An Advanced Micro Devices demonstration featured "Angry Birds" and "Candy Crush" gameplay using hand gestures with a desktop, though the computer lagged in responding.
A webcam captured the hand movement and processed it through an algorithm, and the hand gesture was reflected in the games.
Intel wants to take that a step further through its Perceptual Computing effort, which allows more forms of sensory input to make human interactions with computers easier.
PCs with 3-D cameras, which will ship at the end of this year, will track movement, recognize human emotions and capture habits. Applications for this form of interaction through Intel's software development kit are under development.
The end of DDR3 is near with upcoming DDR4 memory, which could be the last form of nonvolatile memory in computers.
Crucial and Adata showed DDR4 modules, and Intel is shipping gaming PCs and servers with DDR4 support in the third quarter.
DDR4 offers 50 percent more bandwidth and is 35 percent more power-efficient than previous memory. However, initial units of DDR4 memory could be expensive, but prices are likely to fall as adoption grows and more units ship.
