Definitions
- the present disclosure relates to a guide stick for blind or partially sighted persons.
- Guide sticks or canes are used by blind or partially sighted persons to assist them with avoiding hazards or obstacles when walking. They also serve to alert other walkers, drivers etc. that the user of the stick is blind or partially sighted. Typically, such a guide stick or cane is white in colour, which is widely recognised as being representative of a guide stick for blind or partially sighted people.
- a guide stick for blind or partially sighted people comprising: a communication device; and at least one sensor for sensing an assistive walkway feature for blind or partially sighted people; the arrangement being such that the communication device is configured to send a notification to a remote apparatus in response to detection by the at least one sensor of a defect with such an assistive walkway feature.
- the guide stick comprises a GPS device, enabling the guide stick to provide location information of the defect to the remote apparatus.
- the remote apparatus comprises a user equipment.
- the remote apparatus comprises an apparatus or server associated with a department or person responsible for the assistive walkway feature.
- the at least one sensor comprises a colour sensor arranged to detect a walkway feature comprising a coloured line.
- the at least one sensor is comprised at a tip end of the walking stick.
- the defect comprises damage to the assistive walkway feature.
- the defect comprises an absence of the assistive walkway feature.
- the guide stick is configured to distinguish between a valid absence of the assistive walkway feature and an invalid absence of the assistive walkway feature.
- the guide stick is configured to send the notification to a remote apparatus in response to detection of an invalid absence of the assistive walkway feature, and is configured to not send the notification to a remote apparatus in response to detection of a valid absence of the assistive walkway feature
- the communication device comprises a radio frequency communication device.
- the communication device has Bluetooth functionality.
- a system comprising: a user equipment; a remote apparatus; and a guide stick for blind or partially sighted people, the guide stick comprising: a communication device; and at least one sensor for sensing an assistive walkway feature for blind or partially sighted people; the arrangement being such that the communication device is configured to send a notification to the user equipment and/or the remote apparatus in response to detection by the at least one sensor of a defect with such an assistive walkway feature.
- the guide stick comprises a GPS device, and wherein in response to detection by the at least one sensor of a defect with such an assistive walkway feature, the guide stick is configured to send the notification and location information of the defect to the user equipment, the user equipment configured to forward the notification and location information to the remote apparatus.
- the guide stick in response to detection by the at least one sensor of a defect with such an assistive walkway feature, is configured to send the notification of the defect to the user equipment, the user equipment configured to use a GPS device of the user equipment to determine location information of the defect, the user equipment configured to forward the notification and location information to the remote apparatus.
- the present disclosure has applicability to guide sticks for blind and/or partially sighted persons.
- Such guide sticks may also be termed guide canes, walking canes, walking sticks etc.
- a user can feel for obstacles in their path by placing or gently waving the cane in front of them as they walk.
- Some modern guide canes sometimes referred to as “smart canes", are fitted with an ultrasonic sensor which can sense a distance from an object, and provide feedback to the user.
- Walkways may be fitted with one or more features for assisting blind or partially sighted people in using the walkway.
- a walkway may be, for example, a pavement or sidewalk, a path, a combined cycle and walkway, a road-crossing, steps or stairs, a ramp, an escalator, a travellator etc.
- Such an assistive feature may comprise, for example, a coloured line (sometimes referred to as a "blind-line").
- the coloured line may be a bright colour such as yellow, orange or red.
- the coloured line is designed to contrast with the other sections of the walkway, which may be black or dark grey, for example.
- Such coloured lines can be useful even for people with significant sight loss, since they may still have sufficient sight to enable them to follow the coloured line. Even for completely blind people these coloured lines can be useful, since guide dogs can be taught to follow them.
- Such assistive features may also comprise, for example, dimpled or otherwise textured walkway features.
- a blind or partially sighted person can feel the textured feature on the soles of their feet, e.g. through the soles of their shoes, to ascertain information regarding the walkway feature.
- a dimpled walkway feature may provide information to a blind or partially sighted person that they are at a crossing, such as a road crossing or a crossing with another walkway.
- raised lines may indicate to a blind or partially sighted person that they are about to step on to a cycle path or a combined walking and cycle path.
- the raised lines may be directional, with longitudinal facing lines (i.e. in the direction of the walkway) indicating a cyclist's side of the path, and lateral lines (i.e. in a direction across the path) indicating a walker's side of the walkway or path.
- Such assistive walkway features can help keep a blind or partially sighted person safely on the walkway, for example so that they do not stray off the walkway and on to a road or in to other danger.
- Such assistive walkway features can also safely guide a walker to or over a road crossing, as well as warning the blind or partially sighted person as they approach the crossing.
- Such assistive walkway features can become damaged or defective over time, and thus lose their functionality. This can also place users of such assistive features, such as blind or partially sighted people, in danger. Furthermore it may take a long time for the department responsible for maintaining the assistive feature (e.g. a local authority) to become aware of and fix the defect and/or damage. This may mean the assistive walkway feature being further damaged in that time, or at least not functioning properly for that time.
- the department responsible for maintaining the assistive feature e.g. a local authority
- Figure 1 is a schematic plan view, showing a blind or partially sighted person 102 walking on a walkway 106.
- the blind or partially sighted person 102 is carrying a guide stick 104.
- the walkway 106 comprises an assistive feature 108 for assisting blind or partially sighted people along the walkway.
- the assistive feature 108 may comprise a coloured line, which contrasts in colour with adjacent parts of the walkway 106.
- the assistive feature 108 comprises a defective or damaged portion 110.
- the defect may comprise, for example, fading or even complete absence of the assistive feature. This may be due to the assistive feature wearing or fading away over time.
- the defect may comprise the assistive feature becoming obscured by one or more items. For example leaves may fall on to the assistive feature 108, reducing or eliminating the functionality of the assistive feature.
- a further assistive walkway feature is shown at 112, comprising a plurality of raised portions or dimples 114.
- the assistive feature 112 is intended to warn blind or partially sighted people that they are approaching a road or another walkway 118.
- the assistive feature 112 comprises defective or damaged portion 116.
- the defect 116 may comprise damage to one or more of the dimples, for example cracking of one or more dimples or absence of part of or complete absence of one or more dimples.
- FIG. 2 shows an example of a guide stick 204 according to an example.
- the guide stick 204 comprises a handle end 230 and a tip end 232. At or proximate to the tip end there is provided one or more sensors 238.
- the one or more sensors may comprise, for example, a colour sensor and/or an ultrasound sensor.
- a colour sensor may be configured to sense colour or colour contrast, and hence be able to sense the presence or absence (or fading) of an assistive feature such as a coloured line on a walkway.
- An ultrasonic sensor may be able to detect or determine a distance from another object. Therefore an ultrasonic sensor may be able to detect presence or absence (or damage) to a raised feature, such as dimples 114.
- the guide stick may, in some examples, provide feedback or an alarm to a user when a defect to an assistive feature is sensed. For example, the guide stick may be arranged to vibrate or provide an audible alarm to warn the user that the assistive feature is defective.
- the guide stick comprises a Global Positioning System (GPS) device 236.
- GPS Global Positioning System
- the GPS device can record location information of the guide stick 204. Consequently the guide stick 204, using the GPS device 236, can record location information of defects to assistive walkway features.
- the guide stick 204 also comprises a communication device 234.
- the communication device 234 may be a radio frequency (RF) communication device.
- the communication device 234 may comprise a transmitter.
- the communication device 234 may also comprise a receiver.
- the communication device 234 may be in the form of a transceiver.
- the communication device 234 may have Bluetooth® functionality or capability.
- the communication device 234 enables the guide stick 204 to communicate with one or more remote apparatuses.
- the communication device 234 enables the guide stick 204 to communicate with a user equipment 246 of a user (the user being, for example, a user of the guide stick), as shown on line or communication channel 250.
- the user equipment may be, for example, a smart phone or tablet of the user.
- the user equipment 246 will typically comprise memory and processing capability, as well as GPS functionality.
- the communication device 234 may additionally or alternatively enable the guide stick 204 to communicate with a remote computer 248, as shown on line or communication channel 254.
- the remote computer 248 may comprise, for example, a computer or server of a department or person responsible for the assistive walkway feature.
- the department may be, for example, a local authority or a contractor to a local authority.
- the guide stick 204 comprises a controller, shown schematically at 240.
- the controller 240 comprises a memory 242 and a processor 244.
- the controller 240 can, for example, receive and process information from one or more of communication device 234, GPS device 236, and at least one sensor 238.
- the controller can also control operations of communication device 234, GPS device 236, and at least one sensor 238.
- the guide stick 204 also comprises a power source 235.
- the power source 235 may be a battery. In some embodiments the power source 235 comprises a rechargeable battery.
- the guide stick 204 is configured to notify a person or department responsible when a defect to an assistive walkway feature is detected. For example this may be by means of informing remote apparatus 248.
- the remote apparatus 248 may be informed by direct communication between the guide stick 204 and remote apparatus 248 (e.g. on line 254), or by indirect communication via user equipment 246 (e.g. on lines 250 and 252).
- the at least one sensor 238 of the guide stick 204 may detect a defect with an assistive walkway feature.
- the guide stick may use GPS device 236 to record the location of the defect. Notification of the defect, and location information of the defect, can then be provided to remote apparatus 248 on line or communication channel 254.
- the guide stick may provide notification of the defect and location information of the defect on line or communication channel 250 to user equipment 246.
- the user equipment 246 can then forward the defect notification and the location information to remote apparatus 248 on line or communication channel 252.
- the user equipment 246 will be with or proximate to the user of guide stick 204, meaning that the communication on line 250 can be, for example, by means of Bluetooth communication. This may save power for the guide stick 204, and/or mean that a relatively less powerful and /or less expensive communication device 234 can be utilised since the communication device 234 in such examples does not have to be powerful enough to transmit directly to remote computer 248, which will typically be a much greater distance away than user equipment 246.
- the GPS device 236 of the guide stick 204 can be omitted.
- the location information of a detected defect may be provided by the user equipment 246.
- the at least one sensor 238 of the guide stick 204 may detect a defect in an assistive walkway feature.
- the guide stick 204 uses communication device 234 the guide stick 204 sends notification of the defect to user equipment 246.
- Such examples are applicable where the user equipment is being carried in close proximity to the user (e.g. in the user's pocket or handbag, rucksack etc.), such that the location of the user equipment still provides an accurate location of the defect.
- Interoperability between the guide stick 204 and the user equipment 246 may be provided by means of an application or "app”, which may be downloaded on to and stored at the user equipment 246.
- the guide stick 204 is configured to distinguish between valid (e.g. acceptable) and invalid (e.g. non-acceptable) defects (or possible defects). For example, where the potential defect is absence of a coloured guide line, then the guide stick is configured to determine whether this is an invalid absence, for example that the guide line should be there but has excessively faded or completely worn away, or a valid absence, for example it is the end of the walkway and therefore the guide line has terminated and intentionally proceeds no further. This prevents or reduces instances of false alarms.
- location information of correct or valid assistive walkway features is stored in the memory 242 of the guide stick 204, or obtained via user equipment 246. If a potential defect is detected, then a cross-check may be made with the information of correct location information of known walkway features, to determine whether the defect is "valid" or "invalid".
- Examples may provide defect information of assistive walkway features, such as coloured "blind-lines", to a party responsible for maintenance of the assistive feature and/or walkway.
- This information may in some examples be provided in "real-time", and give the responsible party an accurate picture of the state of such assistive features at a given location or region.
- This information may be received by the responsible party far more quickly than depending upon routine or periodic inspection. This can help the responsible party not only fix any problems quickly, but also plan maintenance based upon given locations of the detected defects.
- This benefits not only users of blind or partially sighted people using the disclosed guide sticks (as shown for example in Figure 2 ), but also other blind or partially sighted people who rely on such assistive walkway features.
- processor or processing system or circuitry referred to herein may in practice be provided by a single chip or integrated circuit or plural chips or integrated circuits, optionally provided as a chipset, an application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), digital signal processor (DSP), graphics processing units (GPUs), etc.
- the chip or chips may comprise circuitry (as well as possibly firmware) for embodying at least one or more of a data processor or processors and a digital signal processor or processors, which are configurable so as to operate in accordance with the exemplary embodiments.
- the exemplary embodiments may be implemented at least in part by computer software stored in (non-transitory) memory and executable by the processor, or by hardware, or by a combination of tangibly stored software and hardware (and tangibly stored firmware).
- memory for storing data. This may be provided by a single device or by plural devices. Suitable devices include for example a hard disk and non-volatile semiconductor memory.
