a bunch of legal (and power) issues around recording video like this but someone should try building it. Glass explorers – start exploring :-)

Amazing audio quality of the Nokia N900

Tuesday, July 20th, 2010

The fact that I have been using various Nokia phones and attending multiple Iron Maiden concerts (5 at last count) over the years led me to this amazing demonstration of the improving audio quality of Nokia cameraphones. While I have been a big fan of the N95 camera but I always complained about the audio quality when recording video in loud environments. This video that I recorded at the Iron Maiden show in Concord in 2008 shows how the N95 struggled with clipping and noise issues when the environment was too loud.

Now fast forward 2 years and I went to another Iron Maiden show in Concord a few weeks ago with an N900 and recorded the following video clip. In this video I am once again in the front row of the pit but am offset to the right and am in fact standing right in front of a 6 foot high speaker stack. Both video were copied off the phone and directly uploaded to Youtube with no editing of any sort.

As you can see the N900 video has much better audio quality and is actually good enough to understand the song lyrics despite the fact that I am actually standing in a noisier location. Additionally the video is in true 16:9 widescreen with fewer compression artifacts than the N95 video. It is also better at dealing with the low light levels and the background lights pointed at the screen.

I have to give kudos to Nokia for continuously improving the performance of their devices and cant wait to play with the N8 when it comes out in October.

P.S.: All the photos below were taken with my N900 at the same concert. You can also see two other videos I shot below

The ultimate mobile search experience (a.k.a Foodfinder lives)

Monday, February 9th, 2009

The folks at Yahoo oneSearch just announced the new oneSearch Shortcut application with a new auto-locate feature that determines the users location using cell-tower positioning and wi-fi triangulation. This combines with the existing voice search and oneSearch clusters to create what is in my opinion the best mobile search experience in the business (especially on Nokia S60 devices). Read on for a quick description of the user experience:

oneSearch Shortcut
The Shortcut application starts off by showing you a small text entry field on the idle-screen of you mobile phone. The text field has a small note telling you to hold down the “Call” button and speak. I think I’ll give Slumdog Millionaire a try.

oneSearch Shortcut Voice Search
Once you have said the search term the app “thinks” for a couple of seconds before showing you the search term for confirmation. Just hit the “Search” button to start the search.

Auto-located oneSearch results
Which results in a search results page that automatically determines your current location (Sunnyvale, CA in my case) using cell-tower and wi-fi beacon positioning. Additionally since oneSearch knows that “Slumdog Millionaire” refers to a movie, it automatically displays the movie information along with the showtimes from the nearest theaters. You can even use the “Buy Tickets” link to buy your tickets so you wont have to wait in line when you get to the theater. Click through on the image above to see the full search results page which includes things like the trailer, official website, movie reviews, etc…

And of course movies aren’t the only thing you can search for this way, Shortcut helps you find any local content (restaurants, stores, etc…) based on your auto-locate location, as well as regular web content. And for those of you who prefer typing it also has search assist which allows you to auto-complete your search terms. In my opinion this integrated solution that allows users to find information (local and otherwise) by just saying what they want is the ultimate mobile search experience. Get it on your Nokia S60, Blackberry or Windows Mobile phone by visiting http://mobile.yahoo.com/onesearch/shortcut.

P.S.: For those of you who remember my Foodfinder hack from YRB – yes that’s exactly what auto-locate does :-)

P.S.S.: I do work at Yahoo! but these are as usual my personal opinions and do not reflect on the views of Yahoo!

Attending Nokia Open Lab 2008

Thursday, September 4th, 2008

I am going to heading to Helsinki for Nokia Open Lab 2008 which is being organized by the folks at WOM World. While the exact program hasn’t been nailed down yet, the invite does sound interesting:

Nokia Open Lab, held in Helsinki, is an event with the aim of provoking global discussion on a mobile future.

The event is the first of its kind hosted by Nokia, where an invited set of social media participants from bloggers to forum members and everyone in between will be taking part in workshops that will focus on the future of mobile and co-creation of media.

The event’s benchmarks of learning for both the attendees and Nokia include how social interactions and technological interactivity affect us. The workshops will also focus on issues such as how everyone will utilize these new technologies and how the most benefit for all will come about.

Since it is an event for “social media participants” they have already created a wiki and a FaceBook event. It should be a fun event and I look forward to meeting the rest of the folks.

In honour of the event I have hacked together a ZoneTag action tag which will allow me to post selected ZoneTag Flickr images to my twitter stream and also set my FaceBook status. If this experiment goes well I’ll eventually open the action tag up to all ZoneTag users.

Nokia N810 Tablet Review

Tuesday, August 19th, 2008

I am a big fan of the Nokia N800 and use it quite frequently as a video player and RSS reader when I am on the go. The addition of a slide-out keyboard for the Nokia N810 made it a very desirable device and I was very excited when the folks at WOM World lent me a test device to play with for a few weeks. As luck would have it, I got the device just before a short trip to Atlanta and so I decided to give the N810 a real work out to see if it could replace my laptop. So for the first time in years I left my laptop at home for a trip and exclusively used the N810 (paired with my 3G N95) for all my computing needs.

For those of you who are not familiar with the N810 it is basically an updated N800 with a built-in, slide-out keyboard. The other major differences were a fixed front facing camera (as opposed to the rotating one on the N800), built-in GPS, 2GB internal storage and a single miniSD slot (instead of the 2 regular SD slots). The buttons on the front have all been moved either into the slide or the top of the device making it look and more importantly feel a lot smaller than the N800 even though they have the same size screen.

In general the N810 performed very much like my N800 – the screen is very clear and the battery life is pretty good. The audio is decent enough and it is able to play most video format right out of the box. The GPS chip had adequate recption though I did have issues pre-downloading maptile data – it took multiple hours to download the eastern US (~700 MB) and in the end it failed sometime during the process. The built in browser was pretty decent and I was able to visit all of my usual websites and do all my email with no issues. It came very close to being a laptop except for two deal breakers which were unfortunately both associated with the new slide-out keyboard:

First off the keyboard is really hard to use. It requires a little too much pressure to register a key press and even worse it does not give adequate feedback when a key is pressed. This is especially difficult in central keys like R, T, G, etc… I found that I would have to press the key and then immediately look at the screen to see if the press had registered. Plus since you are only typing with your thumbs it means that touch typing is not an option and you will have to keep looking from the keyboard to the screen. However I am willing to give Nokia the benefit of the doubt on this one – it is possible that the device I got was bit defective due to heavy use (it had been used by other people in the WOM program) though I would still hope that a device like this should be able to go through heavy usage without issues.

The second and much more serious problem is the interaction between the the keyboard and the touchscreen. The screen is small enough that its really not practical to tap on web links with your fingers. This means that most navigation is done using the stylus which is similar to the N800 and works pretty well here as well. Similarly the keyboard works quite well (assuming your keyboard works better than mine) when you need to enter text. The real issue is when you have to do something that involves both navigation and text – it is extremely difficult to type on the keyboard while still holding the stylus in your fingers. The ideal position for typing on the device is to have both index fingers on the top edge of the device with both middle finger supporting the device from below – this leaves your thumbs free to type. However this position also means that the gap between your index and middle fingers is too large too easily grip the extremely thin stylus. You can try and wedge it against the side of the device itself but that puts pressure on your fingers which will start hurting pretty soon. You could try putting the stylus down down/away every time you type but that will become extremely tiresome. And finally the change in hand grip from one-handed(to point) to two handed(to type) every few minutes is quite annoying too. While the keyboard and stylus are good at their individual tasks they are just not designed to be used together which means that the N810 is actually harder to use that my original N800 with its stylus operated soft keyboard.

The touch screen is a nice interface for web browsing but as more and more information moves into the cloud, a tablet-class device must have adequate (and relatively seamless) text entry mechanisms as well. What Nokia really needs is a secondary (or in this case tertiary) input method such the blackberry scroll-wheels and trackballs that allow the users to use a mouse-like functionality without changing their grip on the device. The touch screen will continue to serve as the browsing interface but users will also be able to go into the text entry mode which allows them to enter text and move around the page without having to change their grip on the device. If Nokia is able to get this right the N810 will truly become a laptop replacement for short trips and vacations. However in its current state I would recommend that you go for the N800 instead – it is both cheaper and the soft keyboard is much easier to use.
