Question: What was the Australian art movement of the late 19th century described as, who's artists frequent a self-drive, cycling and walking trail that includes a series of 57 explanatory signs and boards situated in locations?

<P0-S0>  The movement has latterly been described as Australian Impressionism. <P0-S1> The Heidelberg School was an Australian art movement of the late 19th century. <SEP> <P1-S0> Eye movement in reading involves the visual processing of written text. <P1-S1>  This was described by the French ophthalmologist Louis Émile Javal in the late 19th century. <P1-S2>  He reported that eyes do not move continuously along a line of text, but make short, rapid movements (saccades) intermingled with short stops (fixations). <P1-S3>  Javal's observations were characterised by a reliance on naked-eye observation of eye movement in the absence of technology. <P1-S4>  From the late 19th to the mid-20th century, investigators used early tracking technologies to assist their observation, in a research climate that emphasised the measurement of human behaviour and skill for educational ends. <P1-S5>  Most basic knowledge about eye movement was obtained during this period. <P1-S6>  Since the mid-20th century, there have been three major changes: the development of non-invasive eye-movement tracking equipment; the introduction of computer technology to enhance the power of this equipment to pick up, record and process the huge volume of data that eye movement generates; and the emergence of cognitive psychology as a theoretical and methodological framework within which reading processes are examined. <P1-S7>  Sereno & Rayner (2003) believed that the best current approach to discover immediate signs of word recognition is through the recordings of eye movements and event-related potential. <SEP> <P2-S0>  The signs display reproductions and descriptions of some of the most famous paintings, and are popular with school groups who have an interest in the arts and the natural environment. <P2-S1>  The trail winds for approximately 40 km through much of Jagajaga, including the municipalities of Banyule, Nillumbik and Manningham, through to the Yarra Valley and the Dandenong Ranges. <P2-S2> The Heidelberg Artists Trail is a self-drive, cycling and walking trail that includes a series of 57 explanatory signs and boards situated in locations frequented by artists of the Heidelberg School. <SEP> <P3-S0> Proto-Cubism (also referred to as Protocubism, Pre-Cubism or Early Cubism) is an intermediary transition phase in the history of art chronologically extending from 1906 to 1910. <P3-S1>  Evidence suggests that the production of proto-Cubist paintings resulted from a wide-ranging series of experiments, circumstances, influences and conditions, rather than from one isolated static event, trajectory, artist or discourse. <P3-S2>  With its roots stemming from at least the late 19th century this period can be characterized by a move towards the radical geometrization of form and a reduction or limitation of the color palette (in comparison with Fauvism). <P3-S3>  It is essentially the first experimental and exploratory phase of an art movement that would become altogether more extreme, known from the spring of 1911 as Cubism.
