Power limiting progress in mobile devices

Neil TrevettPower is a big limitation in mobile devices despite improvements in battery power, according to Neil Trevett, Vice President Mobile Content of NVIDIA.

“Power is the new performance limiter. Developers need to use acceleration to preserve battery life and high performance,” he said at NVIDIA Tech Talk at SIGGRAPH Asia in Hong Kong.

On the other hand, advanced mobile GPUs and new sensors are combining to make vision processing the next wave of mobile visual processing. NVIDIA is building a stack of advanced silicon, APIs and libraries to enable advanced mobile vision applications.

Smartphones sport up to 19 sensors

Most of us are aware that smartphones have numerous sensors that, well, help to make them smart. But, most believe the number of sensors to be around six to eight. At a presentation at SIGGRAPH Asia 2012 in Singapore, Neil Trevett, Vice President of Mobile Content of NVIDIA, revealed that smartphones sport up to 19 sensors.

He noted that a lot of development that leverages the combined capabilities of these sensors is happening with today’s devices.

Copyright hindering democratisation of 3D

Increasing power of GPUs is enabling designers to create 3D models quicker and in greater detail. Such additional details may include specific models of cars, cameras or other products instead of just generic models. This should pave the way towards democratisation of 3D.

However, a major barrier can halt this progress.

While creating a specific product is now easier, using that created model may be a challenge. Standing in the way are copyright laws and more importantly, copyright owners.

“Copyright owners own the right to models of their products. They can decide whether users can use or should remove 3D models of their products. Users need to seek permission to use such models,” said Gavin Greenwalt, Senior Artist of Straightface Studios.
