CROSS-REFERENCE TO RELATED APPLICATIONS 
     This Application is a continuation-in-part of U.S. application Ser. No. 12/388,764 now issued U.S. Pat. No. 8,479,961 titled “Device Holder of a Transport Apparatus”, which is incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     The present general inventive concept generally relates to a touch device holder, and more particularly, to a touch device holder capable of being attached to a transport apparatus, such as a stroller. 
     Various features have been developed in order to enhance a comfort level of a user of a transport apparatus, such as a stroller. However, these features are often limited to enhancing a comfort level of the user who moves and navigates the stroller (hereinafter “user”), rather than a user, such as a child, being transported by the stroller (hereinafter “rider”). 
     For example, a conventional beverage holder has been previously developed which includes a beverage containing receptacle and a clip which affixes to a handle bar from which the user moves and navigates the transport apparatus. However, the conventional beverage holder does not directly enhance a comfort level of the rider, since the beverage holder is disposed at some distance away from the rider. Accordingly, it is very difficult for the rider to access or use the conventional beverage holder. 
     Furthermore, conventional armbands have also been developed which are used to carry small portable media devices. However, these conventional armbands are not capable of being affixed to the transport apparatus in such a manner as to provide access to the media device stored therein to the rider. 
     Accordingly, a device holder capable of being affixed to a transport apparatus, such as a rearward facing stroller, which provides a user being transported direct access to the device stored therein is desired.

     Referring to the drawings,  FIGS. 1 through 4  illustrate an exemplary embodiment of a device holder  100  according to the embodiments of the disclosure. The device holder  100  includes a main body  110  and a device storage compartment  120 . As illustrated in  FIG. 1 , the device holder  100  may be detachably coupled to handle bars  20  of a user transport apparatus  10 , such as a stroller, so that a device  30  stored within the device storage compartment  120  may be visible from a child compartment  40  of the stroller  10 . In one embodiment, the device holder  100  may be integrated into the stroller  10  in an embedded, semi-embedded, or substantially non-detachable matter. For example, in one embodiment attachment/detachment of the device holder  100  may require use of tools, such as a screwdriver, racket, Allen wrench, and the like. The device holder  100  may be made of a rigid plastic or other solid and approximately inflexible material designed for the specific circumference of the handle bars  20  and length between bars  20  of the stroller  10 . In another embodiment, the device holder  110  can be formed from a fabric, which is able to be affixed (e.g., Velcro, adjustable straps, etc.) about the handlebars  20  of the stroller  10  in a secure fashion. A hybrid collection of different materials for the device holder  100  are contemplated for embodiments of the disclosure. 
     In some embodiments, the device holder  100  may be detachably coupled to various other portions of the stroller  10  so that a child placed within a user storage compartment  40  may have a clear line of sight to a device  30  stored within the device storage compartment  120 . A line of sight refers to an angle for viewing a screen  30  of the device. A ninety degree angle (approximately orthogonal to the plane of the screen) and is a “baseline” for a line of sight, where a range of plus/minus thirty five degrees may be within viewing parameters of the device  30 . Different screens for device  30  can have known optimized viewing angles, which may be dependent on lighting conditions, and these device  30  specific angles are relevant for determining a line of sight proper for a device holder  100  in a given usage situation. 
     Compartment  40  is a volumetric space in which a child resides. This space can be a reclining one, as shown in  FIG. 1  and  FIG. 16 , can be designed for a child sitting upright (as shown by  FIGS. 12 and 15 ), or can be a largely unrestrained volume (such as a volumetric area for passengers of a Wagon). 
       FIG. 12  and  FIG. 15  both show the device holder  100  positioned for a child sitting in a rear-facing stroller. The device holder  100  is positioned between the handlebars  20  of the stroller  10 . The touch-screen device  30  may be within touch range of the child, as shown in  FIG. 12 , or may be slightly outside the touch range in absence of the child sitting fully upright, as shown by  FIG. 15 . 
     The device holder  100  may be able to be tilted for a “more optimal” viewing angle. Using  FIG. 1  as a reference, the device  30  may be connected to the device holder  100  around a pivot point  35 . The pivot point  35  can permit a screen of a device  30  to be adjusted for different angles  25 . In one embodiment, angles  25  (e.g.,  FIG. 16 ) between zero and three-hundred and sixty degrees are possible. When at a zero angle  25  in  FIG. 1 , a child in the carrier  40  may see a backside (opposite of a screen) of the device  30 . When at a 130 degree angle  25 , a child in the carrier  40  may have an optimal or at least a reasonable viewing of a screen. When at a two hundred and seventy degree angle  25 , a parent pushing the stroller may be able to easily see playback on a screen of the device  30 . Mechanisms are contemplated to lock the screen able to pivot along a pivot point  35  at any of a variety of angles of use. 
     Turning to  FIG. 12 , a pivot point  35  is formed toward a bottom of the device holder  100 . A predefined distance of a top mounted plane  36  results in an angle adjustment so that a child sitting in the carrier  40  is able to have an improved angle. FIG.  15  also shows an adjustment in a viewing angle caused by a top positioned extender  37 . The pivot point  35  in  FIG. 15  is also bottom mounted.  FIG. 16  shows how the angle adjustment available via the device holder  100  permits a person pushing the handles  20  to view the surface of the device  30 . 
     Referring now to  FIGS. 2 and 3 , in embodiments, the main body  110  of the device holder  100  includes front and back sides  111  and  112  and top and bottom ends  113  and  114 . The main body  110  may have a predetermined height  116  which may correspond to a desired dimension of a device  30  to be stored thereby and a predetermined width  117  which may correspond to a desired dimension of the stroller  10 . Specifically, the width  117  can correspond to a width between handlebars  20  of the stroller  10 , as the device holder  100  can be designed to position the screen of the device  30  between the handlebars  20 . In one embodiment, the device  30  can occupy a volumetric void between the handlebars. For example, the overall depth of the device holder  100  when positioned can be approximately equal to a radius of the handlebars  20  times two. This arrangement permits the device holder  100  to form a plane approximately equivalent to that of the handlebars  20 , which can be highly beneficial for folding many strollers, which an excessive depth would otherwise prevent folding, or would require the removal of the device holder  100  from between the handlebars  20  during a stroller-folding process. 
     The depth need not be perfectly matching the radius of the handlebars  20  times two, as any depth, which permits the stroller  10  to fold in its typical fashion, which may be a variation of the radius time two, which is dependent on stroller design), is functionally beneficial (enables folding without removing the device holder  100 ). For example,  FIG. 13  shows the device holder  100  with a depth slightly greater than two times the radius of the handlebars  20 . The addition permits the device holder  100  to fit around the handlebars  20 , and form a substantially planar surface for holding the device  30  and other items. As shown in  FIG. 13 , additional pockets  41 ,  42  for a mobile phone and a bottle exist. Others are contemplated. Different form factors for touch devices (7 inch, 10 inch, and the like) determine the amount of area (of a child facing plane) consumed by the device  30 . The remaining space can be utilized for additional storage and/or for peripherals related to the device  30  (e.g., an additional battery for extended use, a set of speakers, etc.). The width between handlebars  20  can vary between different stroller designs. Further, some stroller handlebars are designed to fold-into each other, in which case the device holder  100  may also automatically fold/reposition the device  30 , so as to permit quick stroller compaction/expansion (for taking in/out of a trunk, for example) without removing the device holder.  FIG. 14  shows an embodiment of a backside of the device holder  100 , which includes an additional storage pocket  43 , and a device angle adjuster  50 . 
     In some embodiments, the width  115  of the main body  110  may correspond to a distance between two handle bars  20  (possibly adjusted to be slightly greater to surround the perimeter of the outer surface of the handle bars  20 , or slightly less to entirely fit inside the inner surface of the handlebars  20 ) of the stroller  10 , and the height  116  of the main body  110  may correspond with a desired portion of the handle bars  20 . Frictive surfaces (e.g., rubber is a good frictive surface functioning against plastic/meta of a handlebar  20  surface) can be added in some embodiments, to establish a high co-efficient of friction between the device holder  110  surface  60  (e.g.,  FIG. 4 ) and a surface portion of the stroller (e.g., handlebar  20  surface) to prevent unintentional sliding of the device holder after it is positioned in a desired location relative to the handle-bars. In one embodiment, the positioning of the device holder  110  is such that telescoping functions of the stroller  10  are not impeded (for adjusting the handlebar height). In other embodiments, clamps, pins, top and/or bottom position holders (fixed about the circumference of each handlebar) and other mechanisms are able to be utilized to secure a relative position of the device holder  100  to the stroller  20 . 
     In an exemplary embodiment, the front side  111  and the back side  112  of the main body  110  may be integrally formed from a single sheet of material into various shapes, such as a cylindrical shape (see  FIGS. 2 through 4 ). This sheet of material may be flexible, such as made of fabric and/or may be rigid, such as made of a rigid plastic. When a fabric outer surface is utilized (as shown in  FIGS. 14 and 15 , for example) a rigid interior material, such as a metal, wood, plastic, and the like, can be utilized for stability and to add extra rigidity to the plane formed by the device holder  100  in contemplated embodiments. 
     In some embodiments, the main body  110  may include various elastic materials which allow the main body  110  to be easily installed onto and/or over the handle bars  20  of the stroller  10 . However, the present general inventive concept is not limited thereto. That is, in alternative exemplary embodiments, the main body  110  may be formed of multiple sheets of other materials, such as thermoplastics, which may be detachably coupled to the handle bars  20  of the stroller  10 . Combinations of different materials and elements can also be utilized. These combinations can enable desired properties (such as an ability to fold the stroller without removing the device holder  110 ), while still achieving a level of support for the device  30  and other storage compartments, when in use. 
     Referring to  FIGS. 2 and 4 , the device holder  100  includes the device storage compartment  120  coupled to a surface  118  of the main body  110 . The device storage compartment  120  may include a front wall  121 , first and second sidewalls  122  and  123 , and a bottom wall  124 . In addition, the device storage compartment  120  has a top end  125  and a bottom end  126  which respectively correspond with the top and bottom ends  113  and  114  of the main body  110 . As evident from  FIGS. 13 and 15 , the front wall  121  can be a substantially planar surface. It may extend significantly beyond a plane formed from the handle bar  20  in one embodiment (as shown it extends beyond the handlebar plane at a distance corresponding to the length of the first and second sidewalls  122  and  123 . In another embodiment, a concavity cavity can form between the handle bars  20 , within which the device  30  is able to be positioned, to minimize its extension beyond a plane formed from the handle bars. As shown by  FIG. 13 , multiple different compartments  41 ,  42  (with different sidewalls) are contemplated in one embodiment. 
     In further exemplary embodiments, the front wall  121 , the first and second sidewalls  122  and  123 , and the bottom wall  124  may define a cavity  127 , wherein a device  30  (see  FIG. 5 ), such as a DVD player, may be stored. As noted, this cavity  127  may at least be contained partially within the space between the handlebars  20 . In addition, the device storage compartment  120  includes an opening  128  disposed at the top end  125  of the device storage compartment  120  to provide access to the cavity  127 . The device  30  may be stored within the cavity  127  of the device storage compartment  120 . 
     In one embodiment, instead of a cavity  127 , the device can include a holder (which grips the sides of the device  30 ), or can include a hook-and-loop fastener mechanism for attaching/detaching the device (See embodiments shown in  FIG. 13 , for example). 
     In some embodiments, the device storage compartment  120  may further include a cover (not illustrated) disposed at the top end  125  of the device storage compartment  120  which may be used to close the cavity  127  from an external environment. That is, the cover may be used to completely isolate the cavity  127  from the external environment. 
     In further exemplary embodiments, the main body  110 , the device storage compartment  120 , and/or the cover may be formed of a material which protects the device  30  from the external environment. For example, in an exemplary embodiment, the main body  110  may be formed of material which is waterproof or water resistant in order to protect the device  30 , which may be stored within the device storage compartment  120 , from moisture. However, the inventive concept is not limited thereto. That is, in contemplated embodiments, the main body  110  may formed of a material which may protect the device  30  from electrostatic discharge (ESD). In addition, in alternative exemplary embodiments, the main body  110  and the device storage compartment  120  may be formed of various other materials, shapes, and sizes, as desired. 
     In some embodiments, the device storage compartment  120  may be formed of a similar or substantially similar material as that of the main body  110 . However, the inventive concept is not limited thereto. However, the present general inventive concept is not limited thereto. That is, in some embodiments, the device storage compartment  120  may include a plastic or metal portion in order to provide structural support from the storage compartment  120  and also to protect the device  30  stored therein from external forces. 
     In alternative exemplary embodiments, the cavity  127  which is defined by the device storage compartment  120  may also provide storage for the device  30  while the device  20  is not in use. For example, as illustrated in  FIG. 1 , the device storage compartment  120  provides storage for the device  30  while the device  30  is being used. However, although not illustrated, the device storage compartment  120  may also provide storage for the device  30 , when the device  30  is not being used. 
     In an alternative exemplary embodiment, referring now to  FIG. 2 , the main body  110  may further include a fixing member  130  which has a freely disposed first end  131  and a second end  132  which is coupled to the surface  118  of the main body  110 . In exemplary embodiments, the fixing member  130  may be disposed between the top end  113  of the main body  110  and the top end  125  of the device storage compartment  120 . In one embodiment, the device storage compartment  120  may be removable, to minimize bulk when the stroller is folded, permitting folding without removing the device holder  110  (which still requires removal of the device  30  and storage compartment  120 , which otherwise would inhibit proper folding of the stroller. 
     In further exemplary embodiments, the fixing member  130  may be formed in various shapes, such as rectangular or cylindrical shape. The fixing member  130  may be made from an elastic or non-elastic type material. However, the present general inventive concept is not limited thereto. That is, the fixing member  130  may be formed in various other shapes and/or materials, as desired. The fixing member  130  may in some embodiments assist in folding or guiding a fold of the device holder  100  for easy storage when a stroller is compacted (folded). 
     In exemplary embodiments, the first end  131  of the fixing member  130  may be attached to the surface  118  of the main body surface, and the second end  132  may be detachably coupled to the main body surface  118 . In the current exemplary embodiment, the first end  131  of the fixing member  130  may be attached to an area of the surface  118  of the main body  110  disposed between a first side  135  of the main body  110  and the first sidewall  122  of the device storage compartment  120 . 
     The second end  132  of the fixing member  130  may include a first securing portion  133 , such as a portion of Velcro™, a hook, a button, a snap, or other coupling device, attached thereto in order to be detachably coupled to a second securing portion  134 , such as a portion of Velcro™, a hook, a button, a snap, or other coupling device, which is coupled to the surface  118  of the main body  110 . 
     In the one embodiment, the second securing portion  134  may be coupled to an area of the surface  118  of the main body  110  disposed between a second side  136  of the main body  110  and the second sidewall  123  of the device storage compartment  120 . 
     Embodiments, where the storage device  100  is made of fabric, the fixing member may include straps, which make the surface of the device holder  110  taught relative to the handle bars  20 , where friction is utilized to retain the position thereafter. In other embodiments, snap fasteners (in an interior of the fabric, so that once positioned about the handlebars, the device holder fits “snuggly”, lacing holes (for lacing a ribbon, rope, or other material about the handlebars (e.g., like eye-holes in shoes for attaching strings) may be used to secure the device holder  100  to the handlebars  20 . A form and nature of the fixing member  130  is not to be limited, so long as the fixing member permits the device holder  110  to be affixed to the handlebars  20  in a relative stable position, in a manner enabling the device holder to support the included device  30 . 
     In exemplary embodiments, as illustrated in  FIGS. 1 through 4 , the device holder  100  may be installed over the handle bar  20  portion of a stroller  10 . The device storage compartment  120  may then be positioned such that a child disposed within the user storage compartment  40  may have a clear line of sight to a device  30  which may be held by the device holder  100 .
