Interactions between instruction visualisations and task mental representations in skill acquisition is arguably knowledge-domain dependent. This paper presents the design and preliminary results of an experiment that extends the knowledge-domain dependent model to the acquisition of spatial navigational skills. A between-group design is proposed and tested to compare post-learning navigational...

To better meet users’ underlying navigational requirement, search engines like Baidu has developed general recommendation engine and provided related entities on the right side of the search engine results page(SERP). However, users’ behavior have not been well investigated after the association of individual queries in search engine. To better understand users’ navigational activities, we prop...

The prominent mandibular angle is considered as unattractive in Asians because it gives the face a square, coarse, and muscular appearance. Mandibular angle osteotomy (MAO) is commonly used to correct prominent mandibular angles through an intraoral approach. This study aims to improve the accuracy and safety of surgery for MAO through optimized design of 3D printing navigational template. Comp...

Primary Objective: Compare the effects of written landmark, cardinal, and left/right street directions on navigational success at the beginning of a walking route. Research Design: Matched control group comparison design Methods & Procedures: We compared navigational performance of 18 adults with acquired brain injury (ABI) to controls matched for gender, age, and education. Participants follow...

Unlike for other abilities, children do not receive systematic spatial orientation training at school, even though navigational training during adulthood improves spatial skills. We investigated whether navigational training programme (NTP) improved spatial orientation skills in pre-schoolers. We administered 12-week NTP to seventeen 4- to 5-year-old children (training group, TG). The TG childr...

We present a semantically rich graph representation for indoor robotic navigation. Our graph representation encodes: semantic locations such as offices or corridors as nodes, and navigational behaviors such as enter office or cross a corridor as edges. In particular, our navigational behaviors operate directly from visual inputs to produce motor controls and are implemented with deep learning a...

Portal Catalogs is a popular means of searching for information on the Web. They provide querying and browsing capabilities on data organized in a hierarchy, on a category/subcategory basis. This paper presents mining techniques on user navigational patterns in the hierarchies of portal catalogs. Specifically, we study and implement navigation retrieval methods and clustering tasks based on nav...

We present a novel method of combining eye tracking with specially designed virtual environments to provide objective evidence of navigational strategy selection. A simple, inexpensive video camera with an easily built infrared LED array is used to capture eye movements at 60Hz. Simple algorithms analyze gaze position at the start of each virtual maze trial to identify stimuli used for navigati...

Seafarers’ doubting about the electronic chart display and information system is a widespread problem. To better explain, predict, and increase user acceptance, this research focused on the impact of navigational risks to address and predict shipmates' computer acceptance by a measure of their intentions, attitudes, perceived usefulness, and perceived ease of use. Thus a hypothesized model was ...

Wayfinding research has inspired several algorithms that compute the shortest, fastest, or even simplest paths between two locations. Current navigation systems, however, do not take into account the navigational complexity of certain intersections. A short route might involve a number of intersections that are difficult to navigate, because they offer more than one alternative to turn left or ...
