Flexible Sensing Device
Description
Wearable personal computing devices which have access to the fixed and mobile internet computing devices are now commonplace. Often these devices use microminiature accelerometers (e.g. ST Microelectronics LIS2DH) or gyroscopes to detect accelerative forces when worn by a user.
Commonly these forces can be used to detect physical actions such as waving or shaking and use these actions to trigger device functions. Furthermore, typically these devices are embedded in caseworks such that they can be worn on the body on the wrist (eg: Apple Inc iWatch™).
Several drawbacks exist with the wearing of such devices on the wrist or on clothing in this form. Mounting the unit on the body requires both space to attach the device and, for occasional use, the inconvenience of attaching and de-attaching the device. Sharing of the device can be difficult as in general such devices are intended for personal wear. Furthermore, certain types of hand motor skills may be difficult to detect, for example, squeezing, waving and throwing hand gestures. In addition, such gestures may be preferable for persons who have impaired motor skills.
This invention proposes a method to house such a sensing device within a flexible body which allows these restrictions to be overcome.
Preferred Embodiment
The invention is now described with reference to the following figures:
Figure 1 shows an example of the sensing device
Figure 2 shows an example of how the sensing mechanism may be placed within the sensor device housing
Figure 3 shows a block diagram of the sensing mechanism.
Referring to Figure 1, the sensing device comprises a flexible housing, in this case a sphere [1], containing a sensing mechanism. The sensing device can communicate wirelessly using a radio or magnetic link [4] to a computing device [2] in order to transfer information about the actions its senses. The computing device [2] may be, for example but not limited to, a smartphone, computer tablet or personal computer, with a wireless connection means. Optionally, the sensing device may also have a mounting mechanism [3] to store the device when not in use. This mounting mechanism may also serve to recharge the battery in the sensing device.
Figure 2 shows how the sensing mechanism may be embedded within the flexible housing sphere. The sphere can be constructed using a mouldable thermoplastic flexible foam. Within the sphere an appropriate pocket [7] is formed to enable the sensing mechanism [5] to be fitted and secured. Those skilled in the art will be aware that it is also possible to mould the sensing mechanism directly into the sphere on a permanent basis. The housing format may easily be changed to other shapes such as cubes or oblongs.
Figure 3 shows a block diagram of the sensing mechanism. The mechanism contains a microprocessor [11] and wireless transceiver [12]. Those skilled in the art will be aware that these functions may be achieved using a single electronic component such as a wireless system on chip (eg: CC2540 Texas Instruments, USA). The device measures acceleration forces using an accelerometer [9] as well as other environmental parameters such as temperature [15], The unit may be powered by a battery [14] such as a generic CR2032 coin cell (Duracell Inc, USA) or by a rechargeable cell. For the latter a rechargeable mechanism may be incorporated to allow wired or wireless charging for the cell.
The accelerometer [9] provides measures of acceleration in 3 or more axes. Optionally the accelerometer [9] may also contain a gyroscope to enable angular rotation to be measured.
The sensor may determine a gesture, such as shaking, throwing or catching, by monitoring the accelerative change of the sensor using the microprocessor [11] and determining if a threshold has been exceeded. The sensor may discriminate different gestures by using the orientation of the sensor and the speed or direction of rotation.
Furthermore, the sensor may determine patterns of gestures such as repetitive shaking and use this to provide additional information about the periodicity of the gestures.
The sensor may detect squeezing gestures. A variety of mechanisms exist to do this for example by the use of a strain gauge contained in the mechanism housing. However, the design advantageously provides an option to sense the movement of air within the mechanism storage cavity caused by the squeezing action by the use of a electret condenser typically found in microphone inserts [16] (ie: ABM-704-RC, ABM Ltd, UK). The insert [16] will detect the change in air pressure on its element and generate a change in its output which may be used after signal conditioning to trigger an indication of the event to the microprocessor [11],
The device may provide haptic feedback using a vibrator [10] to a user in order to provide indication of events to the user, or to confirm detection of gestures.
A light indicator [8] using microminiature LEDs may also be used in the case of housing devices which are translucent.
Power may be conserved when the unit is not in use by using the accelerometer to detect an absence of activity below a threshold and enabling the microprocessor [11] to place the unit into a power saving mode. The device may use the accelerometer to wake from power down mode by detecting for example the acceleration forces occurring when the device is picked up or shaken.
The reliability of the sensed gesture may be improved by combining a starting orientation followed by an acceleration change in an axis to define a specific gesture.
The microprocessor [11] on detection of gestures may communicate these via messages via wireless transceiver [12], for example using the Bluetooth™ Low Energy protocol, to a remote device (see Figure 1 [2]).
The remote device may interpret these gestures in a number of ways, for example but not limited to, triggering musical sounds, interacting with games, controlling aspects of the remote device operation. In addition, the remote device may analyse aspects of the gestures or events sent and make appropriate responses back to sensing device to trigger the device to provide user feedback.
