Description

GOLF BALL DETECTING OPTICAL DEVICE
This invention relates to a device for detecting a white object in a colored background, and in particular to a golf ball detecting device.
Various technologies have been proposed in the past to assist golfers in finding golf balls. Some inventors have proposed the use of a fluorescent cover on a ball and to illuminate the ball with ultraviolet light to make the bal l glow. Others have proposed the reflection of radio waves from metal plates inside a golf ball to locate the ball. Other proposals include the use of emitters of various types in the core of the ball. However, none of the previous proposals has achieved lasting success. US Patent No. 6,536,905, issued to R.A. Gibbs and the present inventors describes a ball detection viewer similar to the one described herein. However, the patented device does not focus a user's vision efficiently and therefore reduces the likelihood of locating the desired object.
The object of the present invention is to provide a detection device, which enhances the visual perception of a stationary white object, such as a golf ball, to help the user locate the object.
Accordingly, the invention relates to a detection device for increasing the visibility of a white object in a colored background comprising: at least one filter adapted to block approximately 90% of all light having a wavelength above 500 nanometers, less than 10% of all light having a wavelength above 500 nanometers, and approximately 50% of all light having a wavelength of 500 nanometers; a frame carrying said at least one filter; and opaque shields on said frame for blocking side portions of a peripheral area of said filter to force a user of the device to use the portion of an eye with the highest visual acuity.
The device preferably includes a pair of lenses mounted in eyeglass frames with a pair of opaque side shields. The side shields limit peripheral vision of a user. When used by a golfer, the device helps the golfer to avoid penalty strokes, wasting time and expense due to lost balls. The present invention also improves golf course efficiency by reducing ball searching time and consequently round times. Eyeglasses containing the device can be relatively inexpensive, light and portable and can be used by any player under a wide range of weather and background conditions. The invention can be used, without modification, to find any light-colored object in a background that reflects colors different from the color of the object being sought.

Figure 2 is a graph illustrating the light transmission characteristics of the prior art device and of the invention;
Figure 3 is an isometric view of a pair of eyeglasses incorporating the detection device of the present invention;
Figure 4 is a schematic diagram showing a person using the prior art device;
Figure 5 is a schematic diagram showing the area of highest visual acuity of a person using the prior art device;
Figure 6 is a schematic diagram showing the field of vision blocked by the device of the present invention; and
Figure 7 is a schematic diagram showing a focused field of vision using the device of the present invention.
Referring to Fig. 1 , the light reflected from foliage 1 , tree trunks 2, undergrowth 3, grass 4, dirt or gravel 5 and a ball 6 is represented by arrows. A filter 7 blocks most of the light reflected by the foliage 1 , tree trunks 2, undergrowth 3, grass 4, dirt or gravel 5 as indicated by the arrowheads abutting the filter 7. The filter 7 allows the light reflected by the ball 6 to pass through to the eye 8 of a user.
The characteristics of the filter 7 are illustrated in Fig. 2. The characteristics are shown in the form of light transmission in percentage for different wavelengths of light in nanometers. The filter 7 transmits light in the blue color range and attenuates the transmission of light with wavelengths over 500 nanometer (500 nm). Such a filter attenuates colors most commonly found in vegetation, i.e. greens, yellows, oranges and reds; and transmits the blue and violet colors which are not reflected to a much greater extent by white objects. The degree of transmission of light through the filter 7 above approximately 500 nm should be less than 15%, and the degree of transmission of light at wavelengths shorter than 500 nm should be more than 30%. A preferred filter 7 is a plastic filter sold by Rosco Corporation under the trade name Roscolux #85 "Deep blue"TIM.
The filter is advantageous because it has a good light transmission below the 500 nm mark, a good light attenuation above the 500 nm mark, and a sharp drop in light transmission at the 500 nm mark. As can be seen in Fig. 2, the light transmission curve of the filter shows a light transmission of about 90% below 500 nm and a light transmission of less than 10% above 500 nm. The light transmission curve makes a sharp drop at the 500 nm mark, showing a light transmission of 50% at that wavelength. In other words, the filter blocks about 90% of the light coming from a vegetative background and blocks only less than about 10% of the light reflected from a white object.
Referring to Fig. 3, in accordance with the present invention, filters 7 of the type described above are mounted in eyeglasses 10. The eyeglasses 10 include a conventional frame 11 for holding the filters 7 and temples 12 for supporting the glasses on the head of a user. In accordance withi the present invention, opaque shields 13 and 14 are provided at each side of the frame 11. The shields 13 and 14 extends forwardly from the frame sides for limiting a wearer's lateral field of view. While the shields 13 and 14 have concave front ends 15, it will be appreciated that other shapes can be used.
Fig. 4 is an schematic overhead view of a person 16. Lines 17 and 18 border the person's lateral field of vision. The filed of vision can be divided for each eye into two regions. The left temporal region 19 is shown in Fig. 4 bordered by lines 17 and 20). The right temporal region 21 is bordered by lines 18 and 22.
Referring to Fig. 5, the lines 23 and 24 border the field of vision 25 accounting for 90% of the average person's visual acuity.
With reference to Fig. 6, for a person using the glasses described above, the left side shield 13 blocks a portion 27 of the temporal region bounded by lines 28 and 29. The right side shield 14 blocks a portion 30 of the temporal region bounded by lines 31 and 32. This limits the person's field of vision to region 34 which is bounded by lines 29 and 31.
As illustrated in Fig. 7, when a person using the device moves his or her head from left to right (clockwise in Fig. 6) the high acu ϊty vision region 25 described with reference to Fig. 5 is focused near the opaque side shield 14 of the glasses. The opaque side shield 14 blocks the temporal region 38 bounded by lines 39 and 40 and the user can see through the high acuity region 25 bounded by lines 39 and 42.
Blocking a portion of the peripheral vision of a user increases the efficacy of the lenses for two reasons. Firstly, as users look from side to side by turning their head, the natural tendency is for the eyes to fixate on new info rmation being presented, i.e. the eyes will focus on the information just coming in to view. By encouraging users to focus on this region, the portions of their vision with the highest visual acuity is used to analyze new information while limiting thie frequency of saccades. In this connection, reference is made to "Global Effects of Feature-Based Attention in Human Visual Cortex" by Melissa Saenz, Giedrius T. Bucacas & Geoffrey M. Boynton. For the average person the portion of thϊ eir vision with the highest visual acuity can be represented by a 10° (degree) cone starting from the person's eye. Outside of this convergence region the average visual acuity drops by 90%.
Secondly, with the earlier device described above, the ball would slowly come into view through the user's peripheral vision and given the natural saccades it would be possible to miss the ball. By blocking the peripheral vision and moving the head from side to side, the ball will suddenly appear from the blocked region. This sudden 'reveal' or flash of white will increase the likelihood that the user will fixate on the white object thereby greatly increasing the efficacy of the invention.
For the average person the horizontal field of vision for each eye can be divided into two regions; the temporal region 19 and the nasal region 20 (both regions are shown on Fig. 4 for the left eye). The temporal region is on average 110° from the central axis 18 and the nasal region is on average 60° from the central axis. The nasal region is influenced by the size and shape of the person's nose. The filter of the present invention blocks a certain amount of trie temporal region for the purposes outlined above. If too much of the region is blocked then it limits the person's ability to navigate and search for the ball (vision region of 120° is often required for driving) and if too little is blocked then the 'reveal' effect and the use of the person's high visual acuity is lost. For the purposes of this invention, the regions 27 and 30 blocked by the opaque shields 13 and 14 are each set to be between 20° and 40°. That is, the frames of the glasses are designed such that the angle of the region 27 blocked for the left side bounded by lines 28 and 29 is between 20° and 40° and that the angle of the region 30 blocked for the right side bounded by lies 31 and 32 is between 20° and 40°.
