Haptic technology wheel to simulate forces found when cornering a real vehicle. In 2007, Novint released the Falcon, the first consumer 3D touch device with high resolution three-dimensional force feedback; this allowed the haptic simulation of objects, textures, recoil, momentum, and the physical presence of objects in games. Non-contact, or mid-air, haptic technology utilizes the sense of touch without physical contact of a device. This type of feedback involves interactions with a system that are in a 3D space around the user. Thus, the user is able to perform actions on a system in the absence of holding a physical input device.
Word-sense disambiguation is that similar senses occur in similar contexts, and thus senses can be induced from text by clustering word occurrences using some measure of similarity of context, a task referred to as word sense induction or discrimination. Then, new occurrences of the word can be classified into the closest induced clusters/senses. Performance has been lower than for the other methods described above, but comparisons are difficult since senses induced must be mapped to a known dictionary of word senses. If a mapping to a set of dictionary senses is not desired, cluster-based evaluations (including measures of entropy and purity) can
