Using Feedforward to Reveal Interaction Possibilities in Virtual Reality
ACM Transactions on Computer-Human Interaction, 2023 In virtual reality (VR), interactions may fail when users encounter new, unknown, or unexpected objects. We propose using feedforward in VR to help users interact with objects by revealing how such objects work. Feedforward lets users know what to do and

Approximate feedforward control
2015 10th Asian Control Conference (ASCC), 2015Disturbances are inevitable in most control systems. They drive the systems away from their set points. It takes time for feedback control to reject them. The feedforward control offers great potentials for regulation performance if the disturbances are measurable.

Predictive feedforward control
2016 12th IEEE International Conference on Control and Automation (ICCA), 2016Measurable but controllable disturbances are common in industry, which drive systems away from their references and take time for feedback control to reject them, especially when the systems present input-output delays due to mechanical properties. In this paper, a novel feedforward control based on disturbance prediction is proposed.

On the equivalence to feedforward forms
2003 European Control Conference (ECC), 2003The problem of (local) coordinates and feedback equivalence of single-input affine nonlinear systems to feedforward forms is studied and solved. The general theory is applied to linear systems, and is illustrated through a simple four dimensional example describing the dynamics of a food-chain.

The paper presents an approach to construction of hierarchical structures of data based concepts (granules), extending the idea of feedforward neural networks. The operations of processing the concept information and changing the concept specification through the network layers are discussed.

Feedforward refers to the transition from briefing to designing in ways that enrich the design with information from the brief (one assumes that a better-informed designer can achieve higher performance than an uninformed one). The first possibility for feedforward that is discussed is the use of the requirements graph in designing, including the ...

Feedforward is an educational strategy in which a professor gives orientations to students, prior to a certain task or assessment, in order to show them how to perform well in that upcoming task. This chapter explores the contribution of screencasts as one possible solution to providing feedforward.

Abstract Abstract This paper demonstrates how feedforward control can assist in stabilizing unstable systems. Feedback control is necessary for stabilization, but feedforward can be used to avoid input constraints which would otherwise cause the system to go unstable.

In recognizing that effective feedback and pedagogical approaches that support social interaction in learning are vital to students' achievement, this chapter focuses on students' need to be actively involved in their learning and assessment. It reports research into how undergraduate education students utilized assessment feedback.
