Tangible User Interface

Tangible User Interface (TUI)

Imagine having a computer system that fuses the physical environment with the digital realm to enable the recognition of real world objects. In Microsoft Pixelsense (formerly known as Surface), the interactive computing surface can recognize and identify objects that are placed onto the screen.
In Microsoft Surface 1.0, light from objects are reflected to multiple infrared cameras. This allows the system to capture and react to the items placed on the screen.

In an advanced version of the technology (Samsung SUR40 with Microsoft PixelSense), the screen includes sensors, instead of cameras to detect what touches the screen. On this surface, you could create digital paintings with paintbrushes based on the input by the actual brushtip.
The system is also programmed to recognize sizes and shapes and to interact with embedded tags e.g. a tagged namecard placed on the screen will display the card’s information. Smartphones placed on the surfaces could trigger the system to display the images in the phone’s gallery onto the screen seamlessly.

How technology will change the future of work

By
How many of us can say, with certainty, what jobs we would choose if we were kids today? The pace of technological change in the time I’ve been in work is only a shadow of what we will see over the next 15 to 20 years. This next wave of change will fundamentally reshape all of our careers, my own included. It’s estimated that some 65% of children entering primary schools today will likely work in roles that don’t currently exist . We expect the pace of change in the job market to start to accelerate by 2020. Office and administrative functions, along with manufacturing and production roles, will see dramatic declines accounting for over six million roles over the next four years . Conversely, business and financial operations along with computer and mathematical functions will see steep rises. There is a central driver for many of these transformations, and it is technology. Artificial intelligence, 3D printing, resource-efficient sustainable production and robotics will f...

Scientists have discovered a way to destroy cancer tumors using nothing but sound waves

By
A recent breakthrough in high-intensity focused ultrasound therapy (HIFU) technology has proven its use as an effective cancer treatment . A multi-institutional research team from China developed a semi-enclosed, spherical cavity transducer that can produce a focused, standing-wave field with a subwavelength-scale focal region and extremely high ultrasound intensity. The spherical cavity transducer appeared to generate tighter focal regions and greater pressure amplitude compared with the traditional concave spherical transducer. Researchers said the level of intensity generated by the new transducer design may lead to significant improvements in HIFU therapy. The findings were published in the Journal of Applied Physics. HIFU is a non-invasive, targeted treatment that makes use of sound waves to eradicate cancer cells . HIFU uses an ultrasonic transducer to convert electrical signals into sound waves, then concentrates ultrasound into a small focal regio...
