The present invention makes improvements existing indicator device with the unique combination and various newly the having a shave of each feature, improves the comfort of indicator device.For this reason, the invention provides a kind of indicator device, this indicator device prevents that when supporting user's hand the wrist of hand and finger and joint are in extreme posture position, for example wrist stretches, under the palm omnidirectional of hand, the interior receipts or the abduction of thumb.The shape of this device also makes the canalis carpi pressure reduce, reduces contact pressure on the wrist sensitizing range by wrist being lifted to workplace top.Therefore, this indicator device in use makes the attitude of going smoothly with wrist more loosen, reduce the static load of muscle and alleviate tensity.
According to one aspect of the present invention, one uses at the indicator device on the workplace and comprises that one can place the bottom surface on this workplace and the sensing parts of at least one finger control.In one embodiment, this indicator device is a computer tracking ball device.
This device comprises a upper surface, and metacarpal bone-phalanges (MP) joint and the Guan Ding of at least a portion in the MP joint of the 3rd finger preferably of second finger in the palm district of a contact user palm arranged on this upper surface.The remainder height of the aspect ratio upper surface of this relative bottom surface of Guan Ding.Because one of multinomial repetitive operation needs to use the second and/or the 3rd finger to press the button when using this device, and this relates to main MP joint motions around these fingers, so this Guan Ding advantageously provides from these MP joints to the main support of wrist.
This upper surface stretches and forms a proparea, stretches and form a back zone and stretch and form an outskirt to the MP joint of export-oriented the 4th and the 5th finger downwards to user's wrist backward downwards to the finger tip of forward direction second and the 3rd finger downwards from Guan Ding.One transverse uplift outwards stretches from Guan Ding, the MP joint of the 4th and the 5th finger in contact palm district (part that may also have the 3rd finger MP joint).This transverse uplift is downward-sloping from the hat top, makes hand away from direction under the palm omnidirectional.The hypothenar region of hand is supported in this back zone.
Guan Ding is preferably relative with the back zone, and the bottom surface is enough high, and wrist is remained on workplace top, makes wrist be positioned at nearly neutral position and seldom stretches or do not stretch, and reduces by the contact pressure on the wrist sensitizing range of causing with the workplace Long contact time.
The back zone recedes downwards with enough big curvature, avoiding contacting the canalis carpi district of palm, thereby reduces the pressure on the canalis carpi.For example the general structure in back zone makes middle part and the close end at least of avoiding contacting canalis carpi, but can contact the distal portion of canalis carpi.In one embodiment, the curvature that forwards makes progress greater than the proparea of the curvature on the backward directions of back zone.
The back zone comprises one " Yuji point (thenar void) ", avoiding supporting thenar region, and the relative point device free movement thereby thumb can be suspended in down on the thumb neutral position.This has eliminated pressure and load on the thenar region that is caused by the thenar support in the existing mouse apparatus.
This housing comprises that a medial surface and its part expose this medial surface with the tracking ball in the face of thumb.This medial surface is desirably generally recessed with the zone of tracking ball adjacency.This medial surface have in the tracking ball lower left one inwardly the flange of configuration be used for the distal phalanx of thumb support.
Guan Ding and back zone are preferably enough high, so that the distal phalanx of thumb is resisted against on this flange or the workplace, on the rest position between interior receipts and the abduction extreme position.In one embodiment, the about halfway of thumb between interior receipts and abduction.
The proparea can comprise the button of placing the second and the 3rd finger thereon.Button preferably aligns with the phalanges of the second and the 3rd finger respectively, and like this, each finger can be pushed downwards and action button and move not stiff or nervous (receipts or abduction promptly) effectively at neutral position basically.

Fig. 8 illustrates the palm and the synoptic diagram of proficiency in each district on every side.
Fig. 1-7 illustrates a housing of Trackball device 10 with sensing parts of at least one finger control.This device 10 comprises an asymmetric upper surface 12 and a normally flat bottom surface 14 of operating on a smooth workplace.The one preferably circular hat top 16 that is used for contacting the palm district of user's palm is arranged on the upper surface 12.The remainder height of the aspect ratio upper surface 12 of 16 relative bottom surfaces 14, hat top.Trackball device 10 structures of Fig. 1-7 make and are suitable for making right-handed user to use, but should point out, the also available principle of the invention can be used to structure and make to be suitable for the Trackball device (for example mirror image of this embodiment) that sinistral user uses.
Fig. 8 illustrates a right hand 20, comprises first finger or thumb 21, second finger 22, the 3rd finger the 23, the 4th finger the 24 and the 5th finger 25.Each finger in second to the 5th finger has three phalanges, i.e. distal phalanx 26, middle part phalanges 27 and proximal phalanx 28.Thumb 21 comprises a distal phalanx 26 and a proximal phalanx 28.Metacarpal bone and carpal bone extend between five finger 21-25 and the wrist 30.The MP joint of finger 21-25 is between proximal phalanx 26 and the corresponding metacarpal bone of finger 21-25.Fig. 8 illustrates a contact region 32 of the tight below, MP joint that generally is positioned at the second and the 3rd finger 22,23.Preferably, contact region 32 is positioned at the tight below of the part in the MP joint of second finger 22 and the 3rd finger 23 MP joint.The hat of Trackball device 10 top 16 is used for contacting and support the contact region 32 of user's hand 20 among Fig. 1-7.Therefore, hat top 16 asymmetricly inwardly is positioned at device 10 upper surfaces 12 left sides.
As shown in Figure 8, thumb 21 bottoms are thenar region 34, and the another side of palm is a hypothenar region 35.Canalis carpi 36 is between thenar region 34 and hypothenar region 35.
Shown in Fig. 1-7, upper surface 12 tilts to a proparea 40 downwards forward from being preced with top 16, and this proparea is used for supporting the second and the 3rd finger 22,23 and preferably also has the 4th to point 24 distal portion.Upper surface 12 tilts towards the back zone 42 of wrist 30 to one downwards backward from hat top 16.Upper surface 12 16 outwards tilts to the outskirt 46 in MP joint of the 4th and the 5th finger 24,25 on hand 20 the right downwards from hat top.Because circular crown top 16 tilts to bottom surface 14 downwards on all directions of afore mentioned rules, so hand 20 can more pivot and deflection on the neutral position, and away from extreme posture position, the static load on hand 20 each joint reduces as a result.The superficial makings that prevents that hand from sliding can be arranged on the upper surface 12.
Shown in Fig. 1,2 and 4, the transverse uplift 47 of outskirt 46 is outwards stretched in the profile formation one between proparea 40 and the back zone 42 from hat top 16.From Fig. 4, can see the most clearly, a succession of arch 49 expressions between profile available apparatus 10 front portions of outskirt 46 and the rear portion on this direction.Transverse uplift 47 regions cover the summit of each arch 49.
Because one of a plurality of common repetitive operation relate to second and/the three finger, 22,23 buttons of firmly for example pressing in the proparea 40 during operative installations 10, therefore contact region 32 is supported on and is preced with that to push up on 16 be favourable at least a portion place in the MP joint of the MP joint of second finger 22 and the 3rd finger 23.The great majority action of these fingers 22,23 is carried out around the MP joint.Hat top 16 provides from these MP joints to the main support of wrist 30.The shape on hat top 16 preferably can support more roomy contact region 32 shown in Figure 8, to obtain support and load distribution uniformly.Hat top 16 is the relatively flat district of upper surface 12, can be by defining from the angle of the relative bottom surface of AP, summit.For example, as shown in Figure 3, hat top 16 can be one around summit AP, the angle φ of bottom surface 14 is less than about 10-25 ° zone relatively.Width W generally is about the 1.25-2 inch.
In addition, transverse uplift 47 is used for supporting the MP joint (part that may also have the MP joint of the 3rd finger 23) of the 4th and the 5th finger 24,25.Device 10 is firmly caught in the MP joint of the available the 4th and the 5th finger 24,25.Support hand 20 by the MP joint at finger 22-25, hat top 16 and protuberance 47 static loads that reduce on hand 20 each joint are worked finger 22-25 more neutrally.
As shown in Figure 5,16 preferably relative bottom surfaces 14 with back zone 42, the hat of upper surface 12 top are enough high, user's wrist 30 is remained on the workplace top at 14 places, bottom surface.For example, the maximum height on hat top 16 is at least about 1.25 inches, is preferably about 1.5-2.25 inch.Support the 16 downward slopes from the hat top of second to the 5th finger 22-25 in proparea 40 and outskirt 46, the raising of wrist 30 makes wrist be positioned on the nearly neutral position and seldom or do not have wrist to stretch, thereby the static load at wrist 30 places reduces.Wrist 30 is lifted to can prevent wrist 30 on the workplace the sensitizing range because of being under pressure and load with the workplace Long contact time.It also can limit wrist 30 about action, use better that forearm muscle is held, operating control 10.This also can reduce the tensity of wrist 30.In a preferred embodiment, when hand 20 usefulness contact regions 32 were resisted against on the hat top 16, no matter what angle forearm becomes with workplace, wrist 30 was lifted to the workplace top.
Shown in Figure 4 and 5, upper surface 12 stretches to proparea 40 downwards with easy grade gentle slope from hat top 16, ends at the leading edge 48 on 14 sides, bottom surface.Because the gradient in the proparea 40 of upper surface 12 is mild and wrist 30 is raised by hat top 16 and back zone 42, therefore at least the second and the 3rd finger 22,23 and preferably also have the MP joint of the 4th and the 5th finger 24,25 to support hand 20 with relative smaller angle.For example, as shown in Figure 5, the angle θ of MP joint is approximate identical between the second and the 3rd finger 22,23 metacarpal bone and proximal phalanx, and the MP bending generally is about 10-50 °.In certain embodiments, angle θ is about 20-40 °.In the embodiment shown in fig. 5, Trackball device 10 handles support to for example metacarpal bone and bottom surface 14 almost parallels of the second and the 3rd finger 22,23, and angle θ is decided by zone and bottom surface 14 angulations of device 10 upper surfaces 12 in 16 the place aheads, hat top.
Because the angle of MP joint of finger 22-25 is mild, therefore point the full stretching, extension (being straight position) that 22-25 avoids the MP joint or the extreme position of extreme crooked (the fist position of promptly holding with a firm grip), thereby hand 20 loosens in the attitude of MP joint.This is desired and since with the second and/or the 3rd finger 22,23 around the MP joint control button and point 22-25 with some or all and hold Trackball device 10 repeatedly.
Proparea 40 make the second and the 3rd finger 22,23 sagging rather than be suspended in aerial to descending slope with attitude more neutral and that loosen.This attitude can reduce the tensity of muscle.
In the embodiment shown, the ratio of curvature proparea 40 of back zone 42 backward directions forwards to curvature big, therefore shown in outline line among Fig. 5 45, upper surface 12 to descending slope in back zone 42 than in proparea 40 suddenly.Back zone 42 is preferably in the curvature enough big (promptly enough steep to descending slope) on the backward directions, to avoid contacting user's canalis carpi 36.This is avoided canalis carpi 36 pressure boosts, thereby reduces the pressure on the canalis carpi.Be noted that avoiding contacting canalis carpi 36 required curvature is decided by distance between the size of hand 20, particularly contact region 32 and the canalis carpi 36.The hand certain for size or magnitude range is certain, back zone 42 structures make has enough curvature, to avoid contacting canalis carpi 36.
The hat top 16 of upper surface 12 preferably is supported on relative bottom surface 14, the MP joint of second finger 22 than on the high slightly height in the MP joint of the 3rd finger 23.In an alternative embodiment, also can be on sustained height the MP joint support of the second and the 3rd finger 22,23.Because the transverse uplift 47 in the MP joint of upper surface 12 outskirts, 46 upper supports the 4th and the 5th finger 24,25 (part that may also have the MP joint of the 3rd finger 23) is downward-sloping, so the MP joint of the aspect ratio second finger 22 in these MP joints is low.Owing to successively decrease along transverse uplift 47 from the height in three-Di, five MP joints, the 2nd MP joint to the, therefore hand 20 outwards turns right, make hand to neutral position ground more away from palm omnidirectional under (being that palmar aspect is to the below) position, palm slightly inwardly is tilted to the left, and reduces static load.As shown in Figure 3, hat top 16 enough wide (for example width W is at least about the 1-1.5 inch), the gradient on outskirt 46 outward directions is enough mild, makes hand 20 be unlikely to outwards to slide to the right.In one embodiment, the curvature of back zone 42 on backward directions of the ratio of curvature upper surface 12 on outskirt 46 outward directions is little.
Shown in Fig. 1-7, Trackball device 10 comprises that one is positioned in the face of the medial surface 50 on thumb 21 one side.This medial surface 50 intersects along convex ridge 51 in one and upper surface 12, is formed between convex ridge 51 and the bottom surface 14.Can see the most clearly from Fig. 5, convex ridge 51 14 stretches upwards hat top 16 at device 10 leading edge 48 places from the bottom surface, is stretched over the trailing edge of bottom surface 14 at device 10 then downwards.Interior convex ridge 51 constitute upper surfaces 12 to inner boundary and medial surface 50 to the coboundary.The rear portion at 42 places, upper surface 12 back zones of Trackball device 10 is stretched at the rear portion 52 of medial surface 50 backward.
Can see the most clearly from Fig. 1 and 2, the rear portion of device 10 is distortion to the right outwards.The rear portion 52 of medial surface 50 and the back zone 42 of upper surface 12 are formed the right of the thenar region 34 that outwards is positioned at hand 20, thereby avoid supporting thenar region 34.Therefore, device 10 shape forms one " Yuji point ", and thumb is suspended on the thumb neutral position for 21 times, thus pining down of not being subjected to that thenar supports in the existing Trackball device and can install 10 free movements relatively.Different when supporting thenar region 34 with thenar, thenar region 34 is not stressed or load.Therefore, back zone 42 contacts, supports the hypothenar region 35 of hand 20 as the hypothenar region supporting surface but do not contact, supports thenar region 34 or canalis carpi 36, except with thenar region 34 side contacts taking place sometimes.
Can see the most clearly from Fig. 5, Trackball device 10 comprises its a part of exposing inside thereof face 50, faces a ball 58 of thumb 21.The position of ball 58 and size cosily are placed on it for the distal phalanx 26 of thumb 21, make thumb 21 roating sphere 58 in different directions easily.
Shown in Fig. 1,3,5 and 6, medial surface 50 is preferably recessed with the zone of ball 58 adjacency.There is a flange 53 medial surface 50 inboard below ball 58, in the upper outer of ball 58 leading edge 54 is arranged.Flange 53 is used for the distal phalanx 26 of stationary support thumb 21, although thumb 21 also can be supported on the workplace.Flange 52 can tilt as shown in the figure, but also substantial horizontal.Recessed medial surface 50 helps generating an open space around ball 58, but make thumb 21 not be subjected to the pining down of housing of device 10 and free movement to handle ball 58.Like this, but user's handle 20 is handled ball 58 when remaining on the upper surface 12 of device 10, around housing during with thumb 21 manipulation balls 58 hand 20 need not to lift or be in any stiff or nervous position.
In another embodiment, thumb 21 along its phalanges 26,28 directions move and during roating sphere 58 ball 58 move up and down cursor.Thumb 21 makes the cursor move left and right around the rotation in its MP joint.This layout reduces the stiff action of thumb 21 when normally handling ball 58, thereby reduces user's stressed and load on hand.
As shown in Figure 5, upper surface 12, particularly on hat top 16 and in back zone 42, enough high with respect to the bottom surface, in when needing the distal phalanx 26 of thumb 21 being placed on flange 53 or workplace between receipts and the abduction on the resting guard.For example, the maximum height on hat top 16 is at least about 1.25 inches, preferably is about the 1.5-2.25 inch.Abduction is meant that thumb 21 moves apart the palm of hand 20.The palm abduction is meant that thumb 21 and palm plane vertically move apart palm, and radially abduction moves apart palm with being meant thumb 21 and palm plane parallel.The interior receipts is meant that thumb 21 also stretches to the front portion of hand forward on the palm plane.Arrow 55 expression thumbs 21 outside exhibition positions are put mobile, and arrow 56 expression thumbs 21 are inwardly received the position and moved.Thumb 21 abductions take place when too far away from hat top 16 when upper surface 12 makes thenar region 34 be positioned at the too high and/or ball 58 in workplace top.When making thenar region 34, when workplace is too near, receives in the generation upper surface 12.Abduction and interior receipts are on the extreme position attitude of thumb 21, and static load is very big as a result, therefore will add and avoid.Thumb 21 is used for holding Trackball device 10 and handles tracking ball.Thumb 21 is remained on the neutral position, is favourable with the static muscle load that reduces on the thumb 21.In one embodiment, device 10 is supported on thumb 21 on the flange 53 on the resting guard of about halfway between (also can on the workplace) abduction and the interior receipts.
In addition, when thumb 21 reached the extreme higher position in roating sphere 58 processes, it highly preferably was not higher than the height of second finger 22.Therefore thumb 21 keeps not abduction when roating sphere 58, to reduce tensity.In addition, anxiety is caused to guarantee thumb 21 too not deflect into the abduction position left when the roating sphere 58 in the position close enough of ball 58 hat top 16.For avoiding the extreme position of abduction and interior receipts, the angle between the metacarpal bone of thumb 21 and second finger 22 is preferably in about 20-60 ° the scope.
Shown in Fig. 2-4 and 6, the simultaneously lateral surface 60 of the distal phalanx 26 of adversary 20 the 5th finger 25 is arranged on the right of device 10.Lateral surface 60 extends between the outskirt 46 and bottom surface 14 of upper surface 12.Lateral surface 60 is used for contacting the 5th finger 25, is generally its distal phalanx 26, also can randomly comprise its middle part phalanges 27.Shown in Fig. 2,4 and 6, the outskirt 46 of upper surface 12 is at the lateral surface 60 other lower concave parts 64 that a support the 4th finger 24 is arranged.One outer convex ridge 65 is arranged between lower concave part 64 and the lateral surface 60.In this embodiment, 60 contacts of lateral surface the 5th finger 25.Lower concave part 64 is used for stable support the 4th finger 24, prevents that its from outwards sliding to the right.In another embodiment, lateral surface 60 also can be used to support the 4th finger 24.
Shown in Fig. 1,2 and 6, device 10 includes the second finger button 72 of placing second finger 22 thereon and places the 3rd finger button 73 of the 3rd finger 23 thereon in the proparea 40 of upper surface 12.Second finger button 72 aligns with each phalanges of second finger 22, and these phalanges align with the bending axis in the MP joint of second finger 22.The 3rd finger button 73 aligns with each phalanges of the 3rd finger 23, and these phalanges align with the bending axis in the MP joint of the 3rd finger 23.Because the second and the 3rd finger 22,23 is main around its MP joint motions, so this alignment makes the second and the 3rd finger 22,23 touch the button 72,73 down effectively at neutral position, carries out along the bending axis in its MP joint thereby point 22,23 motion.This is avoided pointing 22,23 and carries out causing the distortion of obvious fatigue or laterally move (being abduction or interior receipts) and so on stiff or tonic action.Button 72,73 best long enoughs make the hand and the finger that vary in size all can handle Trackball device 10 and button 72,73 at least a portion in the MP joint of the MP joint of second finger 22 and the 3rd finger 23 when placing the hat of upper surface 12 to push up on 16.In addition, the size of ball 58 is suitable for different big or small hands with the position, when hand is supported on the hat top 16 thumb is worked more like a cork.
The second and the 3rd finger button 72,73 has front 74,75 on device 10 leading edges 48 sides.Front 74,75 preferably exceeds above the leading edge 48 of device 10.Even thereby the second and the 3rd finger 22,23 fronts 74,75 that extend through button 72,73 also are convenient to press the button 72,73.From Fig. 4 and Fig. 6, can see the most clearly among this embodiment, front 74,75 is suspended at leading edge 48 tops of device 10.
The height of the second and the 3rd finger button 72,73 is all low than hat top 16.On the button 72,73 indentation 72A, 73A are arranged preferably,, prevent outwards the slip away upper surface 12 of devices 10 of hand 20 to the right with the finger of stable support more 22,23.
Shown in Fig. 1,2,4 and 6, between the second and the 3rd finger button 72,73 roller 84 is arranged.Roller 84 for example becomes can rotate relative to the housing that installs 10 in device 10 inner upper supports.Roller 84 is generally handled by second finger 22, and preferably each phalanges along second finger 22 rotates.Each phalanges of second finger 22 generally aligns with the bending axis in the MP joint of second finger 22.Rotate around its MP joints because second finger 22 is main, so this alignment makes second finger 22 effectively handle roller 84 with neutral position, thereby the rotation of second finger 22 is carried out along the bending axis in its MP joint.This is avoided causing the stiff or tonic action of obvious fatigue.
