+    * @brief Detects contiguous regions (blobs) of `1`s in a 1D binary array and computes their movement.

+    * This function identifies blobs in the input binary array `touchArray`, calculates their start 
+    * positions, sizes, and centers, and returns the movement of the blobs compared to their positions 
+    * from the previous function call.
+    * 
+    * @param touchArray Pointer to the 1D binary array representing touch data. Each element is expected to be 0 or 1.
+    * @param size The size of the `touchArray`.
+    * @return A vector of integers representing the movement of each blob's start position since the 
+    *         last invocation of `detect1D`. The size of the returned vector is `maxNumBlobs`.
+    * 
+    * @note
+    * - The function updates the global variables `blobStartPos`, `blobSize`, `blobCenter`, 
+    *   and `lastState_blobPos`.
+    * - The number of blobs detected is limited by `maxNumBlobs`.
+    * - If the number of blobs exceeds `maxNumBlobs`, additional blobs are ignored.
+    * 
+    * @warning
+    * - Ensure that `touchArray` has at least `size` elements to avoid out-of-bounds access.
+    * - The function relies on external global variables (`blobStartPos`, `blobSize`, `blobCenter`, 
+    *   `lastState_blobPos`, `maxNumBlobs`, `blobAmount`). Ensure they are initialized appropriately 
+    *   before calling the function.
