Hard hard user interfaces.

Started as someone doing ActionScript in Macromedia Flash I got into Human-Computer-Interaction after watching Jeff's Hann's multi-touch work. That's the power of a really cool demo that inspired the birth of NUIGroup community which spawned 1000s of makers all around the world making their own projector camera multitouch systems. All of it became mainstream once Apple released the iPhone to the world, and also gave birth to my interest in human-centered engineering. I spent some 10 years after that playing with sensors, haptics, and gestural interfaces through multiple input modalities but nothing stuck as much as multi-touch did. Thanks to Apple's execution. Everyone's phone/tablet interaction is default multitouch. (unless you have a visual impairment). Primsense evolved into Kinect, then came Wiimote, Leap but nothing stuck.  for speech, it was Amazon's Alexa. Latest news , that its going to lose Amazon 10B.  Like I am writing this post through my keyboard a...

Done ! the FTIR acrylic frame

-
After much haggling and bargaining we got our 6 mm thick plexi-glass sheet, after manual polishing and shining the task at hand was to fit in the LED's inside so as to facilitate the FTIR
( Frustrated Total Internal Reflection) , this principle behind the project.

Since Sudhanshu and Rahul were most affluent in Electronics and Architecture, we moved to R.S. Electronics, owned by Rahul's father "Mr. ... " so as to get our LED's fixed in the acrylic frame. After putting in 15 hours we could get the IR LEDs fixed into the wooden frame. Here are some images of Infrared glowing acrylic frame from a night-vision camera.















Along that, I modified the Microsoft Lifecam VX1000 ( removing the Infrared Filter, putting up a IR bandpass filter).
That's how it looked before and after
















Coming up's how we obtained our neat and sweet blobs :-)

    hello, may I know where did you get the bandpass filter for vx-1000? I've been searching high and low for it but couldn't find any. Please email me dylien255@hotmail.com

    Thanks in advance.:)

    for the Bandpass you need to use a Overexposed undeveloped photography film. That's the workaround that we used and worked perfectly for us.

NZM-SEC Superfast express that took my '35 hours'

I usually cover my long distance travels by air- for it saves time, and is less tiring (and was affordable in the past).  Call it naivety or my callous attitude, but I completely forgot the fact that its hard to fetch a cheap ticket when your travel plans are made just a day in advance. Owing to recent price inflations and my last minute plans I decided to cover my return journey from Delhi to Hyderabad via train. The decision was taken a day before I wanted to return, i.e. 19th May, high time when there are summer holidays in India. The night before I stood in the train line, with my father and brother, to fetch tatkal tickets. The process is hard- the HTTP fetch request by IRCTC works like a lucky draw). Hence, my attempt ended up futile.  So I decided I'll jump on the train, painful decision-no tickets, no seats, just that. The beginning. I left my home at 7PM. Reached Kshitij's place. Had dinner there- met Surbhi, Sonia aunty and uncle there. Kshitij's mo...

Ideas

Multiple ideas I was thinking about that could be used to improve people's lives- make new experiences happen, and tap into the unknown -- Sound Glasses. The user wears the glass and looks at a painting. A large painting. And the system gives audio feedback on the parts highlighted based on an audio command 'Tell me more'. Technology: Pre-calibrated system. Easy Or multiple paintings and it starts speaking about what you're looking at. Audio annotations. Leave specific audio snippets at places. ' User looks at certain objects 'drops' audio snippets' Later. Someone else could visit and listen to them. e.g. 'please clean this wall' 'this is Fluid interfaces demo area, find a student to help you out' 'This is where Media Lab started its first group' Audio post-its Inkharvester- presented as a hack(goes to indie inventors)- discussed with Harshit. http://penn.m...

discordant yet musical whistles

-
My house in Delhi has a guard that walks around and whistles all night to keep the thieves away. I am still amused by the fact how the entire street comes together and contributes and hires the guard, instead of complaining and waiting for the Govt. to solve their issues, which is slow as heck. Its like a citizen contributed and distributed parallel police with evolving protocol, when the systems don't work well. Atleast it keeps the societal interaction intact and neighbors talk, which i believe is a good thing- communities being vocal about their issues. writing this at 3AM while everyone sleeps and guard is awake.
