While controllers can support many generic 3D interactions in virtual reality (VR), it alone may fall short of eliciting the core experience for certain actions. One such task is the “object throwing’’, ubiquitous in many sports contents, involving ...

Costumer targeting is becoming critical for successful advertising and client retention. In this case we studied the performance of a targeting model in terms of adoption and profitability. The base model chooses a set of clients to offer them ...

Recent computer vision advances can enable television control using midair barehand input, for which selecting targets using hand positions is a primary task. Yet, the size and position of a preferred 2D interaction region has not been specifically ...

In voicing commitments to the principle that the adoption of artificial-intelligence (AI) tools by armed forces should be done responsibly, a growing number of states have referred to a concept of “Responsible AI.” As part of an effort to help ...

We propose PinpointFly, an egocentric drone interface that allows users to arbitrarily position and rotate a flying drone using position control interactions on a see-through mobile AR where the position and direction of the drone are visually enhanced ...

Yam (Dioscorea spp.) is a major staple crop with high agricultural and cultural significance for over 300 million people in West Africa. Despite its importance, productivity is miserably low. A better understanding of the environmental context in the ...

• Targeting of advice can be improved with little household data collected through ICT.

In recent years, agricultural extension services in developing countries have increasingly introduced modern information and communication technologies (ICT) to deliver advice. But to realize efficiency gains, digital applications may ...

This article analyzes a mechanism for selling items in auctions in which the auctioneer specifies a cap on the ratio between the maximum and minimum bids that bidders may use in the auctions. Such a mechanism is widely used in online advertising through ...

We report on an exploratory study investigating the relationship of users' hand sizes and aspects of their mobile touch interactions. Estimating hand size from interaction could inform, for example, UI adaptation, occlusion-aware UIs, and biometrics. We ...

In this study, we present a class of nonlinear analytical solutions for the dynamics of a fixed wing unmanned aircraft vehicle (UAV). These solutions are needed for the integration and fusion of sensor data for input to guidance and control algorithms. ...

• A model for predicting churn one day after registration in games is proposed.
• ...

Customer churn is a widely known term in many industries, including banking, telecommunications and gaming. By definition, churn represents the act of a customer leaving a product for good. Most commonly, late customer churn is ...

In second-price auctions, we find that improved targeting via enhanced information disclosure decreases revenue when there are two bidders and increases revenue if there are at least four symmetric bidders with values drawn from a distribution with a ...

Information about location of marginal lands in a watershed is of interest to those who view these areas as potential land for producing biofuel crops. However, representing marginal lands into a distributed model such as the Soil and Water Assessment ...

We find the optimal fire distribution for the one-against-many Lanchester aimed-fired model, in which a homogeneous Blue force fights a mixed Red force with several distinct types. Each unit of Blue force kills Red type i at rate b i , while each type- ...

Image retargeting adjusts images to arbitrary sizes such that they can be viewed on different displays. Content-aware image retargeting has been receiving increased attention. In particular, researchers have improved a patch-wise scaling method for image ...

As marketing communications proliferate, the ability to target the right audience for a message is of ever-increasing importance. Audience targeting practices for mass media, both in research and in industry, have tended to emphasize demographics, ...

Automatic localization and targeting are critical steps in automating the process of microinjecting adherent cells. This process is currently performed manually by highly trained operators and is characterized as a laborious task with low success rate. ...

Targeted cyberattacks play an increasingly significant role in disrupting the online social and economic model, not to mention the threat they pose to nation-states. A variety of components and techniques come together to bring about such attacks.

In e-commerce, where competition is tough and customers' preferences can change quickly, it is crucial for companies to segment customers and target marketing actions effectively. The process of segmentation and targeting is effective if the customers ...

The human–computer interface remains a mostly visual environment with little or no haptic interaction. While haptics is finding inroads in specialized areas such as surgery, gaming, and robotics, there has been little work to bring haptics to the ...
