Integration of speed and time for estimating time to contact
To coordinate movements with events in a dynamic environment the brain has to anticipate when those events occur. A classic example is the estimation of time to contact (TTC), that is, when an object reaches a target. It is thought that TTC is estimated from kinematic variables. For example, a tennis player might use an estimate of distance (d) and speed (v) to estimate TTC (TTC = d/v). However...
متن کاملA Novel Approach to Trace Time-Domain Trajectories of Power Systems in Multiple Time Scales Based Flatness
This paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. The feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. Thus the computation of the flat output for reduced order model of the synchronous machine with simp...
متن کاملEstimating time to contact and impact velocity when catching an accelerating object with the hand.
To catch a moving object with the hand requires precise coordination between visual information about the target's motion and the muscle activity necessary to prepare for the impact. A key question remains open as to if and how a human observer uses velocity and acceleration information when controlling muscles in anticipation of impact. Participants were asked to catch the moving end of a swin...
متن کاملThe time course of estimating time-to-contact: Switching between sources of information
The different sources of information that can be used to estimate time-to-contact may have different degrees of reliability across time. For example, after a given presentation or display time, an absolute change of angular size can be more reliable than the corresponding estimation of the rate of angular expansion (e.g. motion information). One could then expect systematic biases in the observ...
متن کاملWhen Will You Answer This? Estimating Response Time in Twitter
We present a study analyzing the response times of users to questions on Twitter. We investigate estimating these response times using an exponential distribution-based wait time model learned from users’ previous responses. Our analysis considers several different model building approaches, including personalized models for each user, general models built for all users, and time-sensitive mode...
