GoPro Session a new option for Quadcopters

By | General | No Comments

The new GoPro session camera weighs only 74g or 2.6 ounces. Initially this does seem all that much lighter than the original 88g weight of the likes of the Hero 3 series. However a crucial factor is the case that is required for mounting which for the gopro Hero 3 increases the overall weight to 152g. Interestingly on the gopro site there is only one weight listed for the GoPro Session rather than the camera and camera housed for the other cameras. If this is the case then it will mean that there is a saving of up to 78g a healthy 52%.

So when would this make a difference to drones? I think that if you are making a drone specifically for the purpose of filming the Hero 4 will be better suited because of the quality of image. However with the racing drones of the  250 class the GoPro Session is ideal shedding weight which makes a massive difference.

Myo and Chrome … changing, opening and closing tabs with muscle gesture detection

By | Internet of Things, Myo | No Comments

myo_thalmic_labs_chromeTo get a better understanding of how to write scripts for the MYO I wanted to use the MYO to control Chrome. Here is what I set for the gestures:

  • Wave Out – Move to next tab
  • Wave In – Move to previous tab
  • Spread fingers – create new tab
  • Fist – close current tab

I also wanted to share this with everyone so feel free to download and use. chromecontrol.lua

Myo muscle sensing armband

By | Internet of Things, iPhone, Myo, Unity | No Comments

Myo Thalmi

I have been looking forward to this device ever since it popup up as an alternative method to hand tracking. It works by analysing the electrical impulses going through your arm to understand the gestures that you hand and wrist are doing and combining this with an IMU to track where your arm is. It connects via bluetooth and there are Windows, Mac, Unity3d, iOS and Android SDKs to work with. It makes quite a few promises of what can be achieved I cannot wait to get started with it.

Wearable technology the next frontier… brain reading with the InterAxon Muse headset

By | Muse | No Comments


After backing Muse on Indiegogo I received my brain sensing wearable technology headset. Brain sensing! It doesn’t understand what you are thinking about but it more provides an understanding of the activity of your brain. In the box there is the headset, micro usb cable to charge the headset, a read me book and a legal document.

Model Cluster Structure Sensor Capture, Storing, Sharing and Effects

By | Augmented Reality, iPad | No Comments


In the pursuit of new technologies I backed the sensor from Occipital Inc on Kickstarter. Being one of the first 200 hundred devices I got to grips with the device and think that it is a great device and really can allow your applications to reach out into the real world.

15 Useful Image filtering, processing, OCR, utilities and helper libraries / frameworks for iOS iPhone and iPad development

By | General, iPad, iPhone, OpenCV | No Comments

This is a list of iOS image filtering, processing, OCR, utilities and helper libraries and frameworks that I have come across for iPhone and iPad development and thought that they may be useful in one places:

1. GPU Image

By Brad Larson, GPUImage is a fantastic fast processing library to apply gpu accelerated filters to both live camera feed, movies or stills. It works on iOS 4 and above. It includes a range of filters such as Sepia, Grayscale, Blur but you can write your own easily.


2. Core Image

This is an apple framework available from iOS 5. It leverages the GPU and you don’t need to know details of OpenGL, OpenGL ES.

Documentation: Apple Core Image Docs

Feature extractor and descriptor OpenCV performance on iOS iPad and iPhones

By | iPad, iPhone, OpenCV, Software | No Comments

I came across an article demonstrating the performance of the feature extraction and descriptor, which is useful when building opencv on iOS as it shows how the performance of your application will change across all of the devices. It compares ORB, BRISK, FREAK (using GoodFeaturesToTrack), FAST, BRIEF (using GoodFeaturesToTrack), SIFT and SURF. Feature And Descriptor Performance opencv Continue reading “Feature extractor and descriptor OpenCV performance on iOS iPad and iPhones” »

SAP DCode 2014 Tec119 How to Change the World Augmented and Virtual Reality in Enterprise

Presentation at SAP Dcode 2014 AR and VR for Enterprise. How to change the World?

By | General, Oculus Rift, SAP, SAP HANA, SAP HANA Cloud, Unity | No Comments

SAP DCode 2014 Tec119 How to Change the World Augmented and Virtual Reality in Enterprise I am giving a presentation at SAP Dcode (originally teched) 2014 on the following topic:

AR and VR How to change the world?

How can augmented reality and virtual reality make a difference? What technologies are available today and coming? Find out from three-time DemoJam winners who pioneered smart glasses AR connected to SAP HANA. This extends going beyond 2D interfaces using 3D, augmented reality, virtual reality, and more connected to SAP providing next-generation applications.

I look forward to seeing you there. Check out the session here.
