We introduce an interactive interface for the custom design of metallophones. The shape of each plate must be determined in the design process so that the metallophone will produce the proper tone when struck with a mallet. Unfortunately, the relationship between plate shape and tone is complex, which makes it difficult to design plates with arbitrary shapes. Our system addresses this problem b...

One common dichotomy faced in recommender systems is that explicit user feedback -in the form of ratings, tags, or user-provided personal informationis scarce, yet the most popular source of information in most state-of-the-art recommendation algorithms, and on the other side, implicit user feedback such as numbers of clicks, playcounts, or web pages visited in a sessionis more frequently avail...

abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...

Tactile feedback from a remotely controlled robotic arm can facilitate certain tasks by enabling the user to experience tactile or force sensations from the robot's interaction with the environment. However, equipping both the robot and the user with tactile sensing and feedback systems can be complex, expensive, restrictive and application specific. This paper introduces a new tele-operation h...

Teaching physical motions such as riding, exercising, swimming, etc. to human beings is hard. Coaches face difficulties in communicating their feedback verbally and cannot correct the student mid-action; teaching videos are two dimensional and suffer from perspective distortion. Systems that track a user and provide him real-time feedback have many potential applications: as an aid to the visua...
