Presented at CHI 2012, Touché is a capacitive system for pervasive, continuous sensing. Among other amazing capabilities, it can accurately sense gestures a user makes on his own body. “It is conceivable that one day mobile devices could have no screens or buttons, and rely exclusively on the body as the input surface.” Touché.

Noticing that many of the same sensors, silicon, and batteries used in smartphones are being used to create smarter artificial limbs, Fast Company draws the conclusion that the market for smartphones is driving technology development useful for bionics. While interesting enough, the article doesn’t continue to the next logical and far more interesting possibility: that phones themselves are becoming parts of our bodies. To what extent are smartphones already bionic organs, and how could we tell if they were? I’m actively researching design in this area – stay tuned for more about the body-incorporated phone.

A study provides evidence that talking into a person’s right ear can affect behavior more effectively than talking into the left.

One of the best known asymmetries in humans is the right ear dominance for listening to verbal stimuli, which is believed to reflect the brain’s left hemisphere superiority for processing verbal information.

I heavily prefer my left ear for phone calls. So much so that I have trouble understanding people on the phone when I use my right ear. Should I be concerned that my brain seems to be inverted?

Read on and it becomes clear that going beyond perceptual psychology, the scientists are terrifically shrewd:

Tommasi and Marzoli’s three studies specifically observed ear preference during social interactions in noisy night club environments. In the first study, 286 clubbers were observed while they were talking, with loud music in the background. In total, 72 percent of interactions occurred on the right side of the listener. These results are consistent with the right ear preference found in both laboratory studies and questionnaires and they demonstrate that the side bias is spontaneously displayed outside the laboratory.

In the second study, the researchers approached 160 clubbers and mumbled an inaudible, meaningless utterance and waited for the subjects to turn their head and offer either their left of their right ear. They then asked them for a cigarette. Overall, 58 percent offered their right ear for listening and 42 percent their left. Only women showed a consistent right-ear preference. In this study, there was no link between the number of cigarettes obtained and the ear receiving the request.

In the third study, the researchers intentionally addressed 176 clubbers in either their right or their left ear when asking for a cigarette. They obtained significantly more cigarettes when they spoke to the clubbers’ right ear compared with their left.

I’m picturing the scientists using their grant money to pay cover at dance clubs and try to obtain as many cigarettes as possible – carefully collecting, then smoking, their data – with the added bonus that their experiment happens to require striking up conversation with clubbers of the opposite sex who are dancing alone. One assumes that, if the test subject happened to be attractive, once the cigarette was obtained (or not) the subject was invited out onto the terrace so the scientist could explain the experiment and his interesting line of work. Well played!

Another MRI study, this time investigating how we learn parts of speech:

The test consisted of working out the meaning of a new term based on the context provided in two sentences. For example, in the phrase “The girl got a jat for Christmas” and “The best man was so nervous he forgot the jat,” the noun jat means “ring.” Similarly, with “The student is nising noodles for breakfast” and “The man nised a delicious meal for her” the hidden verb is “cook.”

“This task simulates, at an experimental level, how we acquire part of our vocabulary over the course of our lives, by discovering the meaning of new words in written contexts,” explains Rodríguez-Fornells. “This kind of vocabulary acquisition based on verbal contexts is one of the most important mechanisms for learning new words during childhood and later as adults, because we are constantly learning new terms.”

The participants had to learn 80 new nouns and 80 new verbs. By doing this, the brain imaging showed that new nouns primarily activate the left fusiform gyrus (the underside of the temporal lobe associated with visual and object processing), while the new verbs activated part of the left posterior medial temporal gyrus (associated with semantic and conceptual aspects) and the left inferior frontal gyrus (involved in processing grammar).

This last bit was unexpected, at first. I would have guessed that verbs would be learned in regions of the brain associated with motor action. But according to this study, verbs seem to be learned only as grammatical concepts. In other words, knowledge of what it means to run is quite different than knowing how to run. Which makes sense if verb meaning is accessed by representational memory rather than declarative memory.

Researchers at the University of Tampere in Finland found that,

Interfaces that vibrate soon after we click a virtual button (on the order of tens of milliseconds) and whose vibrations have short durations are preferred. This combination simulates a button with a “light touch” – one that depresses right after we touch it and offers little resistance.

Users also liked virtual buttons that vibrated after a longer delay and then for a longer subsequent duration. These buttons behaved like ones that require more force to depress.

This is very interesting. When we think of multimodal feedback needing to make cognitive sense, synchronization first comes to mind. But there are many more synesthesias in our experience that can only be uncovered through careful reflection. To make an interface feel real, we must first examine reality.

Researchers at the Army Research Office developed a vibrating belt with eight mini actuators — “tactors” — that signify all the cardinal directions. The belt is hooked up to a GPS navigation system, a digital compass and an accelerometer, so the system knows which way a soldier is headed even if he’s lying on his side or on his back.

The tactors vibrate at 250 hertz, which equates to a gentle nudge around the middle. Researchers developed a sort of tactile morse code to signify each direction, helping a soldier determine which way to go, New Scientist explains. A soldier moving in the right direction will feel the proper pattern across the front of his torso. A buzz from the front, side and back tactors means “halt,” a pulsating movement from back to front means “move out,” and so on.

Recent research reveals some fun facts about aural-tactile synesthesia:

Both hearing and touch, the scientists pointed out, rely on nerves set atwitter by vibration. A cell phone set to vibrate can be sensed by the skin of the hand, and the phone’s ring tone generates sound waves — vibrations of air — that move the eardrum…

A vibration that has a higher or lower frequency than a sound… tends to skew pitch perception up or down. Sounds can also bias whether a vibration is perceived.

The ability of skin and ears to confuse each other also extends to volume… A car radio may sound louder to a driver than his passengers because of the shaking of the steering wheel. “As you make a vibration more intense, what people hear seems louder,” says Yau. Sound, on the other hand, doesn’t seem to change how intense vibrations feel.

Max Mathews, electronic music pioneer, has died.

Though computer music is at the edge of the avant-garde today, its roots go back to 1957, when Mathews wrote the first version of “Music,” a program that allowed an IBM 704 mainframe computer to play a 17-second composition. He quickly realized, as he put it in a 1963 article in Science, “There are no theoretical limits to the performance of the computer as a source of musical sounds.”

Rest in peace, Max.

UPDATE: I haven’t updated this blog in a while, and I realized after posting this that my previous post was about the 2010 Modulations concert. Max Mathews played at Modulations too, and that was the last time I saw him.

I finally got around to recording and mastering the set I played at the CCRMA Modulations show a few months back. Though I’ve been a drum and bass fan for many years, this year’s Modulations was the first time I’d mixed it for others. Hope you like it!

Over the last few days this video has been so much bombshell to many of my music-prone friends.

It’s called the Multi-Touch Light Table and it was created by East Bay-based artist/fidget-house DJ Gregory Kaufman. The video is beautifully put together, highlighting the importance of presentation when documenting new ideas.

I really like some of the interaction ideas presented in the video. Others, I’m not so sure about. But that’s all right: the significance of the MTLT is that it’s the first surface-based DJ tool that systematically accounts for the needs of an expert user.

Interestingly, even though it looks futuristic and expensive to us, interfaces like this will eventually be the most accessible artistic tools. Once multi-touch surface are ubiquitous, the easiest way to gain some capability will be to use inexpensive or open-source software. The physical interfaces created for DJing, such as Technics 1200s, are prosthetic objects (as are musical instruments), and will remain more expensive because mechanical contraptions will always be. Now, that isn’t to say that in the future our interfaces won’t evolve to become digital, networked, and multi-touch sensitive, or even that their physicality will be replaced with a digital haptic display. But one of the initial draws of the MTLT—the fact of its perfectly flat, clean interactive surface—seems exotic to us right now, and in the near future it will be default.

Check out this flexible interface called impress. Flexible displays just look so organic and, well impressive. One day these kinds of surface materials will become viable displays and they’ll mark a milestone in touch computing.

It’s natural to stop dancing between songs. The beat changes, the sub-rhythms reorient themselves, a new hook is presented and a new statement is made. But stopping dancing between songs is undesirable. We wish to lose ourselves in as many consecutive moments as possible. The art of mixing music is to fulfill our desire to dance along to continuous excellent music, uninterrupted for many minutes (or, in the best case, many hours) at a time. (Even if we don’t explicitly move our bodies to the music, when we listen our minds are dancing; the same rules apply.)

I don’t remember what prompted me to take that note, but it was probably not that the mixing was especially smooth.

LHCSound is a site where you can listen to sonified data from the Large Hadron Collider. Some thoughts:

  • That’s one untidy heap of a website. Is this how it feels to be inside the mind of a brilliant physicist?
  • The name “LHCSound” refers to “Csound”, a programming language for audio synthesis and music composition. But how many of their readers will make the connection?
  • If they are expecting their readers to know what Csound is, then their explanation of the process they used for sonification falls way short. I want to know the details of how they mapped their data to synthesis parameters.
  • What great sampling material this will make. I wonder how long before we hear electronic music incorporating these sounds.

The Immersive Pinball demo I created for Fortune’s Brainstorm:Tech conference was featured in a BBC special on haptics.

I keep watching the HTC Sense unveiling video from Mobile World Congress 2010. The content is pretty cool, but I’m more fascinated by the presentation itself. Chief marketing officer John Wang gives a simply electrifying performance. It almost feels like an Apple keynote.

The iFeel_IM haptic interface has been making rounds on the internet lately. I tried it at CHI 2010 a few weeks ago and liked it a lot. Affective (emotional haptic) interfaces are full of potential. IFeel_IM mashes together three separate innovations:

  • Touch feedback in several different places on the body: spine, tummy, waist.
  • Touch effects that are generated from emotional language.
  • Synchronization to visuals from Second Life

All are very interesting. The spine haptics seemed a stretch to me, but the butterfly-in-the-tummy was surprisingly effective. The hug was good, but a bit sterile. Hug interfaces need nuance to bring them to the next level of realism.

The fact that the feedback is generated from the emotional language of another person seemed to be one of the major challenges—the software is built to extract emotionally-charged sentences using linguistic models. For example, if someone writes “I love you” to you, your the haptic device on your tummy will react by creating a butterflies-like sensation. As an enaction devotee I would rather actuate a hug with a hug sensor. Something about the translation of words to haptics is difficult for me to accept. But it could certainly be a lot of fun in some scenarios!

I recently started using Eclipse on OS X and it was so unresponsive, it was almost unusable. Switching tabs was slow, switching perspectives was hella slow. I searched around the web for a solid hour for how to make it faster and finally found the solution. Maybe someone can use it.

My machine is running OS X 10.5, and I have 2 GB of RAM. (This is important because the solution requires messing with how Eclipse handles memory. If you have a different amount of RAM, these numbers may not work and you’ll need to fiddle with them.)

  • Save your work and quit Eclipse.
  • Open the Eclipse application package by right-clicking (or Control-clicking) on Eclipse.app and select “Show Package Contents.”
  • Navigate to Contents→MacOS→, and open “eclipse.ini” in your favorite text editor.
  • Edit the line that starts with -”XX:MaxPermSize” to say “-XX:MaxPermSize=128m”.
  • Before that line, add a line that says “-XX:PermSize=64m”.
  • Edit the line that starts with “-Xms” to say “-Xms40m”.
  • Edit the line that starts ith “-Xmx” to say “-Xmx768m”.
  • Save & relaunch Eclipse.

Worked like a charm for me.

“And reaching up my hand to try, I screamed to feel it touch the sky.”

Check out this beautiful kinetic typography piece by Heebok Lee:

It’s based on an excerpt of the poem “Renascence” by Edna St. Vincent Millay.

renascence
noun
1. the revival of something that has been dormant.
2. another term for ‘renaissance.’
(Oxford English Dictionary)

Millay, who wrote the poem when she was only 20 years old, originally called it “Renaissance.” It’s interesting that the two words are so close in meaning and are pronounced almost the same way, but they’re not considered alternate spellings of the same word.

Renascence

ALL I could see from where I stood
Was three long mountains and a wood;
I turned and looked the other way,
And saw three islands in a bay.
So with my eyes I traced the line
Of the horizon, thin and fine,
Straight around till I was come
Back to where I’d started from;
And all I saw from where I stood
Was three long mountains and a wood.
Over these things I could not see:
These were the things that bounded me;
And I could touch them with my hand,
Almost, I thought, from where I stand.
And all at once things seemed so small
My breath came short, and scarce at all.
But, sure, the sky is big, I said;
Miles and miles above my head;
So here upon my back I’ll lie
And look my fill into the sky.
And so I looked, and, after all,
The sky was not so very tall.
The sky, I said, must somewhere stop,
And—sure enough!—I see the top!
The sky, I thought, is not so grand;
I ’most could touch it with my hand!
And reaching up my hand to try,
I screamed to feel it touch the sky.
I screamed, and—lo!—Infinity
Came down and settled over me;
Forced back my scream into my chest,
Bent back my arm upon my breast,
And, pressing of the Undefined
The definition on my mind,
Held up before my eyes a glass
Through which my shrinking sight did pass
Until it seemed I must behold
Immensity made manifold;
Whispered to me a word whose sound
Deafened the air for worlds around,
And brought unmuffled to my ears
The gossiping of friendly spheres,
The creaking of the tented sky,
The ticking of Eternity.
I saw and heard and knew at last
The How and Why of all things, past,
And present, and forevermore.
The Universe, cleft to the core,
Lay open to my probing sense
That, sick’ning, I would fain pluck thence
But could not,—nay! But needs must suck
At the great wound, and could not pluck
My lips away till I had drawn
All venom out.—Ah, fearful pawn!
For my omniscience paid I toll
In infinite remorse of soul.
All sin was of my sinning, all
Atoning mine, and mine the gall
Of all regret. Mine was the weight
Of every brooded wrong, the hate
That stood behind each envious thrust,
Mine every greed, mine every lust.
And all the while for every grief,
Each suffering, I craved relief
With individual desire,—
Craved all in vain! And felt fierce fire
About a thousand people crawl;
Perished with each,—then mourned for all!
A man was starving in Capri;
He moved his eyes and looked at me;
I felt his gaze, I heard his moan,
And knew his hunger as my own.
I saw at sea a great fog bank
Between two ships that struck and sank;
A thousand screams the heavens smote;
And every scream tore through my throat.
No hurt I did not feel, no death
That was not mine; mine each last breath
That, crying, met an answering cry
From the compassion that was I.
All suffering mine, and mine its rod;
Mine, pity like the pity of God.
Ah, awful weight! Infinity
Pressed down upon the finite Me!
My anguished spirit, like a bird,
Beating against my lips I heard;
Yet lay the weight so close about
There was no room for it without.
And so beneath the weight lay I
And suffered death, but could not die.

Long had I lain thus, craving death,
When quietly the earth beneath
Gave way, and inch by inch, so great
At last had grown the crushing weight,
Into the earth I sank till I
Full six feet under ground did lie,
And sank no more,—there is no weight
Can follow here, however great.
From off my breast I felt it roll,
And as it went my tortured soul
Burst forth and fled in such a gust
That all about me swirled the dust.

Deep in the earth I rested now;
Cool is its hand upon the brow
And soft its breast beneath the head
Of one who is so gladly dead.
And all at once, and over all
The pitying rain began to fall;
I lay and heard each pattering hoof
Upon my lowly, thatchèd roof,
And seemed to love the sound far more
Than ever I had done before.
For rain it hath a friendly sound
To one who’s six feet under ground;
And scarce the friendly voice or face:
A grave is such a quiet place.

The rain, I said, is kind to come
And speak to me in my new home.
I would I were alive again
To kiss the fingers of the rain,
To drink into my eyes the shine
Of every slanting silver line,
To catch the freshened, fragrant breeze
From drenched and dripping apple-trees.
For soon the shower will be done,
And then the broad face of the sun
Will laugh above the rain-soaked earth
Until the world with answering mirth
Shakes joyously, and each round drop
Rolls, twinkling, from its grass-blade top.
How can I bear it; buried here,
While overhead the sky grows clear
And blue again after the storm?
O, multi-colored, multiform,
Beloved beauty over me,
That I shall never, never see
Again! Spring-silver, autumn-gold,
That I shall never more behold!
Sleeping your myriad magics through,
Close-sepulchred away from you!
O God, I cried, give me new birth,
And put me back upon the earth!
Upset each cloud’s gigantic gourd
And let the heavy rain, down-poured
In one big torrent, set me free,
Washing my grave away from me!

I ceased; and through the breathless hush
That answered me, the far-off rush
Of herald wings came whispering
Like music down the vibrant string
Of my ascending prayer, and—crash!
Before the wild wind’s whistling lash
The startled storm-clouds reared on high
And plunged in terror down the sky,
And the big rain in one black wave
Fell from the sky and struck my grave.
I know not how such things can be;
I only know there came to me
A fragrance such as never clings
To aught save happy living things;
A sound as of some joyous elf
Singing sweet songs to please himself,
And, through and over everything,
A sense of glad awakening.
The grass, a-tiptoe at my ear,
Whispering to me I could hear;
I felt the rain’s cool finger-tips
Brushed tenderly across my lips,
Laid gently on my sealèd sight,
And all at once the heavy night
Fell from my eyes and I could see,—
A drenched and dripping apple-tree,
A last long line of silver rain,
A sky grown clear and blue again.
And as I looked a quickening gust
Of wind blew up to me and thrust
Into my face a miracle
Of orchard-breath, and with the smell,—
I know not how such things can be!—
I breathed my soul back into me.
Ah! Up then from the ground sprang I
And hailed the earth with such a cry
As is not heard save from a man
Who has been dead, and lives again.
About the trees my arms I wound;
Like one gone mad I hugged the ground;
I raised my quivering arms on high;
I laughed and laughed into the sky,
Till at my throat a strangling sob
Caught fiercely, and a great heart-throb
Sent instant tears into my eyes;
O God, I cried, no dark disguise
Can e’er hereafter hide from me
Thy radiant identity!
Thou canst not move across the grass
But my quick eyes will see Thee pass,
Nor speak, however silently,
But my hushed voice will answer Thee.
I know the path that tells Thy way
Through the cool eve of every day;
God, I can push the grass apart
And lay my finger on Thy heart!

The world stands out on either side
No wider than the heart is wide;
Above the world is stretched the sky,—
No higher than the soul is high.
The heart can push the sea and land
Farther away on either hand;
The soul can split the sky in two,
And let the face of God shine through.
But East and West will pinch the heart
That can not keep them pushed apart;
And he whose soul is flat—the sky
Will cave in on him by and by.
